摘　　要：以东营会展中心工程为背景,运用有限元程序ANSYS建立正、斜交网格超长屋盖结构模型,考虑季节温差,分析比较两种屋盖体系在温度效应上的差别,归纳斜交网格屋盖结构温度效应的特点。联系工程实际,提出斜交网格屋盖结构的设计要点及构造措施,所得结论为类似结构的深入研究和设计提供参考。Based on the project of 'DongYing Meeting and Exhibition Center',super-long orthogonal-crossing and diagonal-crossing grid roof structure models were established by ANSYS.Considering season temperature variation,the differences between these two kinds of roof structures were compared and temperature effect on the diagonal-crossing roof structure was analysed.At last,based on the actual engineering project,some suggestions were proposed to provide the reference for the research and design of similar structures.
