Basics Of Structural Dynamics And Aseismic Design Damodarasamy Kavitha: A Comprehensive Book for Earthquake Engineering Students
Earthquake engineering is a multidisciplinary field that deals with the effects of earthquakes on structures and their design to resist seismic forces. It covers four major areas: structural dynamics, seismology, seismic analysis, and aseismic design. Structural dynamics is the study of the response of structures to dynamic loads, such as wind, blast, and earthquake. Seismology is the science of earthquakes, their causes, characteristics, and effects. Seismic analysis is the process of evaluating the seismic performance of structures using various methods and tools. Aseismic design is the art of designing structures to minimize the damage and loss of life due to earthquakes.
One of the books that covers all these four areas in a comprehensive and lucid manner is Basics Of Structural Dynamics And Aseismic Design Damodarasamy Kavitha, written by S.R. Damodarasamy and S. Kavitha, who are both experienced professors of civil engineering. The book was published by PHI Learning Pvt. Ltd. in 2009 and has 344 pages. It is intended for undergraduate and postgraduate students of civil engineering who want to learn the fundamentals of earthquake engineering.
The book consists of 18 chapters that cover the following topics:

The book also provides numerous solved examples, exercises with answers, diagrams, tables, graphs, and references to illustrate the concepts and theories. It incorporates the necessary codal provisions such as IS 1893:2002, IS 13920:1993 and IS 4326:1976 for seismic analysis and aseismic design. It also highlights the various new techniques in the field of earthquake engineering, such as base isolation, energy dissipation devices, seismic retrofitting, etc.
The book is well-written, well-organized, well-balanced, and well-suited for students who want to learn the basics of structural dynamics and aseismic design in a simple and effective way. It is also useful for practicing engineers who want to refresh their knowledge and skills in earthquake engineering.
One of the features of the book is that it emphasizes the practical aspects of earthquake engineering, such as the design of real structures, the use of software tools, the interpretation of seismic data, and the assessment of seismic risk. The book also includes a case study of the seismic analysis and aseismic design of a five-storey reinforced concrete (RC) frame building, which demonstrates the application of the concepts and methods discussed in the book. The case study shows how to model the structure, calculate the natural frequencies and mode shapes, perform the response spectrum analysis, design the structural elements, and check the ductility and capacity of the structure.
Another feature of the book is that it covers some of the advanced topics in earthquake engineering, such as the effects of soil-structure interaction, soil liquefaction, and dam safety. The book explains how soil properties affect the response spectra and how to account for them in seismic analysis. It also describes how soil liquefaction occurs and how to evaluate its potential and consequences. It also discusses how dams and embankments are vulnerable to earthquakes and how to design them to prevent failure and collapse.
The book is written in a clear and concise language, with a logical flow and a consistent notation. The book avoids unnecessary mathematical derivations and focuses on the physical interpretation and understanding of the phenomena. The book also provides ample references for further reading and research. The book is suitable for both self-study and classroom instruction. 29c81ba772
