摘　　要：弱连接楼盖作为协调各分肢与核心筒内力和变形的关键构件,结合某十字形弱连接的超限高层建筑,分析了弱连接区域楼板剪力得出来的几种方式;在设防地震作用下,对核心筒周边弱连接区域的楼盖进行抗剪截面及受剪承载力分析,对弱连接区域的边梁的拉应力的配筋进行复核;对罕遇地震下的弱连接楼盖进行不屈服验算。分析结果表明:弱连接区域的楼板作为传力的关键构件相对其他区域要加厚,并加强其配筋,其弱连接区域的边梁应该加强其腰筋的配筋,以满足其中震受剪弹性、大震受剪不屈服的性能目标。As the key component to coordinate the internal force and deformation of each leg and core tube,the weak-connected floor is analyzed in combination with a cross-shaped weak-connected over-limit high-rise building.Under the action of fortification earthquake,the shear section and shear bearing capacity of the floor in the weak connection area around the core tube are analyzed,and the reinforcement of the tensile stress of the side beam in the weak connection area is reviewed.Non-yield checking calculation is carried out for weak connec‐tion floor under rare earthquake.The analysis results show that the floor in the weak connection area,as the key component of force trans‐mission,should be thickened compared with other areas,and its reinforcement should be strengthened.The side beam in the weak connec‐tion area should strengthen its waist reinforcement to meet the performance objectives of moderate earthquake shear elasticity and large earth‐quake shear non-yielding.
