摘　　要：对高层建筑钢结构中采用的双腹板、顶底角钢半刚性连接进行了静力加载实验研究;针对不同尺寸的构件,研究了顶底角钢、腹板角钢、梁翼缘和腹板在荷载作用下的应力情况,确定了该种连接在静力荷载作用下的受力性能及破坏模式,得到了其M—θ曲线、极限承载能力Mu、极限转角、初始刚度Kl,初步分析了影响该种连接静力性能的因素以及影响程度。The static behavior of the top and seat angles with double web angles being connected semirigidly in the tall building of steel structure is studied. Different dimensional members are loaded statically,and the stresses on the top and seat angles,web angles,beam flange and web are analyzed respectively. The static behavior and failure mode of the semirigid connection are determined,and the Mθ relation,the ultimate bearing capacity,the ultimate angle of rotation and the initial stiffness are obtained. The factors which influence the static behavior of the connection and the rate of contribution are analyzed.
