| Abstract: | During the Northridge earthquake and Kobe earthquake, the typical beam-column moment connection in steel moment-resisting frame suffered unexpected brittle failures. By using ANSYS the nonlinear FEM four different types of connections with different details are analyzed . The conditions of stress development, the distribution of stress and the appearing orders of plastic hinges of this type steel frame under loading were analyzed. And the mechanical behaviors of the different connections are analyzed and compared. The performance on steel moment connections with reduced beam or web sections is addressed. The connection with modified detail is presented based on the results of the analysis |
