摘要
由于建筑立面造型的需要,结构在上部楼层需要实现竖向整体内收,基础顶~5层、8~12层、18~22层和28~32层采用斜柱,采用YJK软件对比分析斜柱方案和转换方案对结构整体指标的影响,同时分析斜柱对结构梁板和核心筒的影响。结果表明,斜柱能够增加结构的整体刚度,同时对梁板产生拉力,应对斜柱起始处梁采取增设型钢和板加大配筋等措施保证水平力的传递,并应加强节点构造,使节点构造满足节点后于构件破坏。
Due to the need of building facade modeling, the structure needs to achieve vertical overall adduction on the upper floor. Inclined columns were used for the foundation top^5 floors, 8 ~12 floors and 28~32 floors. The influence of inclined column scheme and conversion scheme on the overall index of the structure was compared and analyzed by YJK. The analysis results show that the inclined column can increase the overall stiffness of the structure and at the same time produce tension on the beam and plate. Measures such as enhancing the beam with profile steel and using more reinforcement in the slab that located at the beginning of the inclined column should be taken to ensure the transmission of horizontal force,and the node should be strengthened to make the node meet the requirements of the node failure after the component failure.
