Influential researches of renovation on structural reliability of floor materials

YANG Ting-lian,WANG Jie-guang,LI Wen-xing,TAN Jing-he(Department of Civil Engineering,Guilin Institute of Technology,Guilin541004,China)  
After being decorated with kinds of the ornamental material such as hardwood,ceramic brick and stone material etc.on the building floor,the floor-loading will be increased to a great extend and lower the structural safety.The floor renovation of the multiplayer brick-mixed structure is taken as an example,and the theory of the reliability is used to analyze respectively the structural resistance and the load effect after the floor slab being decorated by all sorts of materials.The floor slab's reliadility index is computed out by the limit state equation,and the maximum differential-value is lowered 1.9011 than that before decoration.Therefore,the structure safety degree is lower after renovating.
