【摘要】 双椭型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。为进一步研究不同布索方式对双椭型弦支穹顶结构静力性能的影响,对一长轴6.7m,短轴5.1m的双椭型弦支穹顶结构,对影响该结构静力性能的两种布索方式进行了分析,结合试验数据,得出了布两圈索杆时,结构的最大竖向位移、最大环向杆轴力均得到较好的改善,下部索杆体系满布,并不能最好地改善结构的受力性能。更多还原

【Abstract】 A double ellipse suspenddome is a new type of suspend-dome structural form.It integrates both benefits of a single layer reticulated shell structure and a cable-dome structure.To research the effect of different cable arrangements to the double ellipse suspend-dome,two cable arrangements of the double ellipse suspend-dome,which influence the structural static capability,have been analyzed by employing a computational model of the double ellipse suspend-dome of 6.7m long axis and 5.1 short axis.Combining the results of the experiment,some valuable conclusions are drawn for practical design,when two cable arrangements of the double ellipse suspend-dome is carried out,the maximum vertical displacement and the force of round pole are made preferably.更多还原
