| Abstract: | The representative 3D FEA-model of haunched node of steel moment-resisting frame is set up and it is analyzed nonlinearly.The characteristic of stress distribution in connection is expounded and the stress distribution rules in haunched node and ordinary node are compared.Then the stress distribution is analysed along the definite path to judge the influence on the post-haunched node by using the displayed function of Ansys tridimensional section. |
