Analysis on Behavior of the Steel Portal Frames with End-Plate Bolted Connections

摘要

3D Integer models of steel portal frames are made to analyze the influence of end-plate bolted connections on internal force and displacement of frames by using finite element method. The results show that end-plate bolted connections are semi-rigid connections, and the flexibility of the connections affects the behavior of the frames, and their influences can not be ignored in the steel portal frames design and analysis.
