砌筑砂浆强度等级降低后的砌体结构安全性探讨

On Masonry Structure Safety of Mortar Strength Downgrading

以《建筑结构荷载规范》、《砌体结构设计规范》和《建筑结构可靠度设计统一标准》为依据,讨论了砌体结构砌筑砂浆强度降低对砌体结构安全性的影响,得出结论:一般情况下当砂浆强度降低一个等级后,砌体承载力能满足使用荷载要求,但由于砌体结构可靠度降低,故砌体结构存在一定的安全隐患。

According to Load Code for the Design of Building Structures, Code for Design of Masonry Structures and Unified Standard for Reliability Design of Building Structures, this paper discusses the influence of mortar strength downgrading to masonry structure safety. Then we can draw a conclusion as follows. Generally,load capacity of masonry structure could meet regular service, alter mortar strength is reduced by a grade. But potential hazard still exists in masonry structure because of the reduction of reliability for masonry structure.
