摘要
嵌筋加固是一种新型后配筋砌体的墙体加固技术。根据高宽比为0.5和1.8的嵌筋加固墙体试验结果,对其破坏形式和破坏机理进行对比分析。结果表明,经嵌筋加固后,墙体的破坏形式不同于普通墙体。高宽比为1.8的具有斜压破坏特征;高宽比为0.5的初裂时具有剪压破坏特征,极限荷载时具有剪压和剪摩擦破坏特征。
Embedded bars reinforcing is a new post-reinforced masonry wall reinforcement technique.According to the test results of the walls aspect ratio of 0.5 and 1.8,their failure modes and failure mechanism were analyzed.The results showed that reinforced by embedded bars,the failure mode of it is different from the ordinary one.The aspect ratio of 1.8 has the characteristics of baroclinic failure;when initial cracking happens,the aspect ratio of 0.5 has the characteristics of shear compression failure;when reaching the ultimate load,it has the characteristics of shear compression failure and shear friction failure.
