The static and quasi-static behaviors of concrete have been the subject of so many works that we often consider that they are quite well known and mastered as far as modeling with a view to structure calculations is concerned. However, the same is not true of concrete’s dynamic behavior, because of the complexity of the tests needed to reach pertinent loading rates.
This book introduces and explains all aspects of earthquake-resistant design of structures. Designed as a textbook for undergraduate and graduate students of civil engineering, practising engineers and architects will also find the book equally useful.
It has been assumed that the reader is well acquainted with structural analysis, structural dynamics, and structural design.
The design of earthquake-resistant structures is an art as well as science. It is necessary to have an understanding of the manner in which a structure absorbs the energy transmitted to it during an earthquake.
The book provides a comprehensive coverage of the basic principles of earthquake-resistant design with special emphasis on the design of masonry, reinforced concrete, and steel buildings. The text is focussed on the design of structural and non-structural elements in accordance with the BIS codes.

The main aim of this book, published at the time Eurocode 8 is starting its course as the only seismic design standard in Europe, is to support its application to concrete buildings – the most common type of structure – through education and training.

This book is an expanded version of the earlier (first edition) text, Earthquake Engineering —Damage Assessment and Structural Design, here called EE-DA&SD.
Every chapter of the first edition has been altered and enlarged and new chapters have been added to include work done by the author and some of his graduate students, following the publication of EE-DA&SD.
Some remarks concerning the modus operandi of the two texts may be in order. In accordance with currently accepted methods of scientific inquiry, the procedures used in EE-DA&SD and in this bode for developing the rational earthquake engineering theory.

The vast devastation of engineered systems and facilities during the past few earthquakes has exposed serious deficiencies in the prevalent design and construction practices. These disasters have created a new awareness of disaster preparedness and mitigation.
With increased awareness came the demand of learning resource material which directly addresses the requirements of professionals without any circumlocution. While the recommended codes of practice for earthquake resistant design do exist but those only specify a set of criteria for compliance. These design codes throw little light on the basic issue of how to design.
The problem! Jl becomes more acute as students graduate with degrees in civil/structural engineering without any exposure to earthquake engineering in most of the universities/institutes. The short-term refresher courses routinely offered by various institutes and universities for professionals achieve little more than mere familiarization with the subject matter.
This chapter provides a basic understanding of earthquakes, by first discussing the causes of earthquakes,
then defining commonly used terms, explaining how earthquakes are measured, discussing the distribution
of seismicity, and, finally, explaining how seismicity can be characterized.
Earthquakes are broad-banded vibratory ground motions, resulting from a number of causes including tectonic ground motions, volcanism, landslides, rockbursts, and man-made explosions.
Of these, naturally occurring tectonic-related earthquakes are the largest and most important.
These are caused by the fracture and sliding of rock along faults within the Earth’s crust. A fault is a zone of the
earth’s crust within which the two sides have moved — faults may be hundreds of miles long, from one to over one hundred miles deep, and are sometimes not readily apparent on the ground surface.

The main aim of this book is a collection of data which is useful in understanding the state-of-art technology and its application to new topics. Understanding the fundamental issues is important because practice makes use of many assumptions, hypotheses, and ways of thinking.
It has been my policy to show reasons why practice employs those ideas by showing experimental and field backgrounds. This idea does not change even today. Collecting background information is not very easy for an individual person.
It is necessary to read many publications; some were published in the first half of the 20th Century, and others in domestic publications. Not being impossible, this information collection is firstly a time-consuming business.
Secondly, access to old publications may not be easy to everybody. I am therefore attempting in this book to collect information as much as possible so that the new generation of readers can save time in studying.

This book gathers 23 papers by top experts from 11 countries, presented at the 3rd Houston International Forum: Concrete Structures in Earthquake.
Designing infrastructures to resist earthquakes has always been the focus and mission of scientists and engineers located in tectonically active regions, especially around the “Pacific Rim of Fire” including China, Japan, and the USA.
The pace of research and innovation has accelerated in the past three decades, reflecting the need to mitigate the risk of severe damage to interconnected infrastructures, and to facilitate the incorporation of high-speed computers and the internet.
The respective papers focus on the design and analysis of concrete structures subjected to earthquakes, advance the state of knowledge in disaster mitigation, and address the safety of infrastructures in general.
