中文摘要：
基于软化拉-压杆模型建立了内置钢构架型钢混凝土深梁的剪切力学模型和计算方法。通过对力学模型的分析,考虑混凝土软化效应,明确了型钢、混凝土、箍筋和腰筋四部分对内置钢构架型钢混凝土深梁剪切承载力的贡献,并根据建立的计算方法编制计算机程序对内置钢构架型钢混凝土深梁受剪承载力进行计算,计算结果与试验结果对比吻合良好,表明该力学模型和计算方法可以较精确预测内置钢构架型钢混凝土深梁的受剪承载力。
英文摘要：
Based on softened strut-and-tie model, shear mechanical model and calculating method of steel truss reinforced concrete （STRC） deep beam are developed. Through analyzing the mechanical model, the contributions of shape steel, concrete, stirrups and web reinforcements, to the shear strength of STRC deep beam are determined with consideration of softened effects of concrete. Then computer programs are developed to compute the shear strength of the STRC deep beams, good agreement is achieved between the theoretical predictions and the experimental results, which verified that the shear mechanical model and calculating method are accurate enough to predict the shear strength of the STRC deep beams.
