摘要
针对现有砌体结构墙肢宽度超限,研究短肢砌体墙在板墙加固前后的工作性能、受剪承载力及破坏形态。本文采用了两片高宽比为1.75的砖墙,进行了全尺寸模型的水平低周反复荷载试验。试验研究表明,未加固短肢砌体墙片发生弯曲受压破坏,板墙加固的短肢砌体墙片发生弯曲受拉破坏。结合试验现象给出了板墙加固短肢墙体发生弯曲受拉破坏时的抗剪承载力计算公式,计算与试验结果基本吻合,可供工程设计及加固时参考。
For the overrun existing masonry shear wall width, two pieces full size brick wall models with ratio of height to width aspect 1.75 are studied in the pseudo-static test in order to research the seismic performance and shear capacity and failure form of short-leg masonry shear wall reinforced with concrete splint. Experiment shows that unreinforced short leg masonry shear wall is in bending compression damage, concrete slab reinforced short leg masonry shear wall is in bending tensile damage. One formula for short-leg masonry wall reinforced with concrete splint failing of bending tensile model shear capability calculating is proposed which agrees well with the experimental results,and can be a reference for engineering design and reinforcement.
