摘　　要：双椭形弦支穹顶是弦支穹顶结构的一种新型结构形式,它综合了单层网壳结构和索穹顶结构的优点。通过对一长轴6.7m,短轴5.1m的双椭形弦支穹顶进行模型试验,用有限元计算软件ANSYS对结构成型过程进行了全过程跟踪计算,重点分析了张拉过程中,结构变形、结构内力变化规律,从而验证张拉成型理论方法的正确性、可行性。Being a new type of suspen-dome structure, double ellipse suspen-dome integrates the advantages of both single layer reticulated shell structure and cable-dome structure. The test was carried out with a computational model of double ellipse suspen-dome of 6.7m major axis and 5.1m minor axis. And the construction process tracing computation was conducted by ANSYS FEM software with emphasis on analyzing the law of structure distortion and internal force in tension-shaping process while the validity and feasibility of the construction method were proved by theory and test at the same time.
