Resumen
Wind energy industry has been growing tremendously in recent years. Tubular steel towers are currently dominant supporting structures for wind turbines. With the increase of the converter capacity, there is a great demand for higher supporting towers. However, structural vibrations in extreme wind events tend to become a major concern during tower design. To study wind turbine tower dynamics, an existing tubular steel tower was tested. Vibrational frequencies and damping ratios were identified. To avoid unexpected dynamic problems, a space frame steel tower has been proposed for supporting larger wind turbines. It is a structural system that can be assembled on-site by using prefabricated beams, columns, and brace members. A typical space frame steel tower was designed in this paper. Static loading, modal and buckling analyses of the tower were presented. It is expected to introduce engineers and designers more options for wind turbine tower design.

Resumen
Purpose The purpose of this paper is to investigate the static and dynamic inelastic response of rigid and semi-rigid connections of steel structures with concrete-filled steel tube (CFST) columns built in high seismic areas, and to compare it with those with open section columns. Design/methodology/approach CFST columns are frequently used in moment resistant steel frames located in seismic areas due to their inherent advantages, including their ductility, energy absorption capacity as well as their high bearing capacity. The smart combination of steel and concrete makes it possible to benefit from the advantages of both components to the maximum. This research work presents the nonlinear dynamic response of moment resistant steel frames with CFST columns, with rigid or semi-rigid connections, built in high seismic areas, according to the Algerian seismic code RPA 99/2003, European EC8 and American FEMA 356 to show the nonlinear characteristics of this type of structures, and their advantages over steel frames with open section columns. Findings The paper presents the advantages of using CFST columns with rigid and semi-rigid connections on the seismic response of portal steel frames. A high performance level in terms of ductility, plastic hinges distribution and their order of appearance has been obtained. It also shows the low effect of seismic loading on the structural elements with CFST columns compared to structures with open section columns. Originality/value The investigation of the numerical results has shown the possibility of their use in the seismic areas for their adequate performance, and also with respect to the design limits specified in the seismic guidelines. In addition, this study represents a first step to develop seismic performance factors for steel structures with CFST columns in Algeria, where the Algerian code do not include a comprehensive specification for the composite steel structures.

Resumen
The influence of forming condition on crash performance of thin-walled structures is investigated, in which high strength low alloy steel HSLA340 and dual phase steel DP590 are considered. Stamping and knife-edge-bending process were carried out respectively to form hat channels, and then, impact tests were performed on the spot-welded top-hat sections subjected to quasi-static and dynamic axial loading conditions to identify the forming effect on the crashworthiness. Regular progressive buckling (quasi-inextensional mode) was observed for knife-edge-bent specimens, while the stamped specimens showed peculiar collapse mode, especially, global instability existed for all the specimens under dynamic impacting and their energy absorption capacity was significantly reduced. The result demonstrates that for accurate assessing the structural performance detailed stamping history of sheet metal components should be taken into consideration.

Resumen
This paper presents the results of dynamic responses and fire resistance of concrete-filled steel tubular (CFST) frame structures in fire conditions by using the nonlinear finite element method. Both strength and stability criteria are considered in the collapse analysis. The frame structures are constructed with circular CFST columns and steel beams of I-sections. In order to validate the finite element solutions, the numerical results are compared with those from a fire resistance test on CFST columns. The finite element model is then adopted to simulate the behavior of frame structures in fire. The structural responses of the frames, including the critical temperature and fire-resisting limit time, are obtained for the ISO-834 standard fire. Parametric studies are carried out to show their influence on the load capacity of the frame structures in fire. Suggestions and recommendations are presented for possible adoption in future construction and design of similar structures.

Resumen
A four-ocular vision system is proposed for the three-dimensional (3D) reconstruction of large-scale concrete-filled steel tube (CFST) under complex testing conditions. These measurements are vitally important for evaluating the seismic performance and 3D deformation of large-scale specimens. A four-ocular vision system is constructed to sample the large-scale CFST; then point cloud acquisition, point cloud filtering, and point cloud stitching algorithms are applied to obtain a 3D point cloud of the specimen surface. A point cloud correction algorithm based on geometric features and a deep learning algorithm are utilized, respectively, to correct the coordinates of the stitched point cloud. This enhances the vision measurement accuracy in complex environments and therefore yields a higher-accuracy 3D model for the purposes of real-time complex surface monitoring. The performance indicators of the two algorithms are evaluated on actual tasks. The cross-sectional diameters at specific heights in the reconstructed models are calculated and compared against laser rangefinder data to test the performance of the proposed algorithms. A visual tracking test on a CFST under cyclic loading shows that the reconstructed output well reflects the complex 3D surface after correction and meets the requirements for dynamic monitoring. The proposed methodology is applicable to complex environments featuring dynamic movement, mechanical vibration, and continuously changing features.

Resumen
Steel tubular structures are somewhat entrenched for the wind turbine towers. Recently, steel hybrid lattice/tubular towers are being investigated as a conceivable answer for taller onshore wind turbines for which convectional steel tubular towers are less competitive. Hybrid lattice/tubular towers require a transition piece which serves as a connection between lattice and tubular part. As the transition piece is supposed to transfer all the dynamic and self-weight loads to the lattice and foundation, these structural elements present unique features and are critical components to design and ought to resist strong cyclic bending moments, shear forces, and axial loads. Well-designed transition pieces with optimized ultimate state and fatigue capacities for manufacturing contribute to the structural soundness, reliability, and practicability of new onshore wind turbines hybrid towers. This research focuses on the investigation of the transition piece for an onshore wind turbine hybrid tower. The 5-MW reference wind turbine and a hybrid lattice/tubular tower were simulated in the servo-hydro aero-elastic analysis tool (by ASHES software) from which the loads and dynamic response of the supporting structure were obtained. Cross-sectional forces at the transition piece elevation were calculated and the connection with the lattice structure is designed. The transition piece was designed by finite element model considering ultimate limit load and fatigue load, using nonlinear analysis and multiaxial fatigue for life-time prediction, respectively. Multiaxial fatigue life was calculated based on Brown–Miller and Smith–Watson–Topper methods. In comparison, Smith–Watson–Topper method comes out to be more conservative. Potential of using high-strength steel S690 was investigated.

Resumen
This paper deals with the numerical impact analysis of tubular thin-walled steel-made elements with induced folding for energy dissipation application. The excellent deceleration of the impacting mass of axial collapsing structures favors their use in energy dissipation applications, such as impact resistance and rockfall protection. Dynamic Finite Element analyses have been carried out to evaluate the performance of vertical assemblies of cold-formed steel cell-shaped elements welded on each other to form collapsible tubular elements. In turn, these have been gathered in groups and restrained by galvanized steel wires to create modules. The axial collapse, which is the most effective energy absorption mechanism, has been triggered by shaping the elements' edge as serpentine. In the analysis, several assembly configurations have been subjected to a freefall rhombicuboctahedron-shaped rigid block impact; Falling height, impact angle, and block mass have been varied to investigate their effect on the performance. The numerical results show a good agreement when compared to those obtained through a real-scale experiment.

Resumen
Compared with the traditional reinforced concrete columns, the concrete-filled steel tubular columns with a better restraint effect of steel tube on core concrete showed higher bearing capacity and ductility under static loads. However, except static loads, concrete-filled steel tubular columns are commonly exposed to the extreme dynamic loads including earthquake, explosion, and impact. The study on dynamic behavior of concrete-filled steel tubular columns is extremely significant to ensure their safety against such dynamic loads. In this article, a polyvinylidene fluoride piezoelectric smart sensor was proposed to monitor the axial impact bearing capacity of specimen based on stress monitoring under impact loads. The concrete-filled steel tubular columns with smart sensor embedded were tested, which considered the effects of both hammer impact heights and steel tube thickness on the axial impact bearing capacity. The impact bearing capacity calculated based on the monitoring results of polyvinylidene fluoride sensor is in good agreement with the measured values, which verifies the feasibility of this method. Moreover, it is found that the failure mode of concrete-filled steel tubular short columns is the local tearing failure or local buckling. In addition, non-linear finite element models were also established to study the effect of different parameters on the axial bearing capacity. The simplified formula for calculating the axial impact bearing capacity of concrete-filled steel tubular short columns was proposed based on the large amount verified model. Through the comparison between the calculation value and the test value, the formula is found to well reflect the axial impact bearing capacity of concrete-filled steel tubular short columns, which provides a reference for similar research.

Resumen
Blast-resistant capacities of 4 large scale circular Reactive Powder Concrete Filled Steel Tubular (RPC-FST) columns after exposure to fire are experimentally examined. The overpressures of shock wave, the deflections and strains of RPC-FST column specimens are recorded by advanced gauges. The influences of fire durations and scaled standoff distances of explosive charge on the dynamic behaviors and failure modes are discussed. It is shown that the RPC-FST columns remain excellent blast-resistant capacities after exposure to fire. RPC core column can be effectively confined by steel tube, but the blast-resistant capacities of RPC-FST columns are decreased as explosive charge or fire duration increased. The failure modes are transited from bending types to bending-shear types as explosive charge increased, and an obvious plastic hinge at mid-span section can be observed in the RPC-FST column with fire duration of 105min. It is also indicated that the maximum displacements of RPC-FST columns are more sensitive to fire duration than to explosive charge weight.

Resumen
South Africa has recently experienced challenges regarding electricity consumption and availability. As part of the country's Integrated Resource Plan, these challenges are to be addressed. This involves a 20 year plan which aims to increase electricity supply capacity as well as reduce the reliance on coal power as part of the global trend to become more environmentally friendly. Wind power, specifically, is to account for a large portion of the renewable energy that is expected to become available by 2030. This results in the need for the understanding of wind turbine design by South African engineers. The dynamic analysis of wind turbine structures, is of particular interest to Civil Engineers. Wind turbine towers are recently of the monopole or tubular type tower, predominantly constructed of either concrete or steel or a combination of both. Steel tubular towers above a height of 80m are generally not recommended for wind turbines owing to cost concerns as well as difficulties in meeting dynamic behaviour requirements. Concrete towers and steel-concrete hybrid towers are recommended for this height regime. The aim of this study was to assess the prospective use of steel tubular towers of varying geometric shape for wind turbines with tower heights of 80m or greater. The study focussed on the analysis of natural frequency and assessing the applicability of steel tubular towers of geometric shapes that have not been previously explored or reported. The turbine of choice for this study was the Vestas V112 3MW type as this is one of the most commonly used and more efficient turbines for towers of this height regime. The results of this study showed that steel monopole towers of heights of 80m and more are still viable options for wind turbine towers. Various geometric tower cases of heights varying from 80m to 120m, produced acceptable fundamental natural frequencies within the allowable frequency range for a Vestas V112 3MW turbine.

Resumen
Concrete filled steel tubular (CFST) columns are widely used in building and infrastructure projects throughout the world.Compared with other form of construction CFST columns offer superior structural performance and speed and ease of construction.Design procedures and recommendations provided in most of the design codes are often tedious and complex. There have been attempts to simplify the design procedure by providing a simplified expression to predict the capacity of a CFST under a general loading condition.In this thesis a rigorous analysis procedure was presented for the analysis of CFST beam-columns under general loading conditions.All the analytical results were verified by comparisons with the available test results and current ACI, AISC AND Eurocode 4 design codes. The comparisons demonstrated that the proposed numerical equations are accurate, and slightly conservative. Based on the numerical analysis, a simple and easy to follow calculation procedure was proposed for design of CFST columns under either uniaxial or biaxial bending moment and axial load.

Resumo: Este trabalho tem como objetivo apresentar análises comparativas entre estruturas metálicas treliçadas tubulares planas considerando as vinculações entre as barras como rotuladas e estruturas metálicas treliçadas tubulares planas considerando as vinculações entre as barras como rígidas. A motivação deste estudo foi determinar qual a importância da rigidez das barras no dimensionamento das mesmas estruturas quando são consideradas diferentes vinculações entre as barras. Foram encontradas diferenças nos dimensionamentos quando as barras são ¿curtas¿ e conseqüentemente, bastante rígidas. Nestes casos, onde as barras são rígidas, a consideração de rótula leva a resultados que não condizem com o comportamento real da estrutura e, conseqüentemente, a um dimensionamento inadequado da estrutura tubular. Para agilizar as análises, foi desenvolvido um software que automatiza as etapas principais de um projeto de estruturas metálicas tubulares planas, com o objetivo de enquadrar tais análises em condições que respeitem os parâmetros normativos de ângulos entre barras, limites de esbeltez, entre outros. As etapas automatizadas foram: geração automática de determinadas geometrias, cálculo dos coeficientes de pressão e forma do vento e pressão dinâmica, carregamento automático da estrutura, cálculo estrutural e dimensionamento da estrutura. O programa possui uma interface amigável, integrada e ágil que permite aos projetistas de estruturas metálicas realizarem diversas análises possibilitando de forma rápida a escolha da solução mais adequada para a estrutura
Abstract: This research has the objective to present a comparative analysis between steel plane tubular trusses that consider the member¿s end connections as released and steel tubular plane trusses that consider the member¿s end connections as non-released (rigid). This study intends to measure the member¿s stiffness importance for the design of these members when them are considered released or not. It was found differences when the members were ¿short¿ and very rigid. In this cases, when the members were rigid, the released consideration takes to results that don¿t represent the real behavior of the structure and, consequently, to an inadequate design of the tubular structure. To make the analysis faster, it was developed a software that automate the major steps of a steel tubular structure design, with the objective to fit the analysis in the standard design recommendations, like angles between members, stiffness limits, and others. The automated steps were: automatic generation of geometries, automatic wind pressure calculation, automatic structure load insertion, structural analysis and steel structure design based on Brazilian codes. The software has a friendly interface, which allows engineers realize several analyses and, thus, choose the most adequate solution for the structure

Resumo: O desenvolvimento de sistemas de cobertura pré-fabricados para grandes vãos, que tenham como características menor tempo de projeto, fabricação e montagem, aliado ao custo competitivo e fator estético, é tema de constantes estudos. O objetivo deste trabalho é desenvolver um sistema de cobertura metálica padronizado e modular utilizando perfis tubulares laminados sem costura. Este sistema se destina principalmente para coberturas de supermercados, shoppings, centros de distribuição, grandes lojas e indústrias, que necessitam de grandes áreas livres. Foi feita, inicialmente neste trabalho, uma descrição de todas as etapas envolvidas em um projeto, destacando, em cada uma, as vantagens e desvantagens da aplicação do perfil tubular. Através de estudos sobre os diversos sistemas de cobertura existentes, tanto no Brasil como no exterior, foi desenvolvido um sistema padronizado de cobertura para atender grandes vãos com utilização de perfis tubulares de seção circular. Para se avaliar o comportamento estrutural deste sistema, foi construído, de maneira inédita no Brasil, um protótipo de 900 m², para testar o sistema construtivo idealizado e realizar ensaios com os carregamentos reais neste tipo de estrutura. Foram realizadas análises experimentais e numéricas, que permitiram comparar o modelo real com o modelo computacional. Através dos modelos numéricos gerados, levando em conta a rigidez das ligações, foi possível identificar qual modelo computacional mais se aproxima com o real. Avaliando-se então o comportamento global da estrutura, com base em todos os resultados numéricos e experimentais obtidos, confirmou-se o comportamento previsto no cálculo computacional com o protótipo ensaiado

Through the study of existing roof systems, a new system using tubular steel sections was developed. To evaluate the structural behavior of this system a 900m2 prototype was built, an unprecedented occurrence in Brazil, to accomplish experimental tests with usual loads on this kind of structure. Experimental and numerical analyses were done, that allowed to compare the prototype with the numerical results. Evaluating the behavior of the entire structure, with all the results obtained on experimental tests and numerical analysis, it was concluded that the prototype is in accordance with the model

Resumen
This thesis explores the creation and assessment of semi-active control algorithms for both squat shear buildings and tall flexible structures. If cost-effective, practicable, semi-active structural control systems can be developed, the potential reduction in loss of both property and lives due to seismic events is significant. Semi-active controllers offer many of the benefits of active systems, but have power requirements orders of magnitude smaller, and do not introduce energy to the structural system. Previous research into semi-active controllers has shown their potential in linear simulations with single earthquake excitations. The distinguishing feature of this investigation is the use of appropriate non-linear modelling techniques and realistic suites of seismic excitations in the statistical assessment of the semi-active control systems developed. Finite element time-history analysis techniques are used in the performance assessment of the control algorithms developed for three and nine story structural models. The models include non-linear effects due to structural plasticity, yielding, hysteretic behaviour, and P-delta effects. Realistic suites of earthquake records, representing seismic excitations with specific return period probability, are utilised, with lognormal statistical analysis used to represent the response distribution. In addition to displacement focused control laws, acceleration and jerk regulation control methods are developed, showing that potential damage reduction benefits can be obtained from these new control approaches. A statistical assessment of control architecture is developed and undertaken, examining the distribution of constant maximum actuator authority for both squat shear buildings, and tall slender structures, highlighting the need to consider non-linear structural response characteristics when implementing semi-active control systems. Finally, statistical analysis of all results and normalised values shows the efficacy of each control law and actuator type relative to different magnitude seismic events. As a result, this research clearly presents, for the first time, explicit tradeoffs between control law, architecture type, non-linear structural effects, and seismic input characteristics for the semi-active control of civil structures.

Resumo: Este trabalho tem como objetivo o desenvolvimento de códigos de computador que têm a finalidade de automatizar as etapas principais de um projeto de estruturas metálicas através das linguagens AutoLISP e Delphi5. Os projetos de estruturas metálicas em estudo são os de coberturas com treliças planas constituídas de barras com perfis tubulares laminados sem costuras e seus contraventamentos. Estes perfis tubulares, ainda pouco utilizados em estruturas planas no Brasil, vêm sendo disseminados através do uso de programas que ajudam os engenheiros a utilizá-los adequadamente em seus projetos tendo em vista que resultam em estruturas mais leves e de fácil fabricação. Desta forma, houve a necessidade de desenvolver um sistema CAD/CAE, para automatizar a geração das geometrias das estruturas planas, além das representações gráficas do sistema geral tridimensional de contraventamentos da estrutura - CAD; exportar os dados para um programa integrado que realiza um processo otimizado de toda a análise estrutural e dimensionamento - CAE e, finalmente, retornar os dados processados para o ambiente CAD, para realizar o detalhamento automático das ligações da estrutura treliçada analisada. Todos os procedimentos adotados para automação dos projetos seguem recomendações de normas técnicas brasileiras principalmente a NBR8800/1986
Abstract: This work has as objective to show a software that have the goal to automate the main stages of a steel structural design, using AutoLISP and Delphi5 languages. The steel structural designs in case are the roofs formed by plane trusses made by hollow sections frames. These hollow steel sections, which are not highly used in plane structures in Brazil, are being disseminated by the use of softwares that help civil engineers to use them correctly in their designs, in view of that they result in less weighted and easy manufactured structures. So, there is the necessity to develop a CAD/CAE system, that will automate the generation of the geometries from plane structures and the graphical designs from the three-dimentional general system - CAD; also, we have the necessity to export the data to an integrated computer program that executes an optimized process from the entire structural analysis and design - CAE; and, finaly, to return the proceeded data back to CAD environment, to draw the automatic details from the connections of the analyzed structure. All the procedures and methods used to automate the design follows the specifications of Brazilian Design Codes, mainly the NBR-8800/1986

Resumen
This thesis presents the details of a study regarding both the use of linear viscous fluid dampers in controlling the interstory drift in steel moment frames, and the use of incremental dynamic analysis as a method of visualizing the behavior of these moment frames when subjected to seismic load effects. Models of three story and nine story steel moment frames were designed to meet typical strength requirements for office buildings in Seattle, Washington. These models were intentionally designed to violate seismic interstory drift restrictions to test the ability of the linear viscous fluid dampers to reduce these drifts to the point of code compliance. Dampers were included in one bay of every story in each model. These devices were used to produce total structural damping ratios of 5%, 10%, 20%, and 30% of critical. Undamped, traditional stiffness controlled models of both three stories and nine stories were also created for comparison purposes. Incremental dynamic analysis was used to subject these models to ten ground motions, each scaled to twenty incremental levels. Two new computer applications were written to facilitate this process. The results of these analyses were studied to determine if the linear viscous fluid dampers were able to cause compliance with codified drift limits. Also, incremental dynamic analysis plots were created to examine the effects of the dampers on structural behavior as damping increased from inherent to 30% of critical. It was found that including linear viscous fluid dampers in steel moment frame design can satisfactorily control interstory drift, and incremental dynamic analysis is a beneficial tool in visualizing dynamic structural behavior.

Resumen
Fundação de Amparo à Pesquisa do Estado do Rio de Janeiro
Este trabalho de pesquisa objetiva o estudo do comportamento dinâmico de pisos mistos (aço-concreto), em edificações de andares múltiplos, sob o ponto de vista de conforto humano, quando essas estruturas encontram-se submetidas às atividades rítmicas provenientes dos seres humanos. A definição das ações dinâmicas atuantes sobre os modelos estruturais foi feita com base em resultados experimentais, com os indivíduos praticando atividades rítmicas e não rítmicas associadas à ginástica aeróbica e saltos à vontade. Os modelos estruturais investigados baseiam-se em edificações mistas de andares múltiplos. O sistema estrutural é do tipo misto (aço-concreto), composto por vigas de aço em seção do tipo I e laje de concreto armado. A análise fundamenta-se na modelagem computacional dos sistemas estruturais, através do Método dos Elementos Finitos (MEF). São empregadas técnicas usuais de discretização, por meio do emprego do programa ANSYS. Uma análise paramétrica foi desenvolvida sobre três modelos estruturais, com dois, três e quatro pavimentos. Os valores das acelerações máximas encontradas na análise são confrontados e comparados com os limites propostos por recomendações internacionais. Os resultados obtidos mostram que os limites recomendados em diversas normas de projeto foram ultrapassados. Esses resultados demonstram que atividades rítmicas oriundas dos seres humanos podem gerar acelerações de pico elevadas, violando critérios de projeto, no que concerne ao conforto humano. Foi observado também que estas ações dinâmicas podem comprometer o conforto humano em pisos adjacentes, próximos do local onde a carga dinâmica está sendo efetivamente aplicada.
The present dissertation investigates the dynamic behaviour of composite floors (steel-concrete) in multi-storey buildings when subjected to the human rhythmic activities, considering human comfort aspects. The dynamic loads were obtained through experimental tests with individuals carrying out rhythmic and non-rhythmic activities such as stimulated and non-stimulated jumping and aerobics. The investigated structural model was based on several building composite floors. The structural systems are composed of a composite (steel/concrete) solution made of an I steel profile and a reinforced concrete slab. The proposed analysis methodology adopted the usual mesh refinement techniques present in the finite element method simulations implemented in the ANSYS program. A parametric analysis was developed, using three different building composite floors with two, three and four storeys. The parametric study considered correlations between analytical and numerical results found in the technical literature. The results, in terms of maximum accelerations (peak accelerations) were compared with the limits proposed by design recommendations. The results indicated that the limits suggested by design recommendations are not satisfied. Such fact shows that these rhythmic activities may generate peak accelerations that violates design criteria when the human comfort is considered. It was verified that these dynamic loads generate considerable perturbations on adjacent areas. The influence caused by dynamic actions in adjacent floors near to the place where the load was applied also can compromise the human comfort.

Resumen
Steel tubes are widely encountered in industrial applications and in offshore structures. This is mostly because of their superior axial load carrying performance, low resistance against fluid loads and easy handling during construction and transportation. Cylindrical structural members, however, very often happen to become subject to accidental lateral damages which are detrimental to their load carrying performance. Collision between supply ships and legs and bracings of offshore oil platforms, impact from heavy dropped objects on these members or denting during installation of marine structures are examples of such accidents. Prior to an accident, cylindrical members are usually carrying their normal operational loads. It is very important to include the effects of this service load (pre-loading) in evaluation of the behaviour of impacted member. The pre-loading may change the dynamic characteristics of the member or degrade its load carrying capacity. While the performance of cylindrical members subjected to lateral impact has been extensively researched, few studies can be found on the impact behaviour of pre-loaded tubular members. This paper reports results from a numerical study on axial pre-loading effects on the dynamic and quasi-static behaviour of cylindrical shells subjected to transverse impact loads. Results obtained appear useful for a more realistic design of tubular members and in choosing feasible and reasonable post impact repairing and strengthening schemes.

Resumen
In published literature, Solid Expandable Tubular (SET) is defined as a down-hole cold work process to expand a tubular to attain desired inner diameter. Tubular expansion process is a complicated process and a number of challenges are associated with its usage. However, proper planning before execution may lead the operators for more options that can affect important parameters such as; tubular length after expansion, hole diameter, expansion force, tubular structural integrity, post expansion properties, suitable material for tubular, selection or design of associated tools for expansion, and optimal selection of system components based on formation type, to name a few. Further studies are needed to overcome the challenges of these problems. Most of the published materials in this area mainly present the experience of using the technology without pointing directly to the technical challenges and understanding the fundamentals behind it. The successful expansion process shall make sure of no fracture, burst, collapse or any damage in the tubular; constant tubular diameter along the tubular; and the structural integrity of tubular and tubular connections. In general, expansion process involves placing a cone inside tubular and through the application of force at one end of the cone tubular expands. The sudden release of energy, at the end of expansion process, acts as a dynamic excitation to the tubular-fluid-formation system, which may affect tubular material properties and geometry, and is termed as pop-out phenomenon. The dynamics of problem is solved by considering inner/outer fluids and tubular itself. The forward and backward movement of pressure waves in inner and outer fluid and the stress wave in tubular is solved analytically as a coupled problem. It is assumed that the three mediums are uniform in nature, formation is isotropic, damping is negligible, fluid velocity behind cone is low and wave lengths are large compared to borehole diameter. It was found that the fluctuating stress levels at the fixed end of the tubular causes permanent ripples, which will increase tubular diameter beyond allowable limit and/or will cause converging and diverging sections within the tubular resulting from constructive or destructive interference of stress wave originating after pop-out. In order to limit the number of runs for computer simulation, particular type of tubular and well are chosen, hence keeping the geometrical parameters constant for all simulation. Other parameters are changed and their effects on pop-out phenomenon are determined. The results show that changing the formations, inner and outer fluid densities have no effect on the inner fluid pressure and axial stress for specific tubular materials. However, significant variations occur in outer fluid pressure. Among all tubular materials high Mn steel alloy experiences lower stress values. The current study can be used to aid in selection of reliable materials for SET system to minimize the affect of pop-out phenomenon. Also, formations variation varies outer fluid pressure. In addition, all expansion ratios follow the same pattern in parameters variation.

Resumen
Marine structures can experience loads coming from steep, non-linear waves. A transient response of the structure can be amplified in some circumstances due to phenomenon known as “ringing”. Exact conditions of the ringing response excitation are not well known and various definitions of what constitutes a ringing event appear in bibliography. This article aims at identification of ringing events for a slender marine structure subjected to the second order nonlinear irregular waves. Loads on the structure are calculated from Morison equation with extensions known as Rainey’s slender body theory. Consistent second order formulation for the flow kinematics above mean water level is employed. The excitation load is non-linear due to wave non-linearity, Morison equation’s drag term and non-linear inertia terms which can be found in Rainey’s formulation. The structure’s dynamic response is obtained by Finite Element calculations in time domain. Overall randomly-excited vibrations are analysed by statistical and spectral methods, and application of Continuous Wavelet Transform (CWT) is presented. The simulations show a number of sudden, high amplitude resonant events which can be classified as ringing.
