Seismic Fragility Assessment for Buildings due to Earthquake Excitation (SpringerBriefs in Applied Sciences and Technology)

Annotation This book presents a simplified approach to earthquake engineering by developing the fragility curve for regular and irregular moment-resisting frames based on different types of structural material, height, and ground motion records. It examines six sets of concrete and steel frames, which vary in terms of their height (3-, 6- and 9-storey) and include regular and irregular frames. Each structure frame was designed based on Eurocode 2 and 3 with the aid of Eurocode 8 for earthquake loading. The SAP2000 software was used as the main tool for the pushover analysis and incremental dynamic analysis. Readers are first provided with background information on the development of nonlinear analysis in earthquake engineering. Subsequently, each chapter begins with a detailed explanation of the collapse of the structures and the application in nonlinear analysis. As such, the book will greatly benefit students from both public and private institutions of higher, particularly those who are dealing with the subject of earthquake engineering for the first time. It also offers a valuable guide for Civil Engineering practitioners and researchers who have an interest in structural and earthquake engineering Acknowledgements 6 Contents 7 1 Introduction 9 References 10 2 Fragility Curves 11 2.1 Historical Background 11 2.2 Structural Types 18 2.3 Earthquake Records 19 2.4 Simulation Methods 27 2.4.1 Nonlinear Static Analysis 27 2.4.2 Nonlinear Dynamic Analysis 28 2.5 Performance-Based Seismic Design (PBSD) 30 2.6 Methods to Develop Fragility Curves 31 2.6.1 Expert-Based Method 31 2.6.2 Empirical Method 33 2.6.3 Analytical Method 33 2.6.4 Hybrid Method 34 References 34 3 Moment-Resisting Frames (MRFs) 39 3.1 Structural Model 39 3.2 Design Loads 39 3.3 Ground Motion Records 42 3.4 Development of Elastic Response Spectrum 43 3.5 Scaling for Ground Motion Records 44 3.6 Fragility Curve 44 References 46 4 Performance of MRFs Due to Nonlinear Analysis 47 4.1 Performance of Regular and Irregular MRF Due to POA 47 4.1.1 Capacity Curves 47 4.1.2 Plastic Hinges 49 4.1.3 Interstorey Drift 53 4.2 Performance of Regular and Irregular MRFs Due to IDA 56 4.2.1 Near-Field (NF) Ground Motion Records 56 4.2.2 Far-Field (FF) Ground Motion Records 58 4.3 Fragility Curve 60 4.3.1 Fragility Curve for Near-Field (NF) Ground Motion Records 62 4.3.2 Fragility Curve for Far-Field (FF) Ground Motion Records 68 References 72 5 Closing Remarks 73 Appendix A: Design of Regular and Irregular Moment-Resisting Concrete Frames (MRCF) 75 Appendix B: Design of Regular and Irregular Moment-Resisting Steel Frames (MRSF) 95 Bibliography 118 Index 120 Front Matter ....Pages i-viii Introduction (Fadzli Mohamed Nazri)....Pages 1-2 Fragility Curves (Fadzli Mohamed Nazri)....Pages 3-30 Moment-Resisting Frames (MRFs) (Fadzli Mohamed Nazri)....Pages 31-38 Performance of MRFs Due to Nonlinear Analysis (Fadzli Mohamed Nazri)....Pages 39-64 Closing Remarks (Fadzli Mohamed Nazri)....Pages 65-66 Back Matter ....Pages 67-114
