Study for the Dynamic Response of Rubber Concrete RC Slab

Abstract

The tradition RC building slab system is very rigid so the vibration and the will induce large noise often creates puzzle of the user. The slab vibration also will reduce the production fine proportion for high tech factory. So we must to enhance the RC slab energy absorbing capacity to reduce RC floor vibration. The rubber material has very good elasticity and energy absorbing capacity so is widely applied in many daily items. But the easy consuming characteristic will increase the waste process problem. If we can apply the high elasticity property in recycle rubber to RC slab so we can reduce the waste pollution and slab vibration behavior in the same time. The complex RC slab real behavior must be measure from test result. In this paper we want to get the dynamic behavior by pedestrian loading for rubber concrete RC slab by laboratory test. By the test results we can found the 5% rubber concrete will concentration to 7.2 Hz.
