【摘要】 水泥砂浆加固砌体墙是加固砌体结构的常用方法,现阶段人们对该加固方法的关注点集中在加固前后墙体抗震性能的改变方面,对于不同破坏类型对骨架曲线的影响关注较少。本文以15片低强度砖墙经单面水泥砂浆加固后的抗测力试验为例,介绍了试验的基本情况以及在不同竖向压应力情况下墙体的破坏类型,总结了墙体的骨架曲线,提出了适用于墙体不同破坏类型产生的骨架曲线的建议公式。以期为该加固方法的工程应用及相关规程的修订提供参考。更多还原

【Abstract】 Cement mortar reinforced masonry wall reinforcement method is commonly used in masonry structure,the focus of the reinforcement method is on the seismic performance of the wall before and after the reinforcement at present,the effect of different damage types on the skeleton curve is less. In this paper,an example is given for the resistance test of 15 low-strength brick walls reinforced with single-sided cement mortar,the basic situation of the experiment and the damage type of the wall under different vertical compress stress are introduced,the skeleton curves of the wall are summarized,the proposed formula of skeleton curve for different damage types of wall is suggested to provide reference for the engineering application of the reinforcement method and the revision of relevant regulations.更多还原
