考虑混凝土板组合效应的蜂窝钢梁柱连接抗震性能试验研究
Experimental study on seismic performance of cellular beam column connections considering composite action of floor slab
摘要
Abstract
In order to investigate the effect of composite action of floor slab on the seismic performance of cellular beam column connections,the hexagon-hole cellular beam column connections with and without composite floor slab and the solid web composite beam column connection were tested under cyclic loading to study the effect of composite action of floor slab on the failure modes,bearing capacity,rigidity,ductility and energy dissipation capacity of composite cellular beam column connections with different opening ratios.The experimental results indicate that the plastic hinge of cellular beam column connections are generated at the first cellular hole near the column,the plastic hinge is moved away from the column to reduce the possibility of brittle failure at the beam column connection weld.The composite action of floor slab can reduce the effect of shear deformation,and the hysteretic curves of cellular beam column connections with composite floor slab are fuller than those without composite floor slab.The composite action of floor slab can improve the bearing capacity,ductility,stiffness and energy dissipation capacity of cellular beam column connections.With the increase of the opening ratio,the combination effect is more significant,but the composite action of floor slab reduces the rotational capacity of plastic hinge regions.关键词
