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.
