Dynamics of Structures (Prentice-hall International Series in Civil Engineering and Engineering Mechanics)

Product Information

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. As the number of degrees of freedom of a structure increases it very quickly becomes too difficult to calculate the time history manually – real structures are analysed using non-linear finite element analysis software. The concept of earthquake response spectrum and design spectrum will be explained and their utility in the seismic analysis and design of structures would be discussed. This action can be in the form of load due to the weight of things such as people, furniture, wind, snow, etc. He has been responsible for the development and teaching of courses in structural engineering, structural dynamics, and earthquake engineering.

Professor Chopra serves as a consultant on earthquake engineering problems to numerous governmental and private organizations. Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc. Although this is too simplistic to apply to a real structure, the Heaviside step function is a reasonable model for the application of many real loads, such as the sudden addition of a piece of furniture, or the removal of a prop to a newly cast concrete floor.

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. He has extensive experience in conducting large scale experiments to characterize static and dynamic behavior of structures. No prior knowledge of structural dynamics is assumed and the manner of presentation is sufficiently detailed and integrated, to make the book suitable for self-study by students and professional engineers. Most purchases from business sellers are protected by the Consumer Contract Regulations 2013 which give you the right to cancel the purchase within 14 days after the day you receive the item.

Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course. Graphs of dynamic amplification factors vs non-dimensional rise time ( t r/ T) exist for standard loading functions (for an explanation of rise time, see time history analysis below). A modal analysis calculates the frequency modes or natural frequencies of a given system, but not necessarily its full-time history response to a given input. His expertise is in the advanced software programming, in the seismic design of reinforced concrete buildings and in the F. 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.This book lays the foundation of knowledge that will allow a better understanding of nonlinear phenomena that occur in structural dynamics. Particularly, this publication shows the solution of the equation of dynamic equilibrium for structure with nonlinear time‐independent materials (plasticity, damage and frequencies evolution), as well as those time dependent non‐linear behavior materials (viscoelasticity and viscoplasticity).
