Understanding Response Spectrum — Lesson 3

This lesson covers the concept of response spectrum for different types of shock waves, focusing on the tangent type of excitation. It explains how to calculate the peak displacement using the response spectrum for displacement, velocity, and acceleration. The lesson also discusses the importance of the response spectrum in earthquake regression design and how it can be used to determine the acceleration a structure may experience due to ground motion. The lesson further elaborates on the development of response spectrum for pulse wave and its application in seismic motion or building subjected to ground acceleration. The lesson concludes with an illustrative example of a cantilever pool subjected to a half sine pulse wave.
