一种新型预应力空间结构——劲性支撑穹顶
|
摘要
基于索穹顶结构的技术难点以及高强钢拉杆性能特点,介绍了劲性支撑穹顶结构的构造.劲性支撑穹顶结构是由上部的预应力空间索网与下部的刚性支撑杆系组成的一种新型预应力空间结构.通过对不同跨度下索穹顶结构的拉索截面和劲性支撑穹顶结构刚性杆截面以及劲性支撑穹顶结构内部拉索与刚性杆截面对比分析,确定了劲性支撑穹顶结构的拓扑形式,验证了劲性支撑穹顶结构的合理性,并探讨了劲性支撑穹顶结构的发展前景与面临的主要技术问题.
On the analysis of the technical difficulties of cable domes and the latest research progress at high-strength rigid rod,rigid bracing dome was introduced in the paper.Rigid bracing dome is a new type of prestressed space structure.The upper part of structure is composed by prestressed cable net and the lower part is composed by rigid support system.Two sets of data were compared and analyzed.One is the rod cross-sectional areas of rigid bracing dome and the cable cross-sectional areas of cable dome in different span.The other is the cable cross-sectional areas and the rigid rod cross-sectional areas of rigid bracing dome.On the basis of the above analysis,the topology of rigid bracing dome was proposed,and the rationality of rigid bracing dome was testified.Finally,prospect and some major technical problems of rigid bracing dome were studied.
