摘　　要：小跨高比连梁的受剪承载力计算公式源于试验结果,但试验数据较少,缺乏合理的理论计算模型。本文利用软化拉压杆模型理论计算小跨高比连梁的受剪承载力,结果表明软化拉压杆理论能够较准确地预测小跨高比连梁的受剪承载力。The formula of shear bearing capacity of deep coupling beams originates from test results, however the test data are few and the calculating model isn＇t very rational. The shear bearing capacity is calculated by softening strut-and-tie model method in this study. Compared with experimental results, the calculated values of shear strength are almost equal to the experimental values.
