摘　　要： 深圳坪山体育馆屋顶采用新颖的弦支穹顶结构体系。弦支穹顶是一种刚柔杂交的预应力钢结构体系,实际工程应用较少,施工经验不足,因此针对此结构施工全过程的计算模拟分析显得十分重要。结合工程特点,充分考虑施工实际条件,选定施工方案和施工张拉顺序,对预应力张拉整体结构施工全过程进行有限元模拟计算,分析了预应力张拉过程中结构的变形、内力变化规律,确保了张拉施工过程中结构的安全。 Suspend-dome structure is adopted in Pingshan Basketball Gymnasium for Universidad 2011 Shenzhen.The suspend-dome is a prestressed structural system with the combination of rigid-flexible.Due to the less of actual projects and the lack of construction experience,the analysis of the whole construction simulation for the roof would be much important.Focused on the features of the project,considering the actual condition of the constrution,the constuction plan and the tension sequence were chosen,and the prestressed construction simulation analysis was carried out through finite element calculation.The laws of member force and deformation evolution were achieved from the analysis,which would be used to make sure the safty of the construction process.
