| Abstract: | The hysteretic behavior of top-seat-angle steel beam-column connections under cyclic loading is presented and full-scale model of top-seat-angle steel connections is analyzed by using ANSYS.The failure mechanism and ultimate deformation of top-seat-angle steel beam-column connections are analyzed.Then the preload of bolt,the contact pressure of components and the mechanical properties between other components of the connections are studied.These results can provide good reference for the engineering design. |
