Chopra received his Bachelor of Science degree in Civil Engineering from Banaras Hindu University, India, in 1960, the Master of Science degree from the University of California, Berkeley, in 1963, and the Doctor of Philosophy degree, also from Berkeley, in 1966. This book uses carefully-selected worked examples to instil an understanding of the theories underlying widely-used computer analysis systems and show readers how to carry out simple hand calculations in structural dynamics. Taking a different approach, Structural Damping: Applications in Seismic Response Modification considers the dynamic responses of structures with added damping devices as systems governed by the combined effect of the static stiffness, period, and damping—or "dynamic stiffness"—of the structure-device system. Equation of motion for SDOF systems would be developed for periodic, non-periodic and arbitrary excitations.

This book addresses the topic of structural dynamics, which is a branch of structural analysis devoted to the behavior of structures subjected to dynamic loads, from a theoretical and algorithmic approach. If it changes slowly, the structure's response may be determined with static analysis, but if it varies quickly (relative to the structure's ability to respond), the response must be determined with a dynamic analysis. The distinction is made between the dynamic and the static analysis on the basis of whether the applied action has enough acceleration in comparison to the structure's natural frequency. This action can be in the form of load due to the weight of things such as people, furniture, wind, snow, etc. The static displacement can be calculated with u static = F 1 , eq k 1 , eq {\displaystyle u_{\text{static}}={\frac {F_{1,{\text{eq}}}}{k_{1,{\text{eq}}}}}} .This formulation supplies additional information for higher-level supplemental damping design that current provisions may not adequately cover. For simple structures the basic mode shapes can be found by inspection, but it is not a conservative method.

Professor Chopra serves as a consultant on earthquake engineering problems to numerous governmental and private organizations. Dynamic analysis for simple structures can be carried out manually, but for complex structures finite element analysis can be used to calculate the mode shapes and frequencies. If a load is applied sufficiently slowly, the inertia forces ( Newton's first law of motion) can be ignored and the analysis can be simplified as static analysis. Designed for senior-level and graduate courses in Dynamics of Structures and Earthquake Engineering. where ω = k M {\displaystyle \omega ={\sqrt {\frac {k}{M}}}} and the fundamental natural frequency, f = ω 2 π {\displaystyle f={\frac {\omega }{2\pi }}} .

Currently, he serves as Executive Editor of Earthquake Engineering and Structural Dynamics, the journal of the International Association for Earthquake Engineering. This gives the (theoretical) time history of the structure due to a load F(t), where the false assumption is made that there is no damping. His work on seismic isolation of nuclear structures has contributed to the development of a NUREG guide on seismic isolation.

Structures would be idealized to simplified single-degree-of-freedom (SDOF) and multi-degree-of-freedom (MDOF) systems. In 2011, he has received the Fib Achievement Award for Young Engineers, sponsored by fib - the international federation for structural concrete.

A full time history will give the response of a structure over time during and after the application of a load.

For a given mode shape of a multiple degree of freedom system you can find an "equivalent" mass, stiffness and applied force for a single degree of freedom system.Rapid advances have been made during the past few decades in earthquake response modification technologies for structures, most notably in base isolation and energy dissipation systems.
