In performance based seismic design, the design index can reflect the structural and non-structural damage that may occur during earthquake ground motion excitations. It is important to get more understandings of the behaviors of the responses of structural systems in order to become design codes for using in practice. In this study, it focuses on two kinds of typical reinforced concrete buildings with three different elevations in Taiwan. All of them are designed by using Taiwan building codes. Non-linear time history analysis of a detailed analytical model subjected to a suite of representative site-specific ground motions is chose for the estimation of these seismic demands. The focus is on a statistical evaluation of the seismic response of structural systems. Finally, it gets comprehensive understandings of the inelastic dynamic response of multi-degree-of-freedom structural systems by means of several seismic demands. Then a simplified process that provides quick and reasonable estimates of seismic demand for the MDOF systems is proposed. Also the relationships between the MDOF systems and their corresponding SDOF systems are established.Contents 誌謝 i 摘要 ii Abstract iii Contents iv List of Tables vi List of Figures vii Chapter 1 Introduction 1 1.1 Motivation for this study 1 1.2 Literatures Review and Background 2 1.3 Objectives and Organization of the Thesis 3 Chapter 2 Methodology 8 2.1 Nonlinear Analytical Model 8 2.1.1 Bilinear Systems 9 2.1.2 Pinching Systems 11 2.1.3 Stiffness-Degrading, and Load-Deteriorating Systems 12 2.2 Nonlinear Parameter Setting 15 2.2.1 Cyclic Loading Tests of two-story RC Frames 15 with different non-structural walls 15 2.2.2 Comparison between Simulations and the Tests 16 2.2.3 The Limitations of the Nonlinear Model 17 2.3 Typical RC Building in Taiwan 18 2.3.1 Modified Shear Building Model 18 2.3.2 Equivalent SDOF System 21 2.4 Summary and Discussion 22 Chapter 3 Seismic Demands 46 3.1 Deformation demands 47 3.1.1 Roof displacement demands 47 3.1.2 Interstory displacement demands 48 3.1.3 Story ductility demands 49 3.2 Strength demands 49 3.2.1 Base shear demands 50 3.2.2 Story shear demands 50 3.2.3 Story overturning moment demands 50 3.3 Energy demands 51 3.3.1 Hysteretic energy (HE) demands 51 3.3.2 Distribution of hysteretic energy demands over height 52 3.3.3 Normalized Hysteretic Energy 52 3.4 Summary and Discussion 53 Chapter 4 Case Study for Frames and Walls 54 4.1 Input Strong Ground Motions 54 4.1.1 Rock Site Records 54 4.1.2 Near Fault Records 55 4.1.3 Target Spectrum and Corresponding Fitted Earthquakes 55 4.2 Moment Resisting Frame Structure 58 4.2.1 Deformation demands 58 4.2.2 Strength demands 60 4.2.3 Energy demands 61 4.2.4 Implications for design 62 4.3 Wall structure 63 4.3.1 Deformation demands 64 4.3.2 Strength demands 65 4.3.3 Energy demands 66 4.3.4 Implications for design 67 4.4 Summary and Discussion 67 Chapter 5 Conclusions and future works 127 5.1 Summary and Conclusions 127 5.2 Suggestions for Future Research 129 References 131 Appendix A Drift, Ductility and Shear responses of Pure Frames 133 Appendix B Drift, Ductility and Shear responses of Wall Frames 151 簡歷39031120 bytesapplication/pdfen-US性能設計法地震需求非彈性多自由度系統seismic demandsinelastic MDOF systemsperformance-based designthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/50422/1/ntu-93-R91521220-1.pdf
