摘要
Abstract
Two kinds of new concrete-filled steel square tubular column and reduced steel beam joints with holes in flange or flange and web is presented. The non-linear finite element models considering geometric large deformation and material nonlinear are established for these joints. Comparison between analysis and experimental results is made on load-displacement curves, the stress distribution of reduced beams, the limit load capacity, the ductility, and the dissipating energy ability between analysis results and experimental results. It shows that the stiffness and ultimate load capacity of new joints are close to traditional RBS, the plastic hinge in the joints with reduced beam section can be moved to the reduced region, and the new joints display good ductility, dissipating energy ability and seismic behavior.关键词
