对高层大跨度连体结构的连体部分进行了结构选型分析,比较了空腹式、上承式、下承式和斜拉式等四种桁架布置形式的连体竖向刚度和结构竖向规则性,研究了上述四种连体结构布置形式下的构件内力分布和楼板应力,分析结果表明斜拉式桁架具备较好的竖向刚度,结构竖向规则性较优,且构件内力和楼板应力分布较为均匀.对高层连体结构的竖向地震作用进行了研究,结果表明大跨度连接体的竖向地震响应较大,在高烈度场地必须重视其对连体受力影响.
Siamese structure of the high-rise long-span Siamese structure part selection analysis, compared the fast-type, the last type, the next type and the type of truss truss arrangement of the form of vertical stiffness and structural vertical Regularity, the internal force distribution and the floor stress under the four kinds of conjoined structures are studied. The analysis results show that the inclined truss has better vertical rigidity, the vertical regularity of the structure is better, and the internal forces of the members and the floor The stress distribution is more uniform.The vertical seismic action of high-rise Siamese structure is studied.The results show that the vertical seismic response of long-span connection body is large, and the impact on the Siamese body stress must be emphasized in the high-intensity site.
