( East China Architectural Design & Research Institute Co., Ltd., Shanghai 200002, China)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.
Keywords: high-rise building beyond the scope of design codes; tlun-link slab; computation and analysis; design of slab
