Abstract:
Based on the dynamic theory of structures, a Pushover analysis method considering strain rate effect was proposed. Firstly, Pushover analysis of the structure without considering strain rate effect was performed. Secondly, the variance of strain at the important points in the 1/4 cycle and the duration of the cycle corresponding to the top displacement Di were calculated, then the model could be modified according to average strain rates of the important points; Pushover analysis of the structure for the second time was performed, and a point(Di,Vi)in the Pushover curve could be obtained; the value of Di was changed, and many points could be got according to the method. Finally, the Pushover curve of the structure considering strain rate effect by connecting these points with smooth curve was obtained. Using a reinforced concrete model, the Pushover curve obtained by the method in the paper was compared with the result obtained by incremental dynamic analysis. Results show that the method is rational.
