摘要
将桁架-拱模型理论应用于钢筋混凝土异形柱斜截面受剪承载力分析研究,以T形截面混凝土宽肢异形柱为例,提出了T形截面宽肢异形柱的斜截面受剪承载力计算公式。并与试验结果进行对比,研究表明通过桁架-拱模型理论建立混凝土异形柱斜截面受剪承载力计算公式是可行的,文中还与异形柱现行规程提出的受剪承载力计算公式进行了对比研究。该方法可为混凝土宽肢异形柱受剪承载力分析和计算提供参考。
In this paper,the theory of truss-arch model is applied to the analysis of shear loads of the inclined section of the specially shaped steel reinforced concrete column.The calculating formula of the shear load in the inclined section of T shaped column with wide flange has been brought forward.Compared with the experimental data,this formula based on the truss-arch model is proved to be suitable.In this paper,this formula is also compared with the present shear load equation of the specially shaped column.The results show that this method can be taken as a reference for the analysis and calculation of the shear load of the specially shaped column with wide flange.
