摘要(Abstract):

第七届世界军运会主赛场主体结构采用钢筋混凝土框架结构,屋盖采用车辐式索承网格钢结构,为了保证屋盖结构受力安全合理,主体结构设计尤为重要。由于桩基持力层不同,需对基础不均匀沉降进行分析,发现差异沉降过小可以忽略其对屋盖和主体的影响。在进行主体结构设计时,重难点问题主要体现在屋盖对主体结构的影响和超长结构的分析两个方面。通过计算分析,屋盖对主体的影响主要为支承屋盖的框架柱和下一层相邻跨梁板;超长结构温度收缩问题可以通过合理考虑施工方案和采取有效措施,达到减小温度应力和节约工期的目的。
The main structure of the main stadium of seventh World Military Games adopted reinforced concrete frame structure,and its roof adopted cable supported lattice structure. In order to ensure the safety and rationality of the roof structure,the main structure design is particularly important. Because the bearing strata of pile foundation are different,it is necessary to analyze the uneven settlement of foundation. If the differential settlement is too small,the influence on roof and main structure could be neglected. The key and difficult problems of main structure design were mainly reflected in the influence of the roof on the main structure and the analysis of the super-long structure. Through calculation and analysis,the main influence of roof on the main structure is the frame column which supported the roof and the adjacent beam slab of the next floor. The analysis of super-long structure could be carried out through reasonable consideration of construction scheme and effective measures,which could reduce temperature stress,saving time and cost.
