Abstract:
Because the action of the swelling pressure, the settlements caused by the transmitted load from the structure on expansive soils, and the settlements calculated by classic theories of soils mechanics are different. This swelling pressure acts in opposite direction to the weight of the building. In this paper, the authors propose the use of a volumetric strain coefficient by settlements exp, in a soil-structure interaction algorithm taking into account the expansive soil behavior in the reduction of the settlement magnitude when a building is placed above soil. It’s necessary to know the initial properties of the expansive unsaturated soil and the load building conditions. A laboratory process is described for determining the aexpcoefficient.

Full text
Abstract:
The moisture characteristic of a swelling soil is the result of complex interaction between the soil water potential and imposed mechanical stresses. This can give rise to soil water profiles which cannot be interpreted by soil water theories for non-swelling soils. Agricultural soil physics has been concerned primarily with highly structured surface soils, and has developed simple theories for the effects of stress on soil water relations in swelling soils. These simple theories ignore the effect of lateral stress in the soil. Civil engineers, on the other hand, dealing mainly with less complex soils at depth, have developed more complex theories for the effect of three-dimensional stress states on soil water relations. This paper shows how the effect of three-dimensional stress can and should be included in soil water studies of swelling soils, and gives examples to demonstrate the possible magnitude of such effects.

Abstract:
Chicken feathers are composed mainly of avian keratin, a fibrillar protein with a complex structure, and important properties such as durability, hydrophobicity, being chemically unreactive, and depending on the specific function can change its morphological and inner structure. This study takes advantage of these features and for the first time the use of keratin from chicken feathers to modify characteristics on expansive soils is reported. Swelling characteristics of remolded expansive soil specimens were studied through varying the percentage of keratin fiber content using 0.25, 0.50, 1.00 and 3.00 wt%. One-dimensional swell-consolidation tests were conducted on oedometric specimens, specific surface area was determined using methylene blue, and degree of saturation was also analyzed. Finally random distribution and interaction between keratin structures and soil were studied by scanning electron microscopy. The results show that randomly distributed fibers are useful in restraining the swelling tendency of expansive soils. The maximum reduction of pressure (43.99%) due to swelling is achieved by reducing the void ratio, which can be reached with the addition of chicken feather keratin structures to the expansive soil. Finally, the mechanism by which discrete and randomly distributed fibers reduce swelling pressure of expansive soil is explained.

Abstract:
The swelling behavior of clay minerals is widely known for its importance in soil and environmental sciences and its detrimental effects in engineering fields. Although more than 70 percent of all clays are of mixed-layer types, the vast majority of the previous experiments and simulations are focused on pure clays, which cause the swelling mechanism of the widespread mixed-layer clay (MLC) and its role in soils are little understood, especially the most common illite-montmorillonite (I-M) mixed-layer clay (MLC). This paper reports on a molecular dynamics (MD) study of the differences in swelling behavior between I-M MLCs containing K+ and Na+ and Na-montmorillonite (MMT). It captures the evolution of quantitative properties such as basal spacing d, interaction energy, and many hydrogen bonds in the clay interlayer, increasing hydration for the first time through the scripts. It is found that MLCs have smaller swellings than Na-MMT due to the asymmetric interlayer charges and mixed counterions in the I-M interlayer. However, in terms of the interaction energy for the in-depth reason of swelling, it is found that the clay-clay interaction energy and the clay-ion interaction energy drop, while the clay-water interaction energy increases with increasing hydration. In addition, the attractive interaction of clay-bound water seriously promotes swelling, and it is mainly composed of Coulomb interaction and Van der Waals interaction. The higher the K+ concentration, the more noticeable these phenomena are. Besides, it is also reported that the number and distribution mechanism of hydrogen bonds in MLCs are very different from that of pure clay. This work provides insight into the molecular mechanism for initial swelling and clay-bound water interaction in widespread MLCs. This will help to decipher its specific role in soils and minimize clay swelling.

Full text
Abstract:
An attempt has been made to study the effect of zeolite formation on the volume-change behaviour of kaolinitic soil. This is studied in terms of two criteria, namely concentration and period of interaction. Conventional consolidation tests have been carried out to determine the extent of change in swell and compressibility of kaolinitic soils remoulded with water and inundated with an alkali solution. It was observed that abnormal swell occurs during unloading when specimens were inundated with a 4N alkali solution. While allowing a longer interaction period at 6.25 kPa, it was found that swelling in kaolinitic soils is induced after time lags of 30 and 15 days on inundation with 1N and 4N alkali solutions, respectively. Equilibrium is reached after 50–70 days in kaolinitic soils, however, and loading was undertaken later. A 16% swelling was observed in kaolinitic soils when inundated with a 4N alkali solution, indicating that zeolitization of kaolinite results in swelling at the seating load provided the period of interaction is sufficient. X-ray diffraction studies confirm the formation of zeolite.Key words: alkali, consolidation, kaolinite, swelling, X-ray diffraction, zeolite.

Abstract:
The results of infiltration (wetting) experiments conducted on expansive soils demonstrate several requirements and constraints to the techniques used for the study of wetting performance of such soils. In part, these constraints are a necessary outcome of limitations imposed by the difficulties (impossibility?) of measurement of swelling pressure at the wetting front. To provide a better insight into the development of swelling and reaction pressure in the soil during the wetting process, the energies of interaction between particles and water are examined, especially in regard to those forces developed in the Stern layer. The Grahame modification of the Stern layer has been used in this study to provide the basis for calculations of interaction energies in the inner and outer Helmholtz planes. Comparison with high-pressure consolidation of a sodium montmorillonite at very close particle separation distances suggests that the addition of the energies of interaction developed in the Stern layer to the Gouy–Chapman model would permit the double-layer model to be extended to close particle spacings. Whether this is sufficient to account for the stage I wetting process is a question that remains to be further studied. For the present, the test results suggest that the expression for the total soil–water potential ψ should account for those forces of interaction, thereby providing a better account of the physical processes involved in wetting of the expansive clay and a more realistic diffusion coefficient for the total wetting process. Key words : soil-water potential, osmotic potential, swelling pressure, volume change, wetting front, Stern layer, inner Helmholtz plane, outer Helmholtz plane, Coulombic forces, dipole–dipole interaction, ion–dipole interaction.

Full text
Abstract:
Hydraulic conductivity of soil is strongly dependent on soil structure, which can be degraded during wetting and leaching. It was hypothesised that this structural degradation is dependent on initial aggregate size distribution and soil texture. The general aim of this study was to investigate the effects of aggregate sizes and soil textures, and their interactions, on the structural degradation and saturated hydraulic conductivity (Ks) of smectitic soils under different saline and sodic conditions. The studied soils were clay and loamy sand soils with low (~4.5) or high (~10) exchangeable sodium percentages (ESP), and with aggregate sizes in the ranges: (i) <1 mm (small aggregates); or (ii) 2–4 mm (large aggregates). The Ks values of the samples in a column after slow or fast pre-wetting were determined by means of a constant head device. Different wetting rates and leaching under various saline and sodic conditions had no effect on the Ks of the loamy sand; however, the Ks values of this soil with large aggregates were an order of magnitude greater than those of the soil with small aggregates. In contrast, in the clay soil with large aggregates, the Ks values after fast pre-wetting were significantly smaller than those after slow pre-wetting, probably because of aggregate slaking. No significant effects of the wetting rates on Ks were found in clay soil with small aggregates. An increase in the ESP in the clay soil decreased the Ks by a factor of 1.5 for the large aggregates and by an order of magnitude for the small aggregates, mainly as a result of increased clay swelling. Leaching the clay soil with deionised water significantly decreased the Ks values, partly because of clay dispersion. Although significant structural degradation of the clay soil occurred during leaching, the Ks values were smaller in the soils with small aggregates than in those with large aggregates, indicating the importance of the initial aggregate size on Ks even in soils that are prone to structural damage.

Abstract:
Water main pipes buried in expansive soils are often subjected to severe distress subsequent to installation. Excessive stresses may be induced due to either differential movement of the soils or swelling pressures from the soils along the pipes, impairing their performance or even breaking them. Field monitoring is an important means for understanding soil behaviour and its interaction with water mains. For this purpose, field instrumentation was successfully installed to monitor the performance of a section of water main placed in a well-developed area of a city neighbourhood where more frequent pipe breakage had occurred in recent years. The instrumentation included sensors to measure pipe wall strains, pipe displacement, in situ soil water content, soil pressure, and temperature. The instruments were installed in both the soil backfill and native soil around the backfill. This paper presents the analyses of monitoring data collected during the first 3 years after instrument installation. It was observed that the soil and pipe behaviour was affected significantly by soil properties and seasonal changes and correlated closely with the change pattern of the local meteorological conditions.

Abstract:
The shrinkage and swelling of clayey soils is a natural hazard, which may significantly affect buildings. Foundation settlement caused by this geohazard for buildings constructed on expansive soils undergoing a drought period was studied. A soil–structure interaction model is proposed. The hydromechanical coupling is taken into account by using the state surface approach. Settlement is evaluated according to building stiffness, ground hydromechanical properties, surface suction variation, suction profile, and foundation depth. The uncertainties are considered by using the Monte Carlo approach, and an application has been performed for the average settlement assessment of a group of buildings. This paper outlines the significant dependency of the final settlement on the building stiffness. It highlights the benefits of rigid buildings and deeper foundations to reduce vulnerability to this geohazard.

Abstract:
Dans ce travail, les risques naturels considérés concernent des mouvements de terrains qui résultent de deux phénomènes principaux : retrait et gonflement des sols argileux et l'affaissement à grand rayon lié à la présence des cavités souterraines. Ceux-ci provoquent des tassements différentiels du sol qui génèrent des désordres sur les constructions environnantes : dégâts et fissuration des murs porteurs en maçonnerie, particulièrement aux angles du bâti. Ces dégradations structurales induisent des conséquences économiques importantes dans le cas des maisons individuelles ; elles résultent d'un manque de résistance des maçonneries, du peu de raideur de leur système de fondation et du peu d'efficacité de leur système de contreventement. Cette recherche a pour objectif d'analyser la vulnérabilité du bâti et de proposer des méthodes de renforcement pour les constructions existantes ainsi que des recommandations de dimensionnement pour les constructions. Ces questions nécessitent une connaissance approfondie du phénomène des mouvements des terrains et des modalités de transfert de ces actions à une structure. Pour y répondre, quatre étapes principales ont été effectuées : une étude bibliographique, une analyse de l'interaction sol-structure, un développement d'une justification d'endommagement et d'une méthode de renforcement ou de dimensionnement ainsi qu'une analyse probabiliste des risques. L'étude bibliographique avec des analyses fonctionnelles et statistiques, d'abord, propose un profil de la maison sensible à l'aléa naturel et des cas typiques des désordres sur la construction. Le développement des modélisations par éléments finis ensuite permet d'étudier les phénomènes d'interaction sol-structure. L'analyse de l'interaction sol - structure, au moyen de modélisations par éléments finis, permet d'obtenir des sollicitations dans la maçonnerie. D'abord, des modèles analytique et numérique simplifiés ont été développés pour modéliser des structures simples telles une semelle filante, un système de semelles d'une fondation filante ou un mur en maçonnerie sur un sol élastique de type Winkler ou Boussinesq. Ensuite, des modélisations de structures plus complexes avec tous les éléments du bâti ont été effectuées en développant un code aux éléments finis particulier qui a permis de calculer des bâtiments en maçonnerie sur un sol de type Pasternak. En vue de développer une justification d'endommagement ainsi qu'une méthode de renforcement et de dimensionnement adaptée pour risque «mouvement de terrains », les travaux de recherche focalisent sur la distribution des sollicitations obtenues par des modélisations et analysent les domaines de validité de la démarche proposée par les Eurocodes EC6 et EC8 pour les murs de contreventement en maçonnerie confinée (chainée) ou armée. L'analyse probabiliste des risques, couplant les modèles aux éléments finis développés avec la méthode des simulations de Monte-Carlo, a permis d'étudier la vulnérabilité des maisons individuelles selon les caractéristiques structurales représentatives du bâti existant, dans les régions les plus touchées par les mouvements de terrains. Les résultats de cette analyse ont été unifiés, au sein d'une méthodologie globale de l'évaluation de la vulnérabilité de structures, à l'usage, d'une part, des pouvoirs publics dans l'établissement de cartographies SIG des risques, et d'autre part de la capacité des procédés de renforcement à l'usage des industries
In the present work, the considered natural hazards concern to ground movements resulting from two main phenomena : shrinkage and swelling of clay soils and ground subsidence due to the presence of underground cavities. These phenomena cause differential ground settlements which generate disorders on the structures erected in their neighborhood : damage and cracking of masonry load-bearing walls, especially at the building corners. These structural degradations cause important economic consequences and losses in the case of dwelling houses. These damages result from a lack of masonry resistance or a small stiffness of the foundation system as well as a limited effectiveness of bracing system.This research aims to analyze the vulnerability of buildings and to propose a reinforcement method for the existing constructions as well as design recommendations for structures. These topics require a thorough understanding of the ground movements phenomenon and their transfer as actions on a structure. For this purpose, four main steps were performed : a literature review, an analysis of soil-structure interaction, a development of a damage justification and a method for reinforcement or design, as well as a probabilistic analysis of risk.The literature review with functional and statistical analysis, as a first step, provides a profile of the house susceptible to natural hazard effects and typical cases of building disturbances. The development of finite element method is therefore considered in order to study soil-structure interaction.The analysis of the soil-structure interaction using finite element modeling provides stresses in the masonry. First, simplified analytical and numerical models have been developed for simple structures such as a strip footing, a system of strips foundation or a masonry wall lying on elastic soil (Winkler or Boussinesq). Afterwards, modeling of more complex structures with the whole building elements was made by developing a particular finite element code that allowed the calculation of masonry buildings on a Pasternak soil. To develop a damage justification as well as the reinforcement and design building methods suitable for risk of “ground movements”, this work focuses on the stresses distribution obtained by numerical models and analyzes the validity domain of the approach proposed by Eurocodes EC6 and EC8 for confined masonry or reinforced masonry. By coupling the developed finite element models with the Monte-Carlo method, the probabilistic analysis of risk allows to study the vulnerability of dwelling houses having representative structural characteristics of existing buildings, erected in areas that are the most affected by ground movements. The results of this analysis have been unified into a global methodology for assessing the vulnerability of structures. This methodology is used, in one hand, for the development of GIS mapping of risks and, in other hand, for the reinforcement processes

Abstract:
Le changement climatique et les événements climatiques sévères tels que les périodes de sécheresse/humidification prolongées sont à l'origine du phénomène de retrait-gonflement dans les sols argileux. Ce phénomène est affecté par les interactions sol-végétation-atmosphère (SVA) et peut causer d’importants dommages structurels aux constructions légères telles que les bâtiments résidentiels. L’objectif de ce travail de recherche est de modéliser le comportement in situ du retrait-gonflement des sols gonflants dans un contexte SVA en se basent sur des outils numériques. Une méthode d'interaction sol-atmosphère est initialement présentée accompagnée d’un modèle couplé hydro-thermique du sol. Cette approche a été principalement mise en place afin de déterminer les conditions aux limites temporelles à la surface du sol en se basent sur la notion du bilan de masse et d'énergie pour déterminer a posteriori, les modifications spatio-temporelles de la succion du sol, de la teneur en eau et de la température. Cette approche a été validée à l'aide des observations in situ des sites instrumentés. Par la suite, l’influence de l’absorption d’eau par les végétations a été intégrée dans le terme source de l’écoulement de l’eau dans un milieu non saturé, à l’aide d’un modèle d’absorption d’eau de racine existant.Les variations temporelles de succion ont été postérieurement reliées au comportement volumique du sol en appliquant une approche simple développée à partir des résultats expérimentaux des essais de séchage/humidification réalisés dans la littérature. Les indices associés dans le plan indice des vides-log succion, ainsi que les paramètres complémentaires du modèle linéaire ont été corrélés aux paramètres géotechniques de base. L'approche proposée a été ultérieurement validée avec des données in situ fournies par la surveillance d’un site expérimental. Le site expérimental de Roaillan a été instrumenté afin de surveiller les modifications physiques du sol ainsi que le comportement structurel du bâtiment. Les comparaisons entre les résultats de la modélisation et les observations in situ de la succion du sol, la teneur en eau, la température et les mouvements du sol dans le temps ont montré une performance acceptable du modèle. L’approche a ensuite été appliquée pour étudier l’influence des projections climatiques futures (2050) sur les variables physiques et les mouvements du sol sur ce site. Trois scénarios RCP relatifs aux changements climatiques ont été examinés dans cette étude, qui ont révélé des différents comportements possibles à court terme et à long terme. Finalement, l'approche développée a été appliquée au territoire français en le divisant en six régions climatiques. Différents paramètres de sol ont été attribués à chacune de ces régions climatiques afin de définir les conditions de référence. En conséquence, l’influence de différents facteurs externes sur les mouvements du sol a été analysée sur une période donnée. Enfin, l’étude suggère les mesures adéquates à prendre pour minimiser l’amplitude du phénomène de retrait et de gonflement dans un contexte SVA
Climate change and severe climatic events such as long drought/rehydration periods are at the origin of the shrinkage and swelling phenomenon in expansive soils. This phenomenon is affected by Soil-Vegetation-Atmosphere (SVA) interactions and can cause severe structural damage to lightly loaded constructions such as residential buildings. The objective of this re-search work is to simulate the in-situ behavior of the shrinkage-swelling in expansive soils in a SVA context using numerical tools. A soil-atmosphere interaction method is primarily presented along with a coupled hydro-thermal soil model. This approach was established in order to determine primarily, the natural time variable boundary conditions at the considered soil surface based on the mass and energy balance concept, and secondly to determine the spatial-temporal changes of the soil suction, water content and temperature. This approach was validated using in situ observations of monitored sites. Thereafter, the influence of the water uptake by vegetation was incorporated in the source term of the unsaturated water flow theory, using an existing root water uptake model. Subsequently, the temporal variations of the soil suction were related to the volume change behavior using a simple approach developed based on the experimental results of drying/wetting tests performed in the literature. The associated volumetric indices in the void ratio-log suction plan, along with the complementary parameters of the linear model were correlated with basic geotechnical parameters. The proposed approach was validated with in situ data provided from an experimental site. The Roaillan experimental site was instrumented in order to monitor the soil’s physical changes along with the structural behavior of the building. Comparisons between the simulated and observed soil suction, soil water content, temperature and soil movements in time and depth showed an acceptable performance of the predictions. The approach was then extended to study the influence of future climate projections (2050) on the soil’s physical variables and movements. Three RCP climate change scenarios were considered in this analysis which revealed different possible behavior in both short term and long term. Finally, the developed approach was applied to the French territory by dividing it to six different climatic regions. Different soil parameters were attributed to each of these climatic regions in order to set the reference condition. Thereafter, the influence of different external factors was analyzed on the soil movements over a chosen period. The study finally suggests the adequate actions to take for minimizing the amplitude of the shrinkage and swelling phenome-non in a SVA context

Abstract:
Swelling clays cause tremendous amounts of damage to infrastructure. For the effective prevention of detrimental effects of these clays, and to optimize the beneficial properties for industrial applications it is necessary to clearly understand the fundamental mechanisms of swelling of clays. In this study, we studied the effect of fluid polarity on swelling and flow properties of swelling clays using molecular modeling and experimental technique for bridging the molecular level phenomenon of these clays with microstructure change, particle breakdown and macro scale swelling and flow properties. A wide range of fluids (Dielectric Constant 110 to 2.4) were used, those are also commonly present in landfill leachates. We were able to tie the properties of swelling clays at different length scales. Then, we simulated the solvation of clay sheets, studied the effect of discrete charge distribution, contribution of edge charges on swelling clays and discussed some fundamental assumptions associated with double layer theories.

Full text
Abstract:
A constitutive model based on rate-independent elastoplasticity concepts is developed and used to simulate the behavior of geologic materials under arbitrary three-dimensional stress paths. The model accounts for various factors such as friction, stress path and stress history that influence the behavior of geologic materials. A hierarchical approach is adopted whereby models of progressively increasing sophistication are developed from a basic isotropic-hardening associative model. Nonassociativeness is introduced as correction or perturbation to the basic model. Deviation of normality of the plastic strain increments to the yield surface F is captured through nonassociativeness. The plastic potential Q is obtained by applying a correction to F. This simplified approach restricts the number of extra parameters required to define the plastic potential Q. The material constants associated with the model are identified, and they are evaluated for three different sands (Leighton Buzzard, Munich and McCormick Ranch). The model is then verified by comparing predictions with laboratory tests from which the constants were found, and typical tests not used for finding the constants. The effect of varying initial density of a material on the stress-strain and volumetric response is investigated. An empirical relation is proposed, whereby one parameter is modified based on the initial density, such that improved predictions can be obtained without increasing the total number of parameters. Implementation of the nonassociative model in a finite element program to solve boundary value problems leads to a nonsymmetric stiffness matrix. Besides, using a nonsymmetric solver, three numerical schemes are investigated. The idea of the schemes is to modify the stiffness matrix such that a symmetric equation solver can be used. Prediction of stress-strain, volumetric response and CPU time for different schemes are compared with the predictions obtained using the nonsymmetric solver. The nonsymmetric equation solver used less CPU time and the solutions were more accurate. Based on the above findings, a soil-footing system is analyzed using the finite element techniques. The associative and nonassociative models are used to predict the behavior. For the nonassociative model, solution is obtained by using a nonsymmetric solver. Results obtained from both models are compared with a model footing test performed in the laboratory.

Abstract:
In this thesis primarily structural induced liquefaction potential was aimed to be analyzed. Also the effect of base isolation systems both on structural performance and liquefaction potential was studied. FLAC software was chosen for the analyses so that structure and soil could be modeled together. By these means the soil structure interaction effects were also examined. Four different structures and three different sites were analyzed under two different input motions. All the structures were also analyzed as base isolated. It was mainly found that depending on the structural type and for a certain depth the liquefaction potential could be higher under the structure than the one in the free field. Also it was concluded that base isolation systems were very effective for decreasing the story drifts, shear forces in the structure and liquefaction potential in the soil. It was also found that the interaction took place between structure, soil and input motions.

Abstract:
A field test is developed to assess the collapse susceptibility of soils rapidly and inexpensively. The in situ collapse test device measures the vertical deformations which occur in soils when they are subjected to stress and given access to water while under continuous load. Principles of statistics were employed to show that laboratory testing of soil specimens overestimate the magnitude of collapse as measured in the field and that the magnitude of collapse is, in part, a function of the soil moisture content at the time of loading and at the time of collapse. Good correlation was found between the spatial variability of collapsible soils with the location of alluvium terrace deposits and structurally damaged buildings.

Abstract:
The soil-structure interaction (SSI) has a significant impact on nuclear power plant (NPP) structures, especially for massive and rigid structures founded on soils, such as containments. The U.S. Nuclear Regulatory Commission’s (NRC) Standard Review Plan (SRP) provides the requirement and acceptance criteria for incorporating the SSI effect in the seismic design and analyses of NPP structures. The NRC staff uses the SRP for safety review of license applications. Recent studies have indicated that ground motions in recorded real earthquake events have exhibited spatial incoherency in high-frequency contents. Several techniques have been developed to incorporate the incoherency effect in the seismic response analyses. Section 3.7.2 of Revision 3 of the SRP also provided guidance for use in the safety evaluation of seismic analyses considering ground motion spatial incoherency effect. This paper describes a case study of the SSI and incoherency effects on seismic response analyses of NPP structures. The study selected a typical containment structure. The SSI model is generated based on the typical industry practice for SSI computation of containment structures. Specifically, a commercial version of SASSI was used for the study, which considered a surface-founded structure. The SSI model includes the foundation, represented with brick elements, and the superstructure, represented using lumped mass and beams. The study considered various soil conditions and ground motion coherency functions to investigate the effect of the range of soil stiffness and the ground motion incoherency effect on SSI in determining the seismic response of the structures. This paper describes the SSI model development and presents the analysis results as well as insights into the manner in which the SSI and incoherency effects are related to different soil conditions.

Abstract:
The effect of pile-soil interaction on structural dynamics is investigated for a large offshore wind turbine in the hurricane-prone Western Gulf of Mexico (GOM) shallow water. The offshore wind turbine has a rotor with three 100-meter blades and a mono-tower structure. Loads on the turbine rotor and the support structure subject to a 100-year return hurricane are determined. Several types of soil are considered and modeled with a distributed spring system. The results reveal that pile-soil interaction affects dynamics of the turbine support structure significantly, but not the wind rotor dynamics. Designed with proper pile lengths, natural frequencies of the turbine structure in different soils stay outside dominant frequencies of wave energy spectra in both normal operating and hurricane sea states, but stay between blade passing frequency intervals. Hence potential resonance of the turbine support structure is not of concern. A comprehensive Campbell diagram is constructed for safe operation of the offshore turbine in different soils.

Abstract:
It has been well recognized the importance of dynamic soil-structure interaction for several structures founded on soft soils. In order to examine the effects of soil-structure interaction, the substructure method is applied to the dynamic response evaluations of offshore platform. Since the offshore platform is generally subjected to severe dynamic forces such as wave, current and seismic forces, it is very important to clarify the dynamic response characteristics for the reliable design of the platform. For the idealized three-dimensional offshore platform subjected to random waves and seismic forces with the pile-soil foundation system, the dynamic response evaluations were carried out through the modal analysis. On the other hand, the uncertainty effects of dynamic forces and structural properties play very important roles on the reliability evaluations of offshore platform. If the limit state function is given by the most critical situations of dynamic responses, the reliability evaluations of the platform can be effectively calculated by the reliability index with the results obtained from Monte Carlo Simulation (MCS) method. Since the uncertainty of the random wave and seismic forces is critical for dynamic response evaluations, it is necessary to clarify the effects of uncertainties for the reliable design of the offshore platform.

Abstract:
In the present study, the influence of various scenarios of supply ship collisions, namely, bow, stern and also broad-side impacts on a jacket-pile-soil system is investigated. In the previous study of ship impact on an 8-leg North-Sea Jacket Platform by Amdahl et al. [2] and also other authors, the effect of jacket-pile-soil interaction was not considered. The collision points on the jacket structure are also taken as joints and mid-span of leg, horizontal and vertical braces, namely, hard and soft impact points. The speed and the weight of the colliding vessel are also varied for typical supply vessels. Several supply ship collision analyses are carried out for bow, stern and broad-side impact scenarios on an 8-leg North-sea Jacket platform It is observed that by taking into account the jacket-pile-soil interaction effects, in particular in softer clay soils the amplitude of displacement response after supply ship impact at the deck level is increased due to yield in the upper soil layers. Contrary to this finding, less linear dynamic effects can be seen in the studied jacket-pile-soil system subjected to the supply ship impact. It can also be concluded that for soft impact scenario, the dynamic effects in the global response of the platform located in the mainly OC clayey soil may be much less than those for hard impact scenario on the same platform. For instance, for a brace impact at its mid-span, a less significant dynamic effect has been observed than for a leg impact. The duration of impact in such cases is shown to play an important role in determining the dynamic influence of the platform response. The relative energy absorption of the platform is shown to be more for broad-side loading. It is shown that the global response of the jacket platform during the collision with a supply vessel might depend largely on the scenario of the impact and to some extent on the pile-soil behavior. It is found that for the bow and stern impact scenarios, the energy contribution of the local member dent or buckling might be more significant than for the broad-side loading for which the global frame energy contribution and the overall inertia effect of the platform might be a dominant factor.

Abstract:
This paper presents a general axi-symmetrical solid element to be used mainly for the calculation of added masses of water surrounding members of offshore structures, and in general, for multi-purposes such as analyses of shells of revolution, circular beams and plates, axi-symmetrical structures and soils, plane stress/strain problems. Since one element type is used for modeling of different media such as structures, soil and water, the element is very suitable to solve interaction problems. The element is derived parametrically so that changing values of parameters can generate flexible geometrical shapes in exact forms. In the element formulation, a constant shear locking is used to solve bending problems of beam like structures. A similar fluid element is also formulated to analyze fluid-structure interactions and to determine added masses of co-vibrating water. The added mass is calculated from hydrodynamic pressures, which are produced by fluid-structure interactions. In the paper, a special solution algorithm is presented for the coupled eigenvalue problem of the interaction. An analytic calculation of the added mass is also presented for members along which a constant variation of hydrodynamic pressure occurs. A couple of examples are provided to demonstrate applications of the elements explained. Added mass coefficients of offshore structural members (tubular members) are investigated for practical uses.
