Abstract	超高、大跨厂房结构受力复杂，为保证其安全可靠，选择合适的结构型式，并对其进行抗震性能分析，是非常有必要的。拟建的某超高大跨单层厂房净空间不小于260×100×100m，两端大门尺寸不小于70×70m，属于超高、大跨、空旷建筑，其下部支承结构和屋盖结构的合理选型将对该厂房的安全、经济性产生重大影响。本文以该厂房为工程背景，针对该建筑的结构选型和抗震性能分析做了一系列工作：进行了以抗侧力体系为核心的结构选型，给出推荐方案，进行了推荐方案结构在多遇和罕遇地震下的抗震分析。通过这些工作主要取得了以下结论： 1.根据该工程超高、大跨、开大门洞的要求，提出了7大类12个结构方案，并对各个结构方案进行了计算分析，通过对结构变形、内力、材料用量以及施工难度进行比较，提出了钢管混凝土框架-支撑-混凝土筒体混合结构的推荐方案。 2.对推荐结构方案进行了多遇地震作用下的弹性时程分析，结果表明结构整体位移处于合理范围内，该结构方案可以满足“小震不坏”的性能要求。 3.对推荐结构方案进行了罕遇地震下的弹塑性时程分析，结果表明结构的弹塑性层间位移角满足要求，结构在罕遇地震下仍具有较强的承载能力和较小的层间位移角，该结构方案能够满足“大震不倒”的要求。
Other Abstract	We will build an factory , the net space will not less than 260 × 100 × 100m(L×W×H)，and the doors in the end walls will be not less than 70 × 70m(W×H). This paper is based on the building，do a series of work for the selection of structural and seismic performance of the building: The following achievements have been gotten: Firstly, prepared 12 structural alternatives of 7 kinds，and analysis them at same height，same span，same load and operating conditions. And compared structural deformation，internal forces，material consumption，as well as construction difficulties . At last，come to concrete filled steel tubular framework - support - concrete cylinder hybrid structure for the better program. Secondly，analysis the structure in a history way: Structural displacement within a reasonable range，indicating that the structure of the project to meet the “minor earthquake” performance requirements . Thirdly，test the seismic performance of the model under rare earthquakes by the elastic-plastic dynamic time-history analysis method: deformation of the structure of the plastic drift angle is able to meet the specification requirements.
