现场荷载法对某结构承载能力的检测分析

Detection and analysis on a structural-load-carrying capacity by using field load method

本文以某社会福利院2^(#)楼为例,采用静载模拟实际分布活荷载+无损检测的综合性现场试验方法对其结构承载力进行检测。该方法以挠度变化指标为主,承重结构材料剩余承载力为辅,综合考虑结构承载力损失、损伤变形以及结构核查情况,最后对结构剩余承载力做出评价。结果表明,该楼剩余承载能力能够保证结构安全性;该方法对于具有潜在加强作用的服役年限较强的结构具有适用性。

2^(#)Building of a Social Welfare Institute is taken as an example,which structural bearing capacity is tested by a comprehensive field test method using static load to simulate actual distributed live load&nondestructive testing.This method takes the deflection change index as its main index,and the residual bearing capacity of load-bearing structure material as its auxiliary index.All structural bearing capacity loss,damage deformation and structural verification are considered,and the residual bearing capacity of the structure is evaluated at last.The results show that the remained bearing capacity of the building can ensure the safety of the structure.Meanwhile,the method can be applied to structures which have potential reinforcing effect and long service life.
