摘要
该文针对天津现存的历史风貌建筑普遍存在砂浆强度低的情况,进行了墙体结构加固试验与模拟计算分析。采用原材料制作了2片墙体试件、2片钢筋网水泥砂浆抹面加固试件,对其进行了低周反复加载试验,研究了砖砌体及加固砖砌体试件的抗震性能;应用等效体积单元(RVE)法模拟砖砌体,求得了砖砌体的等效参数,用ANSYS模拟了加固砖砌体试件的低周反复加载,并与试验结果进行了对比分析,验证了钢筋网水泥抹面加固低强度砖砌体的可行性,为历史风貌建筑的加固提供技术支撑。
The reinforcement experiment and simulation analysis of a wall structure have been carried on in this paper, in view of low-strength mortar in the extant historical character buildings in Tianjin. 2 test pieces of brick masonry wall and 2 reinforced pieces with steel-meshed cement mortar layers were manufactured with original material to carry on a low frequency cyclic loading test and study the seismic performance. The representative volume element （RVE） method was applied to brick masonry, obtaining its equivalent parameters. Low frequency cyclic loading test of the reinforced brick masonry pieces was simulated with ANSYS, and a comparative analysis with the test results has been carried on, confirming the practicability of the reinforcement method mentioned by this paper and offering technical support for the reinforcement of historical character buildings.
