Abstract

In this paper, analytical results from 3D temporal characteristics of the responses of an RC frame building subjected to both a large aftershock and the main shock of Wenchuan M_s 8.0 earthquake are presented. The ground motion records from the main shock were obtained from three nearby stations. The acceleration records were analyzed in terms of instantaneous tangential acceleration a_T, normal acceleration a_N, Euclidean norm of acceleration vector |a|, velocity vector |ν|, displacement vector |& nu;|, temporal curvature k, k_t, and temporal torsion γ and γ_t. Results of the kinematic relationship between the above factors and some additional in depth information obtained from extensive analyses are provided and discussed.
