上海某售楼部模块化结构设计与分析

The design and analysis of modular structure for a sales gallery in Shanghai

为研究地震作用下上海某模块-钢框架混合结构售楼部的受力特点,首先介绍了结构方案布置,并阐述了分析模型的建立过程,然后基于计算结果对结构的地震响应进行深入分析;最后讨论了项目设计难点并给了应对措施。结论如下:结构分析时应根据分析侧重点不同选用相应的建模方式;模块单元之间的水平和竖向连接均可采用铰接假定;设计过程应充分考虑施工工艺影响以便模块箱体的顺利安装;设计满足规范“三水准两阶段”的抗震性能目标。

In order to study the mechanical behavior of model-frame mixed steel structure for a sales gallery in Shanghai under seismic reaction,the process of setting structural layout and building analytical model is introduced in this paper.The structural arrangement and the modeling process has been introduced firstly.Based on the computed result.seismic response of the structure has been analyzed profoundly and measurement to overcome the design difficulty has been discussed.It can be concluded that structural modelling must match different research purposes and content.In addition,hinge joint assumption for horizontal and vertical can be made between the adjacent boxes of modular structure.Moreover,the influence of construction technology should been considered fully in design process so that construction can be carried out smoothly.Most importantly,design conducted in this paper is proved to fulfil the performance objectives for seismic fortification based on Chinese codes“three levels&two stages”.
