Earthquake action is the main external factor which influences long-term safe operation of civil\udconstruction, especially of the high-rise building. Applying time-history method to simulate earthquake response\udprocess of civil construction foundation surrounding rock is an effective method for the anti-knock study of\udcivil buildings. Therefore, this paper develops a civil building earthquake disaster three-dimensional dynamic\udfinite element numerical simulation system. The system adopts the explicit central difference method.\udStrengthening characteristics of materials under high strain rate and damage characteristics of surrounding rock\udunder the action of cyclic loading are considered. Then, dynamic constitutive model of rock mass suitable for\udcivil building aseismic analysis is put forward. At the same time, through the earthquake disaster of time-history\udsimulation of Shenzhen Children’s Palace, reliability and practicability of system program is verified in the\udanalysis of practical engineering problems

Time-history simulation of civil architecture earthquake disaster relief- based on the three-dimensional dynamic finite element method
