装配式集装箱结构体系优化及节点性能

为建立装配式集装箱结构的标准体系并掌握其力学性能,以一个典型的集装箱建筑方案为基础,以规范要求为评价指标,对其进行了6种不同结构方案的静力分析和抗震分析,研究了设置横梁立柱、辅助拉杆等构造措施对结构性能的影响,结果表明:该集装箱建筑体系对风荷载较为敏感,构件截面主要由风荷载控制,地震作用不起控制作用,增加局部立柱和横梁对于提高集装箱建筑的抗侧移刚度作用不明显,而设置侧向拉杆则能有效加强结构抗侧移刚度.最后采用多尺度分析方法对结构所采用的装配式集装箱建筑节点进行了模拟分析,结果表明该节点在结构各种工况下均能保持良好的工作状态,可为类似集装箱建筑的节点选用提供技术参考.

System optimization of fabricated container structure and the joint performance

To establish standard system of fabricated container structure and obtain its mechanical characteristics, static mechanical analysis and seismic analysis were made on six sets of structures according to existing codes based on a typical plan of container building. The influence on structural performance by adding beams and columns or tension cables was also studied. The results indicate that: container building system is sensitive to wind load, which controls the section of members and seismic action is not a dominant factor; the effort to enhance lateral stiffness of container building by adding local columns and beams is not useful, while adding lateral tension rod can strengthen the structural lateral stiffness effectively. Finally, a connected joint used in container building was analyzed by multi-scale analysis. The results indicate that this joint can work well under every working condition and provide a technical reference of joint selection in similar container buildings.
