［摘要］简述拟建的一栋多层钢结构模块建筑的工程概况，根据模块尺寸的限值以及建筑要求等对结构体系进行了选型，提出了钢结构模块与钢框架复合结构体系，并对采用的构件以及节点进行了设计。根据实际受力情况，对节点进行了简化，并对简化方式进行了研究。通过对模块建筑与传统钢框架结构进行对比发现，可以将传统钢结构的设计方法应用到模块建筑中。采用有限元软件MIDAS/Gen821建立了分析模型，在各种荷载及工况组合下对结构进行了分析计算，并将得到的应力、位移等结果与相应的规范进行对比，计算结果表明各个指标均满足规范要求。最后对模型进行弹性时程分析的补充验算。［关键词］多层钢结构; 模块; 复合建筑设计; 节点中图分类号：TU318,TU391 文献标识码：A 文章编号：1002-848X(2016)10-0095-06
Structural design and analysis of multi-storey steel structure module and steel frame composite structuresZhang Pengfei1, Zhang Xizhi2, Liu Jiadi1, Chen Zhihua1,3(1 School of Civil Engineering, Tianjin University, Tianjin 300072, China; 2 Architectural Design and Research Institute of Tianjin University, Tianjin 300073, China; 3 Key Laboratory of Coastal Structures in Civil Engineering and Safety, Ministry of Education, Tianjin University, Tianjin 300072, China)Abstract: The project overview of a multi-storey steel structure module building was briefly introduced. Considering the limit size of module unit and the functional demands, the structural system was selected and the steel structure module and steel frame composite structural system were put forward. The designs of adopted steel member and joint were discussed. According to the actual working situation, the joint was simplified and the simplified method was studied. Through the comparison of the module structure and the traditional steel frame structure, it can be found that the design method of traditional steel structure can be applied to the module structure. The finite element analysis software MIDAS/Gen821 was used to establish the analytical model and the structure was analyzed and calculated under various load cases and working condition combinations. The obtained results of stress and displacement were compared with relevant codes and the calculating results show that all indices can meet the requirements of codes. Finally, the supplementary checking for elastic time-history analysis of the model was carried out.Keywords: multi-storey steel structure; module; composite structure design; joint
