为了研究不同加固方式、加固不同损伤程度墙体的抗震性能,通过对玄武岩纤维布(BFRP)加固后的4片墙体进行低周反复荷载试验,并分析其破坏形态、承载力、变形性能、耗能能力、加固效果等.研究结果表明:采用BFRP加固砌体墙的方法,可以不同程度的提升墙体的极限承载力及延性,提高墙体的整体性,延缓刚度退化,从而改善墙体抗震性能.
In order to study the seismic performance of different reinforced walls with different degree of damage, low-cycle repeated loading tests were carried out on four walls strengthened with basalt fiber cloth (BFRP), and their failure modes, bearing capacity and deformation performance were analyzed. Energy dissipation, reinforcement effect, etc. The results show that using BFRP to reinforce masonry walls can improve the ultimate bearing capacity and ductility of the wall to some extent, improve the integrality of the walls, retard the stiffness degradation and thus improve the wall Seismic performance.
