超长斜交梁钢屋盖温度效应控制措施探讨

On exploration for controlling measures for temperature effect of super-long skew girder steel roof

以实际工程为背景,介绍了超长斜交梁屋盖的结构形式,讨论了此类结构在温度作用下的特性,在已有分析成果[6]基础上,针对斜交梁钢屋盖的特点,探讨了控制温度效应的措施,并运用通用有限元软件ANSYS建立分析模型,以季节温差作为温度荷载,进行相应措施下的温度应力分析,以期为此类屋盖梁系的深入研究和设计提供指导。

Based on the factual projects,the paper introduces the structural forms of the super-long skew girder steel roof,discusses the features of the kind of structure in the effect of the temperature,explores the measures for controlling the temperature effect according to the features of the super-long skew girder steel roof based on the analysis results[6],establishes the analyzing model by adopting ANSYS,the general finite element software,and has the temperature stress analysis by taking the temperature differences among seasons as the temperature loading,so as to provide the direction for the further research and design of the roof beam system.
