结合工程实际,对凹口型平面严重不规则超限高层的连接楼板进行了受力计算分析。本工程由于体型特点,将两栋条状建筑通过西侧宽度不大的板连接,且其连接宽度由转换层向上逐层内收,最终在20层彻底断开分为南北两个塔楼。运用ETABS程序和SATWE两种程序对凹口处连接楼板进行了罕遇地震作用下受力分析,根据分析结果及加强构造措施对连接楼板进行设计,确保了在罕遇地震作用下凹口处楼板不会断裂。
According to the engineering practice, the stress floor analysis of the connecting slab with the serious irregular upper limit of the indented plane is carried out. Due to the characteristics of the body shape of the project, the two strip-shaped buildings are connected through a plate with a small width on the west side, and the connection width thereof is inwardly and upwardly straddled by the conversion layer. In the end, the two strip buildings are completely divided into two towers. The ETABS program and SATWE program were used to analyze the stress of the connecting floor under the rare earthquakes. Based on the analysis results and strengthening the structural measures, the connecting floor was designed to ensure that the floor of the undercut at the rare earthquake Will not break.
