DYNAMIC TEST ON PARTIALLY REINFORCED CONVENTIONAL CEILINGS AND SIMULATION ANALYSES

Abstract

In recent years, the collapse of ceilings due to earthquakes has become a serious problem. The authors have proposed the reinforcing method to improve the aseismic performance of conventional ceilings. The proposed method employs the partial reinforcement only around the braces of ceilings, and can be easily and economically applied. The shaking table tests of the partially reinforced ceilings were carried out to investigate dynamic characteristics. The analytical model of the reinforced ceilings is proposed based on the static cyclic loading tests and the simulation analyses were carried out to show the effectiveness of the analytical model.
