Abstract: In the context of the full implementation of the action plan for the seed industry revitalization proposed in the No. 1 Central Document in 2022，the role of crop variety testing is increasingly critical. As an agricultural facility building widely used in the drought resistance test of varieties, there is no mature design scheme at present, and the theoretical guidance of design is urgently needed. This paper summarizes the basic types and structural systems of current domestic movable rain shed. Taking the design of 12meterspan movable rain shed in Zhanjiang City of Guangdong Province as an analysis case, combing the provisions and instructions of relevant specifications and the design period is proposed to be 20 years, the design base period is 30 years, the safety level of the building structure is three, the structural importance coefficient is 0.90. The structural model is established for analysis and calculation, the reasonable size of the components is selected, the corresponding steel consumption is counted, and the precautions and corresponding solutions in the design are put forward, which can provide reference for the design of the movable rainproof shed in the future.

Key words: movable rain shed, drought resistance test, stress analysis, windresistant measure
