既有砌体砖墙检测鉴定方法及加固比对分析

Inspection&assessment and comparison of reinforcement methods of existing masonry brick walls

针对现有砌体加固工程日益增多,本文介绍了砌体结构相关设计规范及砖墙抗压强度计算方式,以便更好地掌握既有砌体结构的可靠性。同时介绍了砌体结构检测鉴定方法,通过项目案例对比分析了不同加固方式对砖墙抗压及抗剪承载力加固的效果,指出不同承重砖墙承载力加固方式的适用性及优缺点,可为既有砌体结构加固改造研究及设计提供一定的借鉴。

In view of the increasing number of existing masonry reinforcement projects,this paper systematically introduces the design specifications of masonry structure and the calculation method of brick wall compressive strength,so as to better grasp the reliability of existing masonry structures.At the same time,the method of testing and identification of masonry structure is introduced.The effects of different reinforcement methods on the compression and shear capacity of brick walls are analyzed.The applicability,advantages and disadvantages of different bearing capacity of different load-bearing brick walls can be analyzed.It provides reference for the research and design of existing masonry structure reinforcement and reconstruction.
