各种装修材料对楼板可靠度的影响研究

Influential researches of renovation on structural reliability of floor materials

在建筑物楼板装修中使用的各种装饰材料如硬木、瓷砖和石材等,将增加楼面恒荷载并影响到结构的安全性。以某多层砖混结构楼板装修为例,楼板用各种材料装修后,由可靠度理论对结构的抗力及荷载效应分别进行了分析,通过极限状态方程计算出楼板装修前后可靠指标最大差值为βmax=1 9011。因此,楼板装修后,结构的安全性降低。

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.
