چکیده

Abstract

Modern seismic design codes stipulates a behavior factor (q-factor) to reduce the earthquake loads which the structure is to be designed for. This is in account for the inelastic behavior of the structure when subjected to severe earthquakes. Inelastic dynamic analysis consumes long time in the interpretation of its results. A popular and simple method for studying the nonlinear response of the structure is pushover analysis. Static type of pushover analysis is to be used in this research work where the loads consist of permanent gravity loads and incremental horizontal forces at each storey level. Capacity curves (base shear versus story total drift) obtained from static pushover analysis using a commercially available software called SeismoStruct (SeismoSoft 2014) are used for the calculation of some seismic demand parameters such as behavior factor, q, overstrength factor, , and ductility based reduction factor, Rµ. Four reinforced concrete moment-resisting frames each of 7, 5 and 3 stories are used in the analysis. The research work proved the efficiency of the static pushover analysis in studying the nonlinear behavior of structures and that the suggested behavior factor (q) by the Eurocode 8-Part 1 (Eurocode 8 Committee 2003) for non-dissipative structures presents an acceptable lower limit.
