COMPARISON OF DIFFRENT NON-LINEAR STATIC ANALYSIS USED FOR SEISMIC ASSESSMENT OF EXISTING BUILDING

The present study is focused on the comparison of non-linear static analysis (Pushover) which is used by two major guidance documents, the New Zealand guideline and the US ASCE 41-06, on the assessment of existing buildings currently available. The main purpose of the study is totrace the differences in the results produced by these two guidelines. For this, four different moment resisting concrete frames are assessed under these two guidelines to determine the PGA value that causes their collapse. In the next step, these are compared by their similar values which are determined from the nonlinear dynamic analysis.
