拉索预应力巨型网格结构布索形式研究
Research on Arrangement Styles of Cables for PrestressedReticulated Mega-structures
摘要
Abstract
In terms of the prestressed spatial structure system consisted of prestressed and giant reticulated shell structure,the arrangement principle of cables and struts,force mechanism,configuration and topological relations for existing two types of cable-strut arrangements were summarized.Based on the above analysis,two improved kinds of cable-strut arrangement schemes were put forward.Through the comparison of the structures with the existing two types of cable-strut arrangements and the corresponding non-pretensioned truss arch in five aspects including maximum displacement,horizontal reaction force,peak value of member internal force,ultimate load and buckling mode,the static performance and stability of the truss arches,the responses of two improved cable-strut arrangement schemes were studied.The results indicate that the structural rigidity,static performance and stability of truss arches can be effectively improved for the introduction of improved cable-strut arrangement schemes.Additionally,the defects of the existing two types can be ameliorated,which demonstrates the reasonable arrangements of the cables and struts in the two improved schemes.Comparatively,the second improved scheme had optimized comprehensive performance,and it is more efficiency.关键词
