Equivalent Static Method and Response Spectrum Method in Seismic Analysis -
In seismic analysis of structures, Equivalent Static Analysis and Response Spectrum Analysis are two methods that analyze the elastic behavior of a structure, in other words, the behavior of the structure without considering any yields (plastic hinges). But how do they differ? Equivalent Static Analysis is the simplest most straightforward analysis, which will either suffice for simpler structures or you need to do anyway to get a feel for how would it be if the loading was static and the structure remained elastic. This method is good for short period, stiffer structures such as short buildings. Here the building is not tall enough for instance, to meaningfully produce higher vibration […] Read More
