摘　　要：基于ACI规范压-拉杆模型设计方法,建立了型钢混凝土(SRC)深梁的压-拉杆模型。根据收集到的25个深梁试验数据,分别采用我国规范关于SRC深梁的承载力计算方法和本文提出的压-拉杆模型,对其承载力和破坏模式进行预测,并与试验结果进行对比。结果表明,我国规范关于SRC深梁的承载力计算结果误差较大,论文提出的压-拉杆模型能较好地计算SRC深梁的承载力。Based on the Strut-and-tie models of ACI code,the strut-and-tie model of steel reinforced concrete deep beam was set up.The strut-and-tie model proposed in this paper and the capacity calculation method in the current Chinese code were compared based on the test data,to estimate the bearing capacity and failure mode,including 25 specimens of deep beam.The resurt shows that the strut-and-tie model method gives better prediction for SRC deep beams than that of the current Chinese code method.
