INFLUENCE OF MASS OF GIRDERS ON REDUCTION OF IMPACT FORCE DURING COLLISION BETWEEN STEEL GIRDERS WITH SHOCK ABSORBING RUBBER

Abstract

Studied herein is an experimental study on the collision between two steel girders using shock absorbing rubber, in order to investigate the influence of mass of girders on the reduction of impact force. The mass of girders ranges from 250kg to 500kg on 3 stages. As a result, it is found the impact forces are not different even if the mass is turned over between collision girders. Consequently, it is clarified the impact force is correlation with the total mass of girders not the mass ratio.
