对吴淞口国际邮轮码头椭球面屋盖结构的初步设计成果进行了简单介绍.该屋盖结构采用肋环型(局部抽杆)单层网壳结构体系,在网壳周边开孔处设置截面高度为1.5m的箱形截面拱梁.体系为比较少见的长向传力结构,结构方案设计具有难度.经与建筑师深入沟通,添加内部8个树状支座后,体系力学性能得到大幅度提高,从而节省了造价.本文给出该方案的设计分析结果,体系静动力性能、稳定性均满足规范要求.
The preliminary design results of roof structure of Wusongkou international cruise terminal ellipsoid are briefly introduced.The structure of the roof structure is single-layer reticulated shell with rib ring type (partial pumping rod), and the cross-section height 1.5m box-shaped cross-section arched beam.The system is a relatively rare longitudinal force transmission structure, the structural scheme design is difficult.After in-depth communication with the architect, adding the internal eight tree-shaped bearings, the mechanical properties of the system are significantly So as to save the cost.In this paper, the design and analysis results of the scheme are given, and the system’s static and dynamic performance and stability meet the requirements of the standard.
