高延性混凝土加固砌体墙方法研究

Study on the Method of Strengthening Masonry Wall with High Ductility Concrete

总结了采用高延性混凝土面层和条带加固砌体墙,以提高砌体房屋抗震性能的两种方法,并分析它们各自的加固要求和抗剪承载力计算公式,比较加固前后砌体墙抗剪承载力的变化。结果发现:高延性混凝土能大幅提高砌体墙的抗剪承载力,且计算公式反映的加固后墙体的承载力较试验值更偏于安全。

This paper summarizes two methods of strengthening masonry walls with high ductility concrete surface layer and stripe to improve the seismic performance of masonry buildings,and analyzes their respective reinforcement requirements and calculation formulas of shear capacity,and compares the changes of shear capacity of masonry walls before and after reinforcement.The results show that high ductility concrete can greatly improve the shear bearing capacity of masonry wall,and the bearing capacity of reinforced wall reflected by the calculation formula is more safe than the test value.
