COMPARISON OF THE PERFORMANCE POINT DETERMINATION APPROACHESPROPOSED IN TEC2007 AND FEMA440

40644

There are different approaches in the performance based design of the existing reinforced concrete structures, regarding the determination of the intersection point of capacity and demand curves. While the equivalent displacement approach is employed in Turkish Earthquake Code (TEC2007), a successive approximation technique based on the effective period and damping is suggested in FEMA440. Frame type and wall-frame type regular structures with different number of stories are selected to discuss the approaches on the performance point determination techniques proposed in TEC2007 and FEMA440. The resulting earthquake demands are compared with each other and also those obtained from the nonlinear time history analyses. Top displacement, base shear, relative story drift are amongst the discussed demand parameters. It is shown that for the structures considered in this study, the demands obtained from the TEC2007 procedure are more close to the nonlinear time history analyses results.
