摘　　要：回形刚性板式转换层能实现高层建筑上、下相邻层不同轴线及结构布置的转换．板式转换层结构设计中的主要问题是厚度的确定，而板式转换层刚度要求是决定板厚的重要因素之一．为此，结合背景工程──南京娄子巷高层公寓四期工程，对刚性板式转换层结构的刚度要求问题，展开一些理论计算和分析研究．In tall buildings, it is an easy plan to transfer upper wall substructures to lower frame-wall substructures with 回-shaped slabs. So the main problems in the design are how to determine the thickness of the transitional slab. The rigidness of transitional slabs is one of the determining factors of the thickness. So some theoretical and computational researches about the stiffiness of the model structures with 回-shaped slabs are given in the paper, linking the practical project, the tall apartment building in the area of Louzi Lane (4th stage). The results are valuable to engineers and scholars.
