Abstract:
Box - type modular building with advantages of quick installation, good comfort, beautiful appearance and convenient turnover, is widely used in construction of temporary construction, business services, holiday villas and other projects. In this paper, a single span double - layer box - type modular building in Shenzhen was taken as an example, using modular building system with a special-shaped corner column and cold-formed thin-walled beam. The finite element software ANSYS was used to calculate the overall structural strength and stiffness, and the stress and displacement calculation results under the control of vertical load and horizontal wind load were respectively given. The results show that under the snow load, the maximum stress of the whole structure is 163.14MPa, which appears in the middle of the second layer top frame purlin. Under the horizontal wind load, the maximum stress of the whole structure appears at the beam-to-column connection panel, and the stress of the first story is more unfavourable than that of the second one. The maximum displacement in the horizontal direction is 10.37mm. The maximum displacement angle between layers is 1/278. The above calculation results all meet the requirements of “Standard for design of steel structures” (GB50017-2017), which can ensure the safety and reliability during normal use. Furthermore, it can provide reference for the design and optimization of multi-storey box buildings.
