Simulation of Oscillation Response of Free-Standing Object under Earthquakes

Abstract:

To protect free-standing object,a rectangular object is taken as example and by SIMULINK technique its oscillation response under earthquakes were studied.Based on static and dynamic balance theories,oscillation conditions as well as motion equations of the free-standing object under earthquakes were deduced;Based on SIMULINK model,simulation analysis on the object under both level and vertical earthquakes were carried out,parameters such as initial conditions,earthquake intensity and ratio of width of the object against its height (B/H) and so on were discussed.Results show that under earthquakes oscillation conditions of the object relate closely to B/H,earthquake intensity and friction coefficient between object and its base;Under earthquakes oscillation response of the object is sensitive to initial conditions,and the response becomes more serious under less B/H or larger earthquake intensity conditions.Besides, SIMULINK technique can effectively simulate oscillation response of free-standing object under earthquakes,which proves the technique useful.
