Abstract :
Nonlinear Time History (NTH) analysis is currently the most reliable method for estimating structural behavior. Considerable computational demand and complexity of this method may cause difficulty for its routine practical application. Based on the Methodology of Endurance Time (ET) method, it can estimate the nonlinear response of structures with a much lower computational cost. In this research, the reliability of the ET method in the analysis of concrete moment frames will be discussed. The results of the ET method are compared with those acquired from the NTH method by considering some energy Engineering demand parameters(EDP) like base shear roof displacement. Furthermore, the accuracy of this method for estimating damage in structures was evaluated by considering inter story Drift, Park-Ang, and Bozorgnia-Bertero models as samples of damage indices. It is observed that the nonlinear dynamic response of structures and damage indices can be estimated by the ET method with reasonable accuracy.
