摘　　要：楼梯不仅是关系建筑功能、安全疏散等的重要结构构件,在许多现代建筑中也成为建筑师营造特殊建筑效果的重要元素。介绍了一种类似风琴折的连续折板∏形悬挑楼梯的设计计算。采用有限元软件建立该楼梯的实体模型,对其进行计算分析,根据分析结果进行了该楼梯设计配筋及舒适度验算,并给出了此类楼梯的一些构造建议。Stairs not only relate to the function and security of buildings,but also are the important elements of special architectural effect created by architects in many modern buildings.A design method was introduced on the continuous folded plate cantilever stair with ∏ shape.The finite element method was adopted to create the model and analyze the stress and deformation of the stair.Based on the analytical results,the reinforcement and the comfort degree of the stair were designed,and some suggestions of the structure were given.

关 键 词：悬挑楼梯 踏步 舒适度验算 设计配筋
