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 […] Read More

This is a very useful method, which is also allowed by AASHTO or bridges and ACI 318 when designing concrete bridge and building structures respectively. By making use of this method, the stresses especially in members such as deep beams can be more realistically represented. The struts here represent the imaginary compression members of a truss and ties are the imaginary tension members. We place […] Read More

We must consider earthquake loads when analyzing all members of a structural system. A structure is a whole unit, inseparable from each other. One effect on one member has effect on other members. Therefore we can not just isolate beams and say “earthquake loads are lateral so why do we analyze beams for earthquake” At the most basic level, the beams hold the columns together […] Read More
