| Abstract: | The fine finite element model was set up for top and seat angle with double web angles steel beam-column connection and the nonlinear finite element calculation on the model was carried out,then the bearing capacity,ultimate deformation status,failure mechanism and deformetion status of top and seat angle with deuble web angles steel beam-column connection under monotonic loading were analyzed.The pre-tightening force of high-strength bolts connecting with the top and seat angle with double web angles steel beam-column was deeply discussed as well as the mechanical behavior of contact pressures between angle steel and beam-column.In this way,the mechanical properties were obtain,which was difficult to achieve by stets and provided a theoretical basis for the top and seat angle with double web angles steel beam-column connection applying in projects. |
