摘　　要：某中学新建综合楼采用了箱式钢结构模块化建筑和叠箱-底部框架结构体系,其中涉及大跨度转换桁架和多种不规则项。为确保结构的安全性和稳定性,文章遵循抗震性能化设计原则,为结构体系和构件设定了合理的性能目标。通过小震弹性分析和大震弹塑性分析,验证了综合楼结构的抗震性能。此外,还对中震下的关键构件—转换桁架进行了弹性分析。综合分析结果表明,综合楼采用的叠箱-底部框架结构体系能达到既定的抗震性能目标。The newly-built comprehensive building in a middle school adopts box steel structure modular building and stacked box-bottom frame structure system,which involves large-span transfer truss and various irregular items.In order to ensure the safety and stability of the structure,this paper follows the principle of seismic performance-based design and sets reasonable performance goals for the structural system and components.Through the elastic analysis under small earthquake and elastic-plastic analysis under large earthquake,the seismic performance of the comprehensive building structure is verified.In addition,the elastic analysis of the key component transfer truss under moderate earthquake is also carried out.The comprehensive analysis results show that the stacked box-bottom frame structure system adopted in the comprehensive building can achieve the established seismic performance goal.
