This article establishes model of spatial edge joint through finite element software ANSYS,carries out a nonlinear analysis for the joints with different beam-column concrete strength grade,and evaluates the structural bearing capacity,through comparing to experimental results,it proves the effectiveness of ANSYS in the research of concrete joint.%通过有限元软件ANSYS,建立了空间边节点模型,对梁柱混凝土强度等级不同的节点进行了非线性分析,并对结构承载力进行了估算,与实验结果作比较,验证了ANSYS在混凝土节点研究中的有效性。
