摘　　要：设计人员在设计钢筋混凝土大仓特大仓甚至巨仓时，温度应力成为难题。本文主要研究了大直径钢筋混凝土筒仓所受的日照温差、季节温差和内外温差引起的温度应力，并给出了在设计中应考虑的大小及计算方法。In the design of the large and huge R. C silo,the temperature action is always a very difficult problem to solve. In this paper,the temperature stress due to sunlight, season variation and in -and-out temperature difference is discussed for the large diameter R. C silo. In the meantime,the value and calculating method of the temperature stress for design is also presented.
