摘要
针对目前广泛使用的插入式墙板轻型活动房,采用ANSYS软件对一典型活动房进行整体三维有限元分析。特别地,在对插入式墙板与框架的协同工作原理进行探讨和分析的基础上,提出一种分步叠加法实现了在考虑插入式墙板抗侧作用问题上的合理性和可行性,意在进一步保证这类结构在经济情况下的安全性和可靠性。结果表明:插入墙板后活动房的整体受力变形性能将获得极大改善,但插入式墙板安装缝隙的大小对结构的受力有较大影响,因此在采用更经济的构件截面的同时必须确保活动房的安装质量,以保证墙板发挥预期的抗侧作用。
The inserted wallboard light moving house is widely used at present. In this study, the three-dimensional finite element analysis of a typical moving house is performed. In particular, based on the analysis of the cooperative principle between the insert wallboard and frame, a step-by-step superposition method of considering the lateral resistance effect of inserted wallboard is developed. Therefore, the safety and reliability of the structure can be further ensured when the project budget is limited. The results show that the global force deformation performance of a light moving house is greatly improved after the wall panels are inserted, whereas the size of the installation gap greatly affects the structure stress. Therefore, accurate installations of a light moving house must be ensured when more economical member sections are employed to make the wallboard provide expected lateral resistance.
