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.

This books analyzes different approaches to modeling earthquake-induced structural pounding and shows the results of the studies on collisions between buildings and between bridge segments during ground motions. Aspects related to the mitigation of pounding effects as well as the design of structures prone to pounding are also discussed. Earthquake-induced structural pounding between insufficiently separated buildings, and between bridge segments, has been repeatedly observed during ground motions. The reports after earthquakes indicate that it may result in limited local damage in the case of moderate seismic events, or in considerable destruction or even the collapse of colliding structures during severe ground motions. Pounding in buildings is usually caused by the differences in dynamic properties between structures, which make them vibrate out-of-phase under seismic excitation. In contrast, in the case of longer bridge structures, it is more often the seismic wave propagation effect that induces collisions between superstructure segments during earthquakes.

Fundamentals of Earthquake Engineering: From Source to Fragility, Second Edition combines aspects of engineering seismology, structural and geotechnical earthquake engineering to assemble the vital components required for a deep understanding of response of structures to earthquake ground motion, from the seismic source to the evaluation of actions and deformation required for design, and culminating with probabilistic fragility analysis that applies to individual as well as groups of buildings. Basic concepts for accounting for the effects of soil-structure interaction effects in seismic design and assessment are also provided in this second edition. The nature of earthquake risk assessment is inherently multi-disciplinary. Whereas this book addresses only structural safety assessment and design, the problem is cast in its appropriate context by relating structural damage states to societal consequences and expectations, through the fundamental response quantities of stiffness, strength and ductility. This new edition includes material on the nature of earthquake sources and mechanisms, various methods for the characterization of earthquake input motion, effects of soil-structure interaction, damage observed in reconnaissance missions, modeling of structures for the purposes of response simulation, definition of performance limit states, fragility relationships derivation, features and effects of underlying soil, structural and architectural systems for optimal seismic response, and action and deformation quantities suitable for design. Key features: Unified and novel approach: from source to fragility Clear conceptual framework for structural response analysis, earthquake input characterization, modelling of soil-structure interaction and derivation of fragility functions Theory and relevant practical applications are merged within each chapter Contains a new chapter on the derivation of fragility Accompanied by a website containing illustrative slides, problems with solutions and worked-through examples Fundamentals of Earthquake Engineering: From Source to Fragility, Second Edition is designed to support graduate teaching and learning, introduce practising structural and geotechnical engineers to earthquake analysis and design problems, as well as being a reference book for further studies.

This report is about the disastrous 7.6 magnitude earthquake that occurred near the village of Chi-Chi in central Taiwan on September 21, 1999. More than 2,400 people were killed and 11,000 injured. Tens of thousands of residential units were damaged or destroyed, leaving more than 100,000 people homeless. Massive landslides destroyed everything in their paths, and in some remote areas, thousands of people were isolated for days. Lifelines were severely damaged or disrupted, and highways, bridges, and other infrastructure components sustained heavy damage. Damage estimates, including lost productivity, range from $20 billion to $30 billion (U.S.). This 184-page volume covers the topics of strong-motion instrumentation and data, fault-related surface deformation, soil liquefaction, landslides, performance of structures, highway bridges, lifeline performance, and emergency response and recovery. The report is the result of a cooperative effort among many engineers, scientists, and organizations.

Throughout the past few years, there has been extensive research done on structural design in terms of optimization methods or problem formulation. But, much of this attention has been on the linear elastic structural behavior, under static loading condition. Such a focus has left researchers scratching their heads as it has led to vulnerable structural configurations. What researchers have left out of the equation is the element of seismic loading. It is essential for researchers to take this into account in order to develop earthquake resistant real-world structures. Structural Seismic Design Optimization and Earthquake Engineering: Formulations and Applications focuses on the research around earthquake engineering, in particular, the field of implementation of optimization algorithms in earthquake engineering problems. Topics discussed within this book include, but are not limited to, simulation issues for the accurate prediction of the seismic response of structures, design optimization procedures, soft computing applications, and other important advancements in seismic analysis and design where optimization algorithms can be implemented. Readers will discover that this book provides relevant theoretical frameworks in order to enhance their learning on earthquake engineering as it deals with the latest research findings and their practical implementations, as well as new formulations and solutions.

An early Digest- No 53 in the First Series - was published in 1953 to encourage the manufacture and use of perforated clay bricks as opposed to the wholly solid units in general use in Great Britain at that time. The claimed advantages were mainly of benefit to the manufacturer: savings in drying and firing time, and reductions in costs of fuel, materials and transport. But some advantages were suggested for the user: lower unit cost, savings on transport to site, easier handling and laying because of lower weight, improved thermal insulation and more consistent quality. It was also claimed that perforated units would have adequate strength, resistance to rain penetration, durability and fire resistance. At the time, there was very little British experience of perforated bricks and virtually no experimental data; the advice and conclusions were, therefore, largely qualitative and based mainly on Continental practice and experience. The advantages have, however, become recognised gradually and the position now is that most bricks produced by the extrusion/wire cutting process (about 30 per cent of the total UK brick production) have some degree of perforation; typical examples are shown in Fig 1. There are now greater incentives to save fuel and conserve resources. In the light of more experimental data, this digest reviews the current situation. In this digest, a brick is considered to be perforated if it has holes passing through it, regardless of their size or number. This is not strictly in accordance with BS 3921: 1974 in which a brick is considered to be perforated when the holes passing through it exceed 25 per cent of its volume; below 25 per cent perforation, the Standard considers a brick to be 'solid' for structural design purposes.
