Study on optimization of wind load shape coefficient of typical solar greenhouse

Abstract

Solar greenhouse is an important agricultural facility in China's agricultural production. It has the functional advantages of cold proof and heat preservation, rain proof cultivation, disaster resistance, anti-seasonal regulation and so on. According to the wind sensitive characteristics of solar greenhouse, this study takes the typical solar greenhouse in Shandong as the research object, uses the CFD numerical wind tunnel method, takes the wind direction angle as the variable, carries out the simulation calculation of the surface average wind pressure of solar greenhouse, carries out the optimization research of the wind load shape coefficient, and makes a comparative analysis with the code for the design load of horticultural greenhouse structures. The practical recommended value of wind load shape coefficient is given, which provides a theoretical reference for the design, construction, production, operation and maintenance of solar greenhouse.
