考虑一顺一丁的砌筑形式,针对纤维布加固前后砖砌体墙的特点,利用ABAQUS提供的零厚度粘结单元,建立纤维布加固砖砌体墙有限元分离模型,通过前期拟静力试验数据和相关规范公式计算结果,验证所建模型在单调荷载和往复荷载作用下的适用性。结果表明,有限元模型能有效模拟纤维布加固砖砌体墙的抗震性能,分析纤维布的加固效果,计算纤维布加固前后砖砌体墙在单调荷载作用下的受剪承载力。
Considering the one-in-one masonry form, according to the characteristics of brick masonry walls before and after the reinforcement, the finite element model of the masonry-reinforced brick masonry wall was established by using the zero-thickness bonding unit provided by ABAQUS. The test data and the related standard formula to verify the applicability of the model under monotonic load and reciprocating load. The results show that the finite element model can effectively simulate the seismic performance of brick masonry walls reinforced with fiber cloth, and analyze the reinforcement effect of fiber cloth. Calculate the shear capacity of brick masonry walls under monotonic loading before and after reinforcement.
