本文介绍了苏联哈里科夫建工学院最近提出的几种钢筋混凝土结构节约钢材的方法,并且结合我国国情进行了探讨。指出:冷拉Ⅲ级钢筋作为钢筋混凝土梁的配筋,其强度可以得到充分利用,因此减少了钢材用量;采用钢-玻璃钢复合配筋的混凝土结构,可以提高结构的强度、刚度、抗裂性和耐久性并减少钢材的用量;用玻璃钢代替钢筋混凝土结构中的钢筋,是今后节约钢材的重要方向。
This article introduced the methods proposed recently by the Soviet Union’s Harikov School of Engineering and Technology to save steel in several reinforced concrete structures, and explored in combination with China’s national conditions. It is pointed out that: As a reinforcement of RC beams, cold drawn grade III steel bars can be fully utilized, thus reducing the amount of steel materials; steel-glass reinforced composite reinforced concrete structure can improve the strength, stiffness and crack resistance of structures. And durability and reduce the amount of steel; use of glass fiber reinforced plastic instead of reinforced concrete structure, is an important direction to save steel in the future.
