摘要:
针对既有空斗墙砌体结构未设置圈梁、构造柱的问题,提出采用HPFL条带加固形成组合圈梁构造柱的方法,制作了6片HPFL条带组合圈梁构造柱的空斗墙和6片对比墙体,进行水平往复荷载试验,比较各墙体的破坏形态、承载力、耗能能力、刚度退化等抗震性能指标。试验结果表明:HPFL条带组合圈梁构造柱能大幅提高空斗墙的抗震抗剪承载力,改善墙体的延性和耗能性能。基于试验结果,建立有限元分析模型,计算研究构造柱尺寸、圈梁尺寸、构造柱间距和开洞墙体构造柱设置方式等因素对空斗墙抗剪承载力的影响,提出了HPFL条带组合圈梁构造柱的设计建议。
Abstract:
Aiming at not considering the seismic fortification of the cavity masonry structures, a method of cavity walls with HPFL strips composite ring beam and constructional column is proposed. Six cavity walls with HPFL strips composite ring beam and constructional column and six comparative walls are tested under low cycle reversed loading to study the effect of the strengthening method.Comparison of the failure pattern, ultimate strength,skeleton curve and stiffness degradation of the strengthened and the comparative walls shows the beneficial effects of the composite ring beam and constructional column.The test results show that seismic capability, ductility and energy dissipating capability of the cavity walls with HPFL strips composite ring beam and constructional column are increased greatly. Based on finite element calculation, the various influence factors are analyzed, such as HPFL strips composite constructional column dimension, composite ring beam dimension, composite constructional column spacing and constructional column setting of cavity walls. Some specific design suggestions on HPFL strips composite ring beam and constructional column are proposed.
