A CALCULATION METHOD FOR THE SHEAR CAPACITY OF BRICK MASONRY WALLS STRENGTHENED WITH PRESTRESSED STEEL BELTS
-
摘要: 基于预应力钢板带加固砖砌体墙单调及低周往复水平荷载试验研究结果,采用了Ganz提出的双向受压下各向异性砖砌体墙的破坏准则对试验数据进行分析,并将理论计算结果与试验结果进行了对比分析,二者吻合较好,证明了该计算方法的可行性。此外,结合预应力钢板带加固砖砌体墙的受力特点,针对水平压应力与砖砌体墙水平抗压强度的比值给出了建议。Abstract: Based on the test results of brick masonry walls strengthened with pre-stressed steel belts under horizonal monotonic and quasi-static loading, the failure criterion of anisotropic brick masonry walls under biaxial compression proposed by Ganz was used to analyze the test data, and the results from the theoretical calculation were closer to that from the test, which proved the feasibility of the calculation method. In addition, combined with the stress characteristics of brick masonry walls strengthened with pre-stressed steel belts, some suggestions were given for the ratio of horizontal compressive stress to horizontal compressive strength of brick masonry walls.
