摘　　要：为解决传统装配式浅圆仓仓顶结构模具成本高、存储运输不便等问题,提出了一种装配式浅圆仓折板仓顶结构。采用分层壳单元数值模拟方法,深入研究该结构在竖向均布荷载下的结构变形与板缝传力性能。与现有单曲率仓顶结构进行对比,分析不同倾角对折板仓顶结构受力性能的影响,确定倾角为25°时结构的承载性能最优。研究结果表明,装配式浅圆仓折板仓顶结构满足承载力规范要求,板缝连接设计有效实现了内力传递,展现出良好的受力性能。此外,该结构还具有建造效率高、成本低等优势,为装配式浅圆仓的设计与应用提供了新思路,具有广泛的推广前景。To address the issues of high die cost and inconvenient storage and transportation of traditional prefabricated shallow round silo roof structure,a prefabricated folded plate shallow round silo roof structure is proposed.By using the numerical simulation method of layered shell units,the mechanical performance of this structure under vertically distributed loads is thoroughly studied,including structural deformation and force transmission performance between plate joints.By comparing with the structural tests of existing single curvature silo roof structures,the influence of different inclinations on the force performance of the folded plate roof structure is analyzed,and 25° is determined as the optimal inclination angle,at which the structural bearing performance is optimal.The research results show that the prefabricated folded plate silo roof structure not only meets the requirements of load-bearing specifications,but also effectively achieves force transmission through the plate joint design,demonstrating good force performance.In addition,this structure also has advantages such as high construction efficiency and low cost,providing new ideas for the design and application of prefabricated shallow round silos,with broad prospects for promotion.
