摘要
在讨论了现有温度配筋方法之不足的基础上,指出合理的温度钢筋应采用钢筋混凝土非线性有限元方法,根据使用阶段最大允许裂缝宽度来配置.并运用这一概念对三峡升船机塔柱底部实体混凝土结构的温度配筋进行研究,分析了配筋量与裂缝开展、裂缝宽度之间的关系,确定了合理的温度钢筋用量,并与应力图形法进行对比.
The shortcomings of present temperature reinforcement design methods are discussed in this paper, and a reason-ab1e method in which the temperature reinforcement is determined by RC nonlinear finite element method according to the maxi-mum permissible crack width is presented, and used to determine the temperature reinforcement of mass concrete in tower-columuStructure in the Three-Gorges Ship-lift. And the relationship between the quantity of reinforFement and width of crack is anal-ysed, the reasonable quantity of temperature reinforcement is suggested.
