摘要
Abstract
In order to study the seismic resistance of intersection joints of vierendeel sandwich plate with column in steel-grid structure,five composite side column joints were conducted. The experimental phenomenon,failure process,load bearing capacity,hysteric curve,ductility and energy dissipation were investigated and analyzed. Results show that,the composite joint and bare steel joint of vierendeel sandwich plate with column in steel-grid structure have good seismic resistance. Compared with the strong axis joints,the loading bearing capacity,stiffness and energy dissipation of the weak axis joints have a certain degree of weakening. But it still has a good seismic performance. The stiffener between the upper and lower T-shaped beams played a role of improving the seismic performance of the joints,especially on the weak axis node. The seismic performance of the joints improves obviously because the upper and lower T-shaped beams are directly welded on the column web plate which make the upper and lower T-shaped beams can work together better. What is more,the width increase of stiffening rib can control the stress concentration and the purpose of the plastic hinge location.关键词
