摘要
结合工程实例,确定某超长混凝土框架结构在温差作用下的温度荷载,利用有限元方法分析该结构在温差作用下的收缩效应,获得本工程的温度应力分布规律及数值并提出有针对性的加强措施。
In combination with practical design,the temperature load of an overlong concrete frame structure is ensured; also temperature and shrinkage effects of the structure were analyzed by using finite element method.The distribution of temperature stress and the value was obtained.Targeted measures were introduced.
