【摘要】 在工程设计中,随着建筑功能及造型要求的不断提高,结构形式各异的楼梯应用于工程实践中。针对某工程大跨度、大面宽的室外楼梯,采用了预应力交叉张弦钢结构的形式。结合工程实例,从结构形式、静力分析、竖向地震作用下结构响应、舒适度以及屈曲分析等方面进行了分析和设计,为今后类似的工程设计提供参考和借鉴。更多还原

【Abstract】 With architectural feature and style requirements continue to increase,more and more structural forms are used in engineering practice.A large span and large area of outdoor steel stair for a project was designed and researched,for which the prestressed cross-string structure was used.Combined with the actual project,it was made an analysis and design of the structure,from static analysis,as well as seismic response,comfort and buckling under vertical seismic load.更多还原
