Sliding Response of Free-Standing Cultural Relics under Earthquakes by Simulation

Abstract:

Article Preview

To protect cultural relics,sliding response of free-standing museum cultural relic under earthquakes was studied by SIMULINK technique.By hypothesis that shape of cultural relic was rectangle, under earthquakes its sliding conditions were analysed,its motion equations were deduced, its response curves of displacement,velocity and acceleration were obtained,and parameters such as friction ratio between it and its base as well as peak earthquake acceleration values were discussed.Results show that slide motion of cultural relic relates mainly to friction ratio and earthquake strength;Its sliding response is more obvious with the increase of earthquake strength and decrease of friction ratio;On the other hand,by SIMULINK technique sliding response of free-standing cultural relic under earthquakes can be effectively simulated which proves the technique useful.
