3D temporal characteristics analyses%Wenchuan earthquake%RC frame structure%aftershock
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 Ms 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 aT, normal acceleration aN, Euclidean norm of acceleration vector |a|, velocity vector |v|,displacement vector |d|, temporal curvature k, kt, and temporal torsion y and yt. Results of the kinematic relationship between the above factors and some additional in depth information obtained from extensive analyses are provided and discussed.
