| 摘 要： | 拟建于上海的某超高层建筑,立面造型为梭形,结构体系采用了筒中筒结构,根据其特殊的建筑造型,外筒采取了斜柱方案。分析表明,翼框柱的倾斜可以改变结构的侧向刚度和楼层内力的分布,内筒和外筒的腹板框架承担了更大的层内力;结构上部的刚度增加,下部的刚度减小。建议在结构底部适当提高核心筒混凝土墙中钢骨的含骨率,并且把外筒钢柱改成型钢混凝土柱,以提高结构的刚度、承载力和延性。

| Abstract: | A super-high rise building with shuttle-shaped profiles,which will be constructed in Shanghai,is a tube-in-tube structure.Most of the columns of the outer tube are leaning due to its special architecture shape.The influence of leaning columns on the inner force and rigidity of the framed tubes is presented,and the mechanic behaviors of the tube-in-tube structure are analyzed in detail.The conclusions provide a reference to similar projects for structural designers. |
