Dynamics of Structures includes many topics encompassing the theory of structural dynamics and the application of this theory regarding earthquake analysis, response, and design of structures. For simple structures the basic mode shapes can be found by inspection, but it is not a conservative method. The complete modal response to a given load F( x, t) is v ( x , t ) = ∑ u n ( x , t ) {\displaystyle v(x,t)=\sum u_{n}(x,t)} . Manish Kumar is an assistant professor in the Department of Civil Engineering at IIT Bombay in Mumbai, India.

A full time history will give the response of a structure over time during and after the application of a load. Equation of motion for SDOF systems would be developed for periodic, non-periodic and arbitrary excitations. Structural analysis is mainly concerned with finding out the behavior of a physical structure when subjected to force.Sergio Oller was appointed Full Professor at the School of Civil Engineering of the Technical University of Catalonia, Barcelona, Spain in 1988, and has worked there, as well as at the International Center for Numerical Methods in Engineering (CIMNE), up to the present.

Designed for senior-level and graduate courses in Dynamics of Structures and Earthquake Engineering.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.

It is useful to know the modal frequencies of a structure as it allows you to ensure that the frequency of any applied periodic loading will not coincide with a modal frequency and hence cause resonance, which leads to large oscillations.

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. YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. A dynamic load can have a significantly larger effect than a static load of the same magnitude due to the structure's inability to respond quickly to the loading (by deflecting).
