基于抗剪抵抗机构的无开洞RC剪力墙的极限承载力分析模型的探讨

THE INVESTIGATION ON ANALYSIS MODELS OF ULTIMATE STRENGTH OF REINFORCED CONCRETE SHEAR WALL BASED ON SHEAR RESISTANT MECHANISM

  • 摘要: 以探讨基于抗剪抵抗机构和破坏模式的带边框柱或暗柱的普通配筋形式的钢筋混凝土(RC)剪力墙极限承载力的分析模型为目的,鉴于RC剪力墙受力特性、破坏过程及破坏模式,以混凝土斜压杆为主的抗剪抵抗机构可简化成:倾角为θ的混凝土斜压杆、纵向及横向分布钢筋三部分组成。基于抗剪抵抗机构、力的平衡条件以及RC剪力墙的极限承载力的计算公式,编制了计算程序,对14片不同配筋、不同几何尺寸和受力状态的RC剪力墙进行了极限承载力分析,理论计算结果和试验结果吻合较好,可以得出该分析模型能够较好的反映无开洞RC剪力墙的极限承载力特性,可应用于不同受力状态下RC剪力墙的极限承载力验算。

     

    Abstract: The purpose of this paper is to investigate an analysis model to evaluate the ultimate strength of RC shear wall with edge-frame columns or concealed columns based on the shear resistant mechanism and failure modes. According to its mechanical behavior, failure process and modes, shear resistant mechanism of RC shear wall can be simplified as a composition of concrete inclined strut with an inclination of θ,horizontal and longitudinal bars. The calculating equations for ultimate strength are provided from shear resistant mechanism, and a program is developed to evaluate the strengths of RC shear walls. Simultaneously, the ultimate strengths of 14 RC shear walls are analyzed with this program. The analysis results agree well with those of test. It can be concluded that the analysis model verified in this paper can evaluate the ultimate strengths of RC shear walls, and the model can be used to check the ultimate strength of RC shear wall subjected to different loads.
