［摘要］天津子牙尚林苑白领公寓项目属于多层模块建筑，根据模块单元的尺寸、建筑功能和结构要求对模块单元进行选型，选用了钢模块与钢框架的复合结构体系。为便于模块单元间的连接和安装，提出了一种新型的角件旋转式模块单元间连接节点。根据实际节点受力情况，在MIDAS/Gen中对节点进行简化，采用偏安全的方式进行了结构的整体设计与分析，在各种荷载及工况组合下对结构进行了分析计算，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，结构各项指标均满足规范要求。最后对模型进行了弹性时程分析的补充验算，并参考弹塑性时程分析的结果设计连接件的尺寸，保证了结构的安全。

Abstract:The white-collar apartment project in Ziya Shanglin Garden of Tianjin is a multi-story module building. According to the sizes of the module unit, architectural functions and structural requirements, the module units and the composite system of steel module and steel frame were selected. In order to facilitate the connection and installation of modules, a new kind of connecting joint between rotating corner module element was proposed. According to the actual mechanical situation of module joints, the finite element analysis software MIDAS/Gen was used to simplify the joints. The overall design and analysis of the structure were carried out in a partially safe way, and the structure was analyzed and calculated under various loads and working conditions. The results of stress and displacement were compared with the corresponding codes. The calculation results show that all the indexes of the structure meet the requirements of the code. Finally, the model is checked by elastic time history analysis, and the size of the connector is designed according to the results of elastic-plastic time-history analysis, which ensures the safety of the structure.
