某实际超长结构温度应力分析

Analysis of Temperature Stress in the Super-length Reinforced Concrete Structure

超长钢筋混凝土结构温度应力分析一直是设计人员所关注的课题。文章结合工程实例对超长结构温度应力进行分析,提出了温差的取值方法,并采用PMSAP有限元软件对超长结构进行计算,分析其变形和内力特点,总结出了设计中减小温度应力的措施。

Analysis of temperature stress in the super-length reinforced concrete structure is one of the most important problem to the engineers. In the paper,on the base of calculating the super length structure by finite element method,analyzing the deformation and stress in the structure,some methods beneficial to diminish the temperature in structure has been gained.
