【摘要】：当今世界，随着经济与科学技术的飞速发展，越来越多的大跨度体育场馆开始涌现，而且对建筑造型和使用功能的要求也越来越高。由于现代体育场馆的很多自身特点，导致该类建筑结构抗震设计及钢结构屋盖与下部混凝土主体结构整体协同作用分析计算方面存在很多难点。尤其在高烈度地区，这些难点更为明显，因此，针对大跨度体育场馆的抗震性能研究更为重要。本文以巧家县体育馆的抗震设计工程实例作为研究对象，从大跨度空间混合结构的概念设计和结构选型出发，并以近年来多次地震受灾区的工程实例为依据，阐述结构概念设计在体育场馆类抗震设计中的合理运用。针对建筑结构抗震设防专项审查部门提出有关下部混凝土主体结构支座处刚度局部集中对上部钢结构支座反力产生影响的建议，本文通过对下部混凝土主体结构采用框架结构和框架剪力墙结构两种不同结构体系进行整体计算，比较分析其抗震性能，并对一系列相关抗震分析问题进行总结，，提出方案优化建议。针对大跨度体育场馆结构抗震设计过程中平面及扭转不规则导致周期比与位移比控制难度大，钢结构与下部混凝土主体结构整体计算模拟不真实，错层构件及节点受力分析复杂等问题，本文通过采用通用有限元结构分析软件MIDAS GEN对不同结构方案进行抗震性能分析，并结合实际工程设计经验进行归纳总结，作为日后类似工程的设计参考依据。
[Abstract]:In today's world, with the rapid development of economy and technology, more and more large span sports venues began to emerge, and the construction of shape and function requirements are increasingly high. Because many modern stadium's own characteristics, resulting in synergistic effect of this kind of building structure seismic design and overall roof and the lower concrete main steel structure there are many difficulties in calculating structure analysis. Especially in areas of high intensity, the difficulty is more obvious, therefore, the study on seismic performance of long-span stadium is more important.
In this paper, the seismic design project of Qiaojia County Stadium as the research object, starting from the selection of concept design and structure of large-span space hybrid structure, and several times in recent years, the quake affected project as the basis, elaborated the rational use of conceptual design in class stadiums in seismic design. According to the structural seismic fortification special review the relevant department proposed the lower concrete structure of main bearing stiffness on the local concentration of upper bearing steel structure anti impact force recommendations, based on the concrete main structure adopts frame structure and frame shear wall structure with two different structure system of the overall calculation, comparative analysis of the seismic performance, and a series of related problems of seismic analysis summary of proposed optimization recommendations.
For the planar seismic response of long span stadium structure design process and lead to irregular torsion period ratio and displacement ratio control is difficult, the overall steel structure and the concrete main structure simulation is not true, Cuoceng member and joint stress analysis of complex problems by using finite element analysis software MIDAS GEN to different structure scheme the seismic performance analysis, and combining with the practical experience of engineering design are summarized, as a reference for the design of similar projects on.
