VERIFING OF SIMPLIFIED METHODS FOR SEISMIC ASSESMENT OF STEEL MOMENT FRAMES BY NONLINAER STATIC AND DYNAMIC ANALYSIS

The major guidance documents for seismic assessment of existing buildings are ASCE 41-06 inUS, and NZSEE recommendations in New Zealand.All of these guidelines have provided simple criteria in terms of simplified rehabilitations on the assessment of existing buildings. The present study is focused on verifying the results of the simplified methods which is used by NZSEE and ASCE 41-06 in assessment of moment frames. For this, three different special moment steel frames are assessed under these two guidelines and the accuracy of the results are checked with the nonlinear static and dynamic analysis.
