已有建筑物可靠性的权函数评定法

Rating Method by Weight Function for the Degree of Reliability of Existing Buildings

基于已有建筑物安全性的鉴定方法,依据现行规范近似概率极限状态设计法,以建筑物结构各构件失效影响参数作为构件的权函数,分析了建筑物整体可靠系数,以此对建筑物结构进行整体安全评定,提出了权函数可靠度评定法,并进行了工程实例验证.

Based on the identification method about the of security existing buildings, according to the approximate Probability-based limit state design method of the current codes, the failure＇s influential parameter was regarded as weight function of the structure member of the building, the whole reliability parameter applied to the buildings reliable rated has been analyzed. The rating method has been advanced by weight function. It has been applied to a practical engineering example.
