摘要:
针对索穹顶结构形式单一和上弦脊索易退出等欠缺，提出一种正方形刚性索穹顶结构，该结构与张弦梁相比，在跨中净高上具有优势．以一个跨度为48 m，矢跨比为1/16的正方形刚性索穹顶结构为例进行性能研究，采用基于正交设计响应面的Monte Carlo法，对其进行双随机下的可靠性灵敏度分析，并与相同跨度和矢跨比的张弦梁结构比较．结果表明，在相同荷载作用下，正方形刚性索穹顶结构的最大位移要小于张弦梁结构；在位移控制下，刚性杆件截面积和荷载对正方形刚性索穹顶结构失效较为敏感；刚性杆件截面积、荷载和外圈斜索的预应力水平对张弦梁结构失效较为敏感．
Abstract:
To solve the withdrawal problem of ridge cables and the singleness of the form in cable dome structures of cable dome structure, a new square rigid cable dome structure is presented, and the clearance of the new structure is higher than that of the beam string. A 48 m-span and 1/16 rise-span ratio square rigid cable dome is studied. The Monte Carlo method based on orthogonal design response surface is employed to analyze the reliability sensitivity under double randomness. Compared with a beam string of the same span and rise-span ratio, the results show that the maximum displacement of the square rigid cable dome is smaller than that of the beam string. Controlled by displacement, the random variables including sectional area of rigid member and load are more sensitive for square rigid cable dome structural failure while sectional area of rigid member, load and prestress level of outermost diagonal cable are more sensitive for beam string
