摘　　要：环形椭圆平面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.本文结合一长轴67m,短轴51m的环形椭圆平面弦支穹顶结构,通过有限元计算软件AN SY S对该结构环索处理和支承条件进行了分析,并对其缩比模型进行了静力试验研究,全面考察了该结构在不同的荷载工况下的静力性能,得出了一些对工程设计有意义的结论.An annular ellipse suspen-dome is a new type of structural form of suspen-domes. It integrates both benefits of a single layer reticulated shell structure and a cable-dome structure. The double ellipse suspen-dome have been analyzed by employing a model of the annular ellipse suspen-dome of 67m long axis and 51 short axis. Treatment of hoop cable and support condiction of the annular ellipse suspen-dome are analysed by Ansys programe. Experimental study on the scale model is carried out and the static behavior of the dome subject to different load cases is investigated. Some valuable conclusions are drawn for practical design.
