Abstract
Based on the oscillation response theory of free-standing equipment,the initial condition for occurrence of oscillation and the critical condition for falling down of free-standing equipment under seismic excitations are analyzed.The calculation method for seismic oscillation response analysis is presented.The differential equation of oscillation of free-standing equipment under seismic excitations is resolved by Runge-Kutta algorithm,the software is developed,and the reliability of the software is validated by numerical illustrations.The oscillation response characteristics of free-standing equipment are investigated by using the developed software,and the oscillation response time history and some reasonable results of free-standing equipment under seismic excitations are also obtained.
