【摘要】 以山东滨州会展中心钢屋盖结构为工程背景,详细地分析了H型钢组成的肋环形和扁五角锥单层折板网壳结构的受力特性,同时根据变形及内力的分布,介绍了杆件、连接节点和支座节点的设计。指出在大跨度屋盖结构中,H型钢截面杆件的连接可以采用传统的钢结构连接方式,同时肋环形折板结构体系的推力自抗性能使下部结构的负担较小。更多还原

【Abstract】 As Shandong Binzhou Conference and Exhibition Center for the engineering background,the force-bearing properties of meridional folded plate latticed shell are analyzed with the shape of flat five-pyramids consisting of the H-shaped steel members.Based on the distribution of deformation and internal force,the design of members,connections and bearings are introduced.It is pointed out that the traditional connection types of H-shaped steel members can be adopted in the large span roof structures,and the performance of thrust self-resistance in the structural system makes the structural design easy.更多还原
