Full textAbstract:
The commercial software platform SAP2000 has been used to design base isolated buildings supported by Triple PendulumTM isolators; however, limited full-scale test data are available to validate the use of the software for this application. Additionally, previous work has demonstrated that several pitfalls must be avoided when modeling these types of structures in SAP2000. The ability of SAP2000 to predict key engineering demand parameters used in the design of a base-isolated building is examined by using methods and assumptions employed in current design practice. The SAP2000 analysis results are compared to the data obtained from shake table tests of a full-scale base-isolated building and comparable predictions obtained from a more complex OpenSees analysis model of the same building. This study suggests that when methods and assumptions common to engineering practice are applied, SAP2000 can predict the responses with sufficient accuracy for design.

Full textAbstract:
Structure under long-term load, environmental erosion, material aging, especially under the seismic action can cause damage accumulation and bearing capacity decrease. In order to make sure its safety and reliable, avoid extreme cases of catastrophic accident, it is necessary to carry out the engineering structural health diagnosis. Using SAP2000 software, seismic response analysis for a two layer reinforced concrete frame structure is carried out. The laws of the acceleration response time history and spectrum under different seismic action were found out by discussing structure in no damage and different damages. The results showed that no matter where the damage located, the top node response increment is bigger than the middle node, the peak of acceleration response spectrum changes little with the beam damage degrees changing. Selecting the acceleration response peak of the top node as a structural damage index is feasible in the damage detection and identification of engineering structures, but analyzing the response spectrum for damage detection is unpractical.

Full textAbstract:
The Tubed Mega Frame (TMF) is a structural system for high-rise building developed by Tyréns AB. Compared to conventional structural systems, the TMF is a coreless system that transfers the loads through the perimeter of the building instead and in turn enables ability to support new architectural shapes and forms of buildings. This thesis covers an initial study of a high-rise building with an unconventional shape implementing the TMF system, the Cable-stayed Building, which consists of a slanted tower with a cable-supported cantilever. The study of the building was divided in to a geometrical study and a cable study. The geometrical study was carried out to gain an initial understanding of the global structural behavior by altering specific geometrical parameters. The cable efficiency in terms of total vertical forces was investigated in the cable study by comparing different cable arrangements, cable diameters and prestressing forces for a fixed global geometry. The studies were performed under linear and nonlinear static conditions using the finite element software SAP2000 and ETABS. The results from the geometrical study showed that the cable efficiency increases in terms of larger vertical cable forces with a less inclined building and longer cantilever length. In addition, the results showed significant effects of geometric nonlinearities considering P-delta for different geometric cases. Furthermore, a study of the axial forces in the mega columns indicated that the most inclined building in which no uplifting forces and barely any tension occur along the mega columns, is the 7° incline with cantilever length 73.4 m. As abovementioned, the efficiency of the cables was compared for different arrangements, cable diameter and prestressing forces. The results indicated that as the prestressing force increases, the efficiency of cables rises more for smaller cable diameter than for larger. Furthermore, the comparison of fan- and harp-shape cable arrangements showed that the latter, including three pairs of cables, gives the highest cable efficiency relative to the amount of steel required of the cantilever bracing system. Nevertheless, the study indicates that the cable forces are inherently dependent on many parameters, such as the sag effect considered in the modulus of elasticity and the stress inducing temperature, which in turn depends on cable diameter, prestressing force and cable arrangement. To conclude the study, a modal analysis showed that the Cable-stayed Building is classified as a stiff building according to the guidelines from Council on Tall Buildings and Urban Habitat. Further research on the structure could be carried out within different areas, as this thesis is only an initial study of the structure. For instance, material nonlinearities, dynamic responses of the building as well as soil structure interaction, should be investigated further.Tubed Mega Frame (TMF) är ett bärande system för höghus utvecklat av Tyréns AB. TMF är, till skillnad från nuvarande konstruktioner, ett system utan en bärande kärna som överför laster via byggnadens perimeter istället, vilket skapar nya förutsättningar gällande arkitektoniska former på höghus. I detta projektarbete genomförs en förstudie på en byggnad med en ovanlig design, Snedkabel Byggnaden, bestående av ett lutande torn och en konsol som bärs upp av kablar. Studien är uppdelad i en geometrisk analys och en kabel analys. Den geometriska studien syftar till att få en uppfattning om hur det globala bärande systemet beter sig genom att variera vissa geometriska parametrar. Syftet med kabel studiens är att undersöka kablarnas effektivitet genom att jämföra den totala vertikala kabelkraften med olika kabelsystem, kabeldiametrar och förspänningar för en fastställd geometri av byggnaden. Statiskt linjära och ickelinjära strukturanalyser genomfördes för båda studier i finita element programmen SAP2000 och ETABS. Resultaten från den geometriska studien visade att kabel effektiviteten ökar för en mindre lutad byggnad och en längre konsol, då kabelkrafterna ökar. Dessutom indikerar resultaten anmärkningsvärda effekter vid beaktandet av ickelinjäritet med P-delta för olika globala geometrier. En undersökning av axialkrafter i pelarna visar att den mest lutade byggnaden som inte ger upphov till upplyftande krafter och knappt några dragkrafter längs pelarna är byggnaden med 7° lutning och konsollängd på 73.4 m. Som tidigare nämnt undersöktes kablarna effektivitet genom att jämföra olika kabelsystem, kabeldiametrar och förspänningar. Resultaten påvisade att med högre förspänningar, desto mer ökar kabeleffektiviteten för mindre kabeldiameter än större. Dessutom visade jämförelsen mellan solfjäder- och harp-systemet att harp-systemet med tre kabelpar ger stört kabeleffektivitet i relation till stålmassan för stagningen i konsolen. Krafterna i kablarna beror i sig till stor del av exempelvis elasticitets modulen med hänsyn till kablarnas nedböjning och den spänningsinducerande temperaturen, som i sin tur beror på kabeldiameter, förspänning och kabelsystem. Avslutningsvis utfördes en modalanalys som visade på att Snedkabel Byggnaden klassificeras som en styv byggnad enligt riktlinjer från Council on Tall Buildings and Urban Habitat. Ytterligare studier på strukturen kan genomföras inom olika områden, då detta är en förstudie på byggnaden. Exempelvis på vidare forskning är att ta hänsyn till materialens ickelinjäriteter, byggnadens dynamiska respons samt samverkan mellan byggnad och grund.

Full textAbstract:
The objective of this study is to investigate the accuracy and computational efficiency of two commonly used formulations for performing the geometrically nonlinear thermal analysis of plane framed structures. The formulations considered are the followings: the Beam-Column formulation and the updated Lagrangian version of the finite element formulation that has been adopted in the commercially well-known software SAP2000. These two formulations are used to generate extensive numerical data for three plane frame configurations, which are then compared to evaluate the performance of the two formulations. The Beam-Column method is based on an Eulerian formulation that incorporates the effects of large joint displacements. In addition, local member force-deformation relationships are based on the Beam-Column approach that includes the axial strain, flexural bowing, and thermal strain. The other formulation, the SAP2000, is based on the updated Lagrangian finite element formulation. The results for nonlinear thermal responses were generated for three plane structures by these formulations. Then, the data were compared for accuracy of deflection responses and for computational efficiency of the Newton-Raphson iteration cycles required for the thermal analysis. The results of this study indicate that the Beam-Column method is quite efficient and powerful for the thermal analysis of plane frames since the method is based on the exact solution of the differential equations. In comparison to the SAP2000 software, the Beam-Column method requires fewer iteration cycles and fewer elements per natural member, even when the structures are subjected to significant curvature effects and to restrained support conditions. The accuracy of the SAP2000 generally depends on the number of steps and/or the number of elements per natural member (especially four or more elements per member may be needed when structure member encounters a significant curvature effect). Succinctly, the Beam-Column formulation requires considerably fewer elements per member, fewer iteration cycles, and less time for thermal analysis than the SAP2000 when the structures are subjected to significant bending effects.

As últimas quatro décadas foram importantes para o desenvolvimento da malha rodoviária brasileira. O sistema de rodovias do país recebeu incentivos financeiros à sua expansão e diversas soluções estruturais para pontes e viadutos foram criadas a fim de atender à demanda de infraestrutura. Em contrapartida, a carência de programas de manutenção preventiva tem causado um crescimento significativo no número de estruturas desse tipo que se encontra em estágio avançado de deterioração. Dessa maneira, esta dissertação propõe um plano de monitoramento de curta duração para monitorar o comportamento estrutural de uma ponte rodoviária curva de concreto armado já em serviço. A partir da revisão do estado-da-arte no assunto, são apresentados os tipos de monitoramento, as possíveis grandezas a serem monitoradas e as ferramentas para medi-las, assim como suas vantagens e desvantagens. A fim de avaliar estruturalmente o comportamento da ponte e auxiliar no plano de monitoramento, uma hierarquia de seis modelos numéricos é desenvolvida. Então, o plano de monitoramento proposto é aplicado na ponte sob estudo para aquisição de dados, que são posteriormente tratados e confrontados com os dois modelos numéricos mais complexos da hierarquia em um processo de análise e calibração desses modelos. Dessa análise, é possível mostrar a representatividade dos modelos desenvolvidos e a relação entre complexidade do modelo, número de parâmetros adotados para a representatividade da estrutura e convergência de resposta.The last four decades were important for the development of the Brazilian highway system. Investments were made on the expansion of highways and many structural solutions for bridges and viaducts were developed in order to attend the countrys demand. In contrast, the lack of preventive maintenance programmes has caused a significant increase in the number of those structures found in advanced deterioration stage. Thus, this thesis aims to suggest a short-term monitoring plan to monitor the structural behaviour of a curved highway concrete bridge in service. From studies on state-of-the-art in monitoring, it is presented its types, magnitudes and tools to measure them structures, as well as their advantages and disadvantages. In order to assess the structural behaviour of the bridge and support the monitoring plan, a hierarchy of six numerical models is developed. Then, the proposed monitoring plan is applied to the bridge under study for data acquisition. Afterwards, this data is processed and compared with the two more complex numerical models of the hierarchy in a process of analysis and calibration of these models. From this analysis, it is possible to show the representativeness of the developed models and the relationship between model complexity, number of parameters and convergence.

Full textAbstract:
Over the last decade, six major earthquakes that occurred in Turkey dramatically demonstrated the poor performance of the buildings that were designed and constructed far from Turkish seismic code&rsquos requirements. The Marmara region, where most of the population and industry is located, is in the active seismic zone. With the rising cost of damages due to earthquakes, the necessity of the cost-benefit analysis for various rehabilitation strategies used in existing buildings has become a major concern for the decision makers who are in the position of making decisions on the building rehabilitation This study evaluates the performance of two different rehabilitation strategies applied to two five-story reinforced concrete buildings and assesses their cost-benefit analyses. These buildings were chosen to be representative of the typical residential To carry out the structural analysis of the buildings, three-dimensional models of the buildings were developed using SAP2000 [6]. Two alternative strengthening methods, insertion of reinforced concrete shear walls and application of Carbon Fiber Reinforced Polymers (CFRP) on hallow clay tile infill walls, were used for both of the buildings. While modeling infill walls strengthened with CFRP, two specific modeling attempts proposed by the researchers at Middle East Technical University were used. Pushover analyses were performed to evaluate seismic performance of the buildings. The Life Safety criterion was chosen as the rehabilitation objective. The global and component response acceptability limits were checked and the cost-benefit analysis was performed in order to determine the most attractive rehabilitation alternative. The results and comparisons given here illustrated that strengthening with shear wall had the most significant improvement on the seismic performance and cost effectiveness of the case study buildings. Outcomes of this study are only applicable to the buildings employed here and are bound by the assumptions made, approximations used and parameters considered in this study. The findings cannot be generalized for the buildings rehabilitated with CFRP due to lack of the consistent models for CFRP application. More research needs to be conducted to provide solid guidelines and reliable models applicable to the CFRP rehabilitated infill walls.

L'elaborato propone un metodo per la modellazione tridimensionale di interi edifici in muratura, con lo scopo di valutare le performance sismiche, mediante il programma di calcolo SAP2000. La metodologia proposta consente la modellazione di pareti in muratura simulandone il comportamento non lineare sotto azioni agenti nel piano ed allo stesso tempo permette di considerare la ripartizione delle azioni verticali e soprattutto orizzontali che avviene tra le pareti, dovuta alle zone di connessione, ai solai ed alla loro rigidezza a taglio nel piano. Per lo sviluppo del metodo di modellazione è stato utilizzato un edificio molto semplice. Successivamente la metodologia è stata applicata ad un caso più realistico sul quale si sono fatte anche considerazioni riguardo i diversi comportamenti della struttura in funzione della rigidezza dei solai.

This chapter presents the nonlinear static methods of analyses for seismic design of structures considered by Eurocode 8. The first method is the nonlinear pushover procedure, which is based on the N2 method. The second method is the classical nonlinear time history analysis. The first method is studied in more detail, because the second method is a well-established procedure whose only drawback is the time necessary for the analyses. Nonlinear solvers and procedure in program Z_Soil are described. After a simple nonlinear SDOF application, a test-bed application consisting of an existing two-story reinforced concrete building in Bonefro, Italy is used to compare the two nonlinear procedures. The selected building is representative of typical residential building construction in Italy in the 1970s and 1980s. The aim of this chapter section is to compare 2D and 3D procedures implemented in Z_Soil software. The second example is a 14-story reinforced concrete building designed according to the Algerian code using Sap2000 software.

This chapter includes application of recent research on the repair and strengthening of historical structures and provides a structural assessment of five historical mosques in Albania. Apart from visual inspection, terrestrial laser scanner (TLS) data are used to analyze the historical structures. The FEM analysis conducted in SAP2000 aims to investigate the structural behavior of the undamaged model under static and dynamic loads. Stress concentration and mode period results have a considerable difference, which highlights earthquake vulnerability and changes the strategy of possible retrofitting. As a result, possible practical solutions for the structural problems based on previous research and enhancement of the existing structural resistance are suggested.

According to the seismic risk assessment results presented in the Final Safety Analysis Report (FSAR) for a nuclear power plant in Taiwan, the failure of Residual Heat Removal (RHR) piping system occurs in both of the two accident sequences with the highest contributions for core damage. The seismic performance of RHR piping system depends on the capacity of its components, such as supports, flanged joints and reducers. For the need of seismic response-history analysis of RHR piping systems, we developed detailed numerical models of flanged joint and reducer using finite element analysis software (ABAQUS and SAP2000). The proposed finite element models were verified by the experimental results. The pure bending tests with four-point cyclic loading were conducted for sample flanged joint and reducer to investigate their mechanical behaviors. The displacement and rotation responses identified from the tests are in good agreement with the results of numerical analysis. A preliminary simplified model of flanged joints was also proposed in this study to improve the efficiency of numerical analysis for RHR piping system.

The objective of this study is to build a credible numerical model using SAP2000 for fragility analysis of RHR piping system, and to establish the load pattern of a cyclic loading test to identify the seismic vulnerability of the system. The RHR piping system selected for test and numerical analysis is duplicated from a part of the RHR system in a nuclear power plant (NPP) in Taiwan, and this part is distributed between the floor of the reactor building (RB) to the wall of the reinforced concrete containment vessel (RCCV) of the sample NPP. The numerical model for the sample RHR piping system was developed, and the nonlinear response-history analysis was conducted using input motions compatible with the floor response spectrum at the anchor points of the sample piping system subjected to Safe Shutdown Earthquake (SSE). Based on the distribution of resultant inertial forces and the responses at critical locations of the piping system under SSE, the magnitudes and locations of the equivalent concentrated static loads were determined and used in the pushover analysis to estimate the capacity of the RHR piping system. The numerical results will be verified by the aforementioned cyclic loading test. More studies are on the way including shaking table test and fragility analysis for the sample piping system to further identify the seismic performance and risk of the system.

The purpose of this work is to examine a three-legged jacket tower support system subjected to wave loading. To this end, linear as well as nonlinear wave scenarios are investigated. The structure was designed for offshore wind turbines installed in intermediate water depths. The phenomenon of the wave-structure interaction is examined experimentally with a 1:18 scaled model as well as numerically with the use of Finite Element Model (FEM). The structural calculations were performed using the structural analysis software SAP2000, which was enhanced by a special programming interface that was developed to calculate the wave loading and to directly apply the wave loads on the structural members. The FEM model in combination with the key parameters that are taken into account, provides a good correlation with the experimental results. The wave theories of Airy and Stokes 5th are employed for the calculation of the wave particle kinematics. The resulting wave forces are examined both in the frequency and in the time domain.

Nowadays it becomes trend in studying of dynamic behavior on complex structure. Model updating is one of the tools developed for verifying accuracy of finite element models. In this paper, method for computing model updating on finite element model and effective the experimental modal analysis of structural systems is developed. The identification method developed in this study is based on time-domain system identification numerical techniques. The case study considered in this work is a 3D printed structure that be modeled as a two-story shear building system with irregular torsion. A preliminary numerical model of the two-story shear building system is developed by using SAP2000 and the experimental modal parameters data are collected in the laboratory buy some test then are modeled by Artemis modal pro. After obtaining the results from numerical modal and experimental modal, it was brought to FEMtools software to improve the match between the dynamic properties of an initial structure and the experimentally estimated modal data for updating. After updating, it’s shown that optimization was done, that some unknown material parameters (such as mass density and young modulus) of materials and/or boundary conditions were optimized by FEMtools Optimization that provides the possibility to perform design optimization on updated finite element models.

<p>Structural optimization of arches under multi-load cases is faced. For this aim, truss-type arches are to be considered because, under different load cases, bending effects unavoidably occur in single-rib arches shaped under one load case only. An effective procedure for simultaneous topology, shape and size optimization of truss-arches under multi-load cases is proposed. For this aim, shape, size and topology variables are assembled in a unique set of variables that are simultaneously optimised by the optimization algorithm. For given Pratt-type brace pattern, different topologies have been considered by varying the node number, whereas Cubic Rational Bézier curves have been used to shape the arch chords. Optimum diameter and thickness of the circular hollow section members was also obtained. Optimization was performed in MATLAB environment, by applying a modified Differential Evolution (DE) algorithm implemented with a Constraint Domination Selection (CDS) criterion. For each design variable vector, a FEM analysis of the resulting model has been carried out by SAP2000 to evaluate the objective function value (volume) feasibility of each design variable vector in terms of structural performance. Optimal solutions have been found and compared, providing useful suggestions to consider as guidelines in truss-arche design.</p>

Full textAbstract:
The purpose of this work is to highlight the importance of considering the actual nonlinear dynamic response for the analysis and design of fixed deep water platforms. The paper highlights the necessity of applying dynamic analysis through the comparison with the results obtained by the authors by applying static nonlinear analysis on the structure under examination. The example treated in the context of the present paper is a compliant tower, set-up in deep water. Nonlinearities are considered both for the calculation of the wave loadings and the structural analysis. The wave loading is based on linear random wave theory and comparisons are provided with the steady wave theories, Airy and Stokes 5th. The former solution is based on the most probable shape of a large linear wave on a given sea-state; the auto-correlation function of the underlying spectrum. On the other hand, in the field of structural analysis, two cases are considered for comparison, static analysis and time history dynamic analysis. For both types of analysis, two sub-cases are considered, a case in which geometric nonlinearity and nonlinearities related to the modelling of the soil are considered and a case in which the corresponding linear theories are employed (reference cases). The structural calculations were performed using the well-known structural analysis software SAP2000, which was enhanced by a special programming interface that was developed to calculate the wave loading and to directly apply the generated loads on the structural members. The results show that the consideration of the particle velocities associated with the linear random wave theory in the wave loading lead to significant differences with respect to the steady wave theories in terms of the displacements and stresses of the structure. Moreover, irrespectively of the adopted wave theory, the nonlinear analyses lead to significant discrepancies with respect to the linear ones. This is mainly associated with the nonlinear properties of the soil. Another source of discrepancies between the results of static and dynamic analyses stems from the change of the effective natural frequency of the structure when nonlinearities are considered.

Full textAbstract:
<p>The Stovner Tower forms part of an activity park in the Stovner district of Oslo. The tower, providing a serpentine walkway through the treetops with a maximum height of 15m, is designed to be universally accessible. The route is based on a series of straight lengths connected with abrupt changes of direction. The 2m wide walkway has an overall length of 270m with a constant 1:15 slope. There are four intermediate horizontal platforms intended as relaxation and viewing areas, each one with different sizes. The principal deck structure is steel, formed from a central tube with a diameter of 762mm. The tube is made up of a series of 2m long straight segments which form the walkway change of direction. Steel cantilever ribs are located at 1.5m centres to support both the solid timber decking and the 1.3m high guardrail. The central steel tube is supported at multiple locations by tripod columns formed from GL32c glulam timber sections varying from 200x200mm to 350x350mm. The timber columns are anchored to the bedrock located close to the surface in this area. Steel walkway sections were shop welded in transportable lengths with bolted on- site connections. Timber to steel connections were also bolted. Steel is painted for corrosion protection. All timber, both solid C24 for decking and glulam columns, is treated for external use. A 3D SAP2000 FE model was used for verifications including a buckling analysis for the slender timber columns and a modal analysis to check for frequencies that would make the structure susceptible to pedestrian-induced vibrations.</p>

Abstract Based on recent earthquakes experiences in Taiwan, losses do not necessarily result from damages of building structures but non-structural components. For instance, the leakage of the fire protection sprinkler systems in hospitals during small earthquakes could results in shortage of medical function and fire protection, and malfunction and repairs of medical equipment. The break of sprinkler systems caused by strong earthquakes could even harm the life safety. Taking a medium-scale hospital as an example, this research aims to conduct a simplified seismic evaluation method to improve seismic performance of the fire protection sprinkler system in critical buildings. The content of this research is summarized below: 1. Numerical analysis of the sample sprinkler piping system: a detailed numerical model of the fire protection sprinkler system in the sample hospital was established with SAP2000 v.20 software. Proper parameters to simulate the threaded joint of piping and the gap between adjacent partition walls or ceiling systems were proposed and verified by the results of component tests and shaking table tests. Ambient vibration tests in the sample hospital were conducted with velocimeters to clarify the structural characteristics of the building structure and the sprinkler piping system. 2. Fragility analysis of sprinkler piping systems: seismic fragility curves the fire protection sprinkler system in the sample hospital were conducted according to a mount of detailed analysis results and verified by the real damage state under Jiaxian earthquake. The effects of engineering demand parameters and categories of ground motion on fragility results are discussed for three types of failure modes. 3. Simplified seismic evaluation method for sprinkler piping systems: according to the results of shaking table tests and detailed analysis, a reliable simplified evaluation method was established to predict seismic behavior of typical sprinkler piping systems in hospitals by the information obtained from in-situ survey. The conservative level and accuracy of simplified evaluation results were verified by comparing the results of fragility analysis of numerical model and simplified evaluation.
