Experimental Study on Hysteretic Performance of Steel Frame with Improved Node

Abstract:

Using the test and finite element analysis methods study the load-displacement hysteretic performance of the widened beam flange connections steel frame under the low cyclic load. Results of the research show that under the low cyclic load, the plastic hinge of steel frame with widen beam flange connections can be moved out of the beam-column connection welding. And the centers of plastic hinge locate out of widened arc part, achieving the ductile design goals that avoid the brittle break near the welding seam at the end of the beam. The bearing capacity of the steel frame with widen beam flange connections has been improved, but the stiffness of the column web domain is relatively lower. So construction measures should be taken to reinforcing the column web domain.
