[摘要] 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。

Abstract: Combined with a practice engineering project, the tlun-link slab on a high-rise building beyond the scope of desing codes were analysised. According with the shape of the structure, two strip shape buildings were connected by the thin-link slab. The width of the slab were changed layer by layer, ultimately, the tower was completely disconnect on twentieth story and was divided into north tower and south tower. Thin-link slab were analyzed under severe earthquake by ETABS and SATWE, The slab was designed based on the results of the analysis to ensure that thin-link slab of every floor was safe under severe earthquake.
