摘要

板锥网壳是一种具有良好力学性能和技术经济性的新型空间钢结构。本文采用波浪叠加法对波动风荷载进行了模拟。根据板锥网壳的结构特性，通过模拟板锥网壳周围的风场变化，采用基于计算流体力学(CFD)方法的数值风洞模拟，得到了板锥网壳的结构风荷载形状因子，并与荷载规范中常用网壳的风荷载形状因子进行了比较。对板锥网壳的实际设计得到了一些重要的结论。

Numerical simulation wind analysis for plate-cone reticulated shell

Plate-cone reticulated shell is a new type of space steel structures with good mechanical behavior and technical economy. In this paper, by using the wave superposition method, the fluctuation wind loads are simulated. According to the structural behavior of plate-cone reticulated shell, the structural shape factors of wind load for plate-cone reticulated shell were gained with numerical wind tunnel simulation based on Computational Fluid Dynamic(CFD) method through simulating wind field variation around plate-cone reticulated shell, and comprised with the common reticulated shell's shape factors of wind load suggested by the Code for loads, some important conclusions for plate-cone reticulated shell are obtained for practical design.
