采用非线性有限元法分析了梁柱节点的受力性能。该模型使用第三作者的测试结果进行了校准。梁柱外节点的受力性能不同于内节点。影响抗剪强度的参数对于两种类型的连接是不相同的。对影响梁柱外节点抗剪承载力的主要参数，如节点长径比、柱配筋率、混凝土抗压强度、梁筋锚固效率、抗剪钢筋的数量和效率等进行了研究。对于梁柱中节点，影响节点抗剪承载力的主要因素是混凝土抗压强度。还与建议的抗剪强度方程进行了比较。
A nonlinear finite element analysis is used to investigate the behavior of exterior and interior beam-column joints. The model was calibrated using results of the third author's tests. The behavior of exterior beam-column joints turned out to be different from that of interior connections. The parameters influencing the shear strength are not the same for both types of connections. The main parameters influencing the shear strength of exterior beam-column connections such as joint slenderness, the column reinforcement ratio, concrete compressive strength, efficiency of the beam reinforcement anchorage, and the amount and the efficiency of the shear reinforcement are investigated. For interior beam-column joints, the main factor affecting the shear strength turned out to be concrete compressive strength. A comparison is also done with proposed shear strength equations.
