| 摘 要： | 运用通用有限元分析软件ANSYS,对变梁异型节点在梁端施加正反对称荷载作用时,节点区内混凝土的裂缝发展和破坏形态进行分析,由分析结果可以看出,节点区内裂缝发展都经历初裂、通裂、极限和破坏四个阶段,且随着梁高差的不断加大,变梁异型节点以小核芯区剪切破坏为主。

| Abstract: | In this paper,using the finite element analysis software ANSYS,the abnormal frame joint exerted positive and negative symmetrical load at the end of the beam,crack development and failure form of node area concrete analysis,the node area crack development have first crack, crack,limit and destruction in four stages,and with the beam height continuous increase,abnormal frame joint shear failure mode in the small core area. |
