About this book

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.

Chapter 1. Introduction

Buildings are the major structures that are exposed to damage when earthquakes are triggered. This damage can cause losses including lives and properties. Building damage is the main source of seismic loses during earthquakes. To solve this problem, fragility curves were introduced by researchers to serve as one of main tool in assessing damage and loss during earthquakes.

Chapter 2. Fragility Curves

In these book, fragility curves are defined as the probability of reaching or exceeding a specific damage stateDamage state under earthquake excitation. The fragility curves are established to provide a prediction of potential damage during an earthquake. The fragility function is also directly used to reduce damage cost and loss of life during a seismic event. Therefore, fragility curves can be used as a decision-making tool for both pre- and post-earthquake situations. Moreover, these curves may help develop future local code provisions.

Chapter 3. Moment-Resisting Frames (MRFs)

In this section, six sets of model moment-resisting framesMoment-Resisting Frames (MRF) (MRF) were analyzed with different types of geometry (regularRegular frames and irregular framesIrregular frames), material, and heights. These frames abide by the Eurocodes (EC).

Chapter 4. Performance of MRFs Due to Nonlinear Analysis

Pushover analysis (POA) Pushover analysis (POA) was carried out on six different types of frames. In this analysis, lateral load acts as the main role in evaluating the structure performance according to the pushover analysis. In this analysis, as suggested by Eurocode 8Eurocode 8 (BSI in Eurocode 8: design provisions for earthquake resistance of structures: part 1-1, general rules—seismic actions and general requirements for structures. British Standards Institution, London, 2004), the triangle lateral load was applied to perform the analysis.

Chapter 5. Closing Remarks

The purpose of this book is to develop fragility curvesFragility curves for regular and irregular framesIrregular frames. Regular and irregular frames based on concrete (MRCF) and steel frames (MRSF) Steel frames (MRSF) for low-, mid-, and high-rise were designed based on Eurocode 2Eurocode 2, Eurocode 3Eurocode 3, and Eurocode 8Eurocode 8. The pushover analysis (POA) Pushover analysis (POA)and incremental dynamic analysisIncremental Dynamic Analysis (IDA) (IDA) were performed by using the SAP2000 software. For the dynamic analysis, three sets of near-field (NF) ground motionNear-field (NF) ground motion and far-field (FF) ground motionFar-field (FF) ground motion were used. Besides, the performance of regular and irregular framesIrregular frames due to static and dynamic load was evaluated and included in this book.
