摘要

针对传统模型无法考虑轴压比影响和需要引入经验位移延性修正系数所存在的缺陷,研究建立了剪切破坏型钢筋混凝土(RC)柱的改进抗剪承载力分析模型。首先结合变角桁架-拱模型的变形协调条件和考虑轴压力影响的临界斜裂缝倾角模型,建立了能够综合考虑轴压比影响和桁架-拱模型变形协调条件的改进抗剪承载力分析模型,然后分析了轴压比对剪切破坏型RC柱抗剪承载力的影响机理,从而有效克服了传统模型无法考虑轴压比影响和需要引入经验位移延性修正系数所存在的缺陷,最后通过与试验数据和国内外现有模型的对比分析,验证了该模型的有效性和适用性。

Abstract

In order to overcome the disadvantages of traditional modes which cannot take into account the influence of axial load ratio and need to introduce empirical corrected factor of displacement ductility, an improved shear strength model for shearcritical reinforced concrete (RC) column was proposed. Firstly, an improved shear strength model for RC columns which takes into consideration the influences of axial load ratio as well as the deformation compatibility condition of variable angle truss-arch model was established based on the critical crack angle model that takes into account influence of axial load ratio as well as the deformation compatibility condition of the variable angle truss-arch model. Then the influence of axial load ratio on the shear strength of shearcritical RC columns was discussed. The proposed model overcomes the disadvantages of traditional models. Finally, the applicability and accuracy of the proposed model were validated by comparing with the experimental data and existed models.
