摘要

为了提高村镇砖墙的抗震性能，对2片双层打包带加固墙体和2片未加固对比墙进行拟静力试验，研究0.35 MPa和0.6 MPa竖向应力的作用下，墙体的破坏形态、水平承载力、滞回性能和耗能等抗震性能。试验结果表明原墙体均发生剪切破坏，加固后墙体在0.35 MPa竖向应力作用下，发生弯曲破坏，在0.6 MPa竖向应力作用下，发生剪切破坏，加固减轻墙体破坏程度，减小了裂缝宽度，破坏时加固层和墙体整体性较好；加固后墙体的开裂和极限荷载均得以提高，竖向应力大时的墙体提高幅度大；加固后墙体的滞回曲线更为饱满，试件延性和耗能能力都有提高，竖向应力较小时，加固墙体水平荷载－顶点位移骨架曲线的下降阶段更为平缓，试件延性提高了50%，耗能能力提高了447%。双层打包带加固法可明显减轻墙体的破坏，有效提高墙体抗震性能，尤其对承受较小的竖向应力时效果更好，研究成果为打包带加固方法的发展和村镇砖墙实地加固提供参考。

Abstract

In order to improve the seismic performance of rural brick walls， pseudo-static tests on two brick walls strengthened by two double-layer packing belts and two unreinforced brick walls was performed. Seismic performance such as the failure mode， horizontal bearing capacity， hysteretic performance， and energy dissipation was studied under the vertical stress of 0.35 MPa and 0.6 MPa. The test results show that the two original walls were in shear failure， and the reinforced wall was in bending failure under the vertical stress of 0.35 MPa and was in shear failure under the vertical stress of 0.6 MPa. The reinforcement reduced the damage degree and the crack width of the wall， and the reinforcement layer and integrity of the wall were good when the wall was damaged. The cracking and ultimate load of the wall increased after reinforcement， and increased greatly when the vertical stress was large. After reinforcement， the hysteretic curve of the wall was more full， and the ductility and energy dissipation capacity of the specimens was improved. When the vertical stress was small， the descending stage of the horizontal load-peak displacement skeleton curve of the strengthened wall was more gentle， and the ductility of the specimens was increased by 50% and the energy dissipation capacity was increased by 447%. The double-layer packing belt reinforcement method can significantly reduce the wall damage， and effectively improve the wall seismic performance， especially when in a small vertical stress. The research results can provide reference for the development of rural brick walls reinforcement and in practical engineering.
