摘要
预应力桁架壳体系是在张弦结构基础上发展起来的一种新型空间杂交张拉结构。详细介绍了大跨度预应力桁架壳体在2008年奥运会乒乓球馆——北京大学体育馆复杂造型屋面中的具体应用。包括不规则曲面屋面的形态设计,屋盖结构体系的布置特点,荷载取值,初始态张拉分析,静力性态分析,动力分析,非线性屈曲分析以及拉索锚固节点弹塑性分析等。分析方法和结果可供类似结构的分析、设计参考。
The pre-stressed truss shell system is a new-style spatial hybrid tension structure developed on the basis of beam string structure.The application of large-span pre-stressed truss shell system is introduced in complex form roof of Table Tennis Gymnasium for the 2008 Olympic Games——Beijing university gyms in detail,including roof form design of irregular curved surface,the characteristic of the roof structure system,loads calculation,initial tension analysis,static performance analysis,dynamic analysis and nonlinear buckling analysis.Finally,elasto-plastic analysis has been performed for the anchor joint of the cable on the bottom chord of the trusses.The analysis procedures and results might be used as reference for the analysis and design of this kind of structures.
