ABSTRACT=This paper studies the wind load acting on the point focus solar furnace that is composed of 110 m2 heliostat and 77 m2 concentrator through wind tunnel test. Based on the wind tunnel test data under 305 different working conditions, the variation law of the wind pressure coefficient, power spectral density, and wind load coefficient of the heliostat and the concentrator are analyzed. The results show that due to interaction between the concentrator and the heliostat, the wind speed near the heliostat and concentrator decreases but the turbulence intensity increases, which causes the peak wind load coefficient to rise slightly. It is suggested that the safety factor of 1.1 to 1.2 should be considered for structural design and optimization of the solar furnace.
