摘要
结合某三层砌体结构房屋,分析了抗震构造措施和抗震承载力不满足规范要求,部分承重墙的现状质量较差,且已经出现了不同程度损伤的现状。结合该房屋的特点提出对应的加固改造设计方案。选择采用高延性混凝土(HDC)面层加固砌体墙。通过PKPM软件进行建模试算,选择一个经济的HDC面层加固厚度。对HDC面层加固前后的计算结果进行对比分析,得出:经过HDC面层加固后,砌体墙的受压承载力增大了2倍~3倍,房屋的楼层综合抗震能力指数增大了1倍~2倍;构造上通过设置组合构造柱、勾缝等相关措施加强房屋的整体性;经过加固后房屋满足继续使用的要求。
Based on a three-story masonry structure house with wood-based floor slabs,this paper analyzes the current status where the seismic detailing measures and seismic bearing capacity fail to meet the code requirements,and some loadbearing walls are of poor quality with varying degrees of damage,corresponding strengthening and rehabilitating design schemes are proposed based on the characteristics of the building.The High Ductility Concrete(HDC)surface layer is selected to reinforce the masonry wall.Using PKPM software for modeling and calculation,select an economical thickness of high ductility concrete layer.Comparative analysis of the calculation results before and after HDC layer reinforcement shows that after HDC layer reinforcement,the compressive bearing capacity of the masonry wall increases by 2~3 times and the comprehensive seismic resistance index of the building floor increases by 1~2 times;The measures of construction such as setting up composite columns and filling jointing with cement mortar are taken to enhance the integration of the structural;After reinforcement,the house meets the requirements for continued use.
