Capacity Test And Finite-element Analysis Of Extendable Container Mobile House

In order to accelerate and industrialize construction, mobile house appeared since the 2th World War as a new style structure. Because of the merits such as high-grade industrialized, high speed of construction and good construction physical properties (seismic resistance, thermal retardation, noise isolation, water-resistance), the mobile house is widely adopted for civil and military use. The extended container mobile house can be repetitively disassembled and assembled. Colored steel Polyurethane composite sandwich boards and 1C second generated container consolidates this kind of semi-temporary buildings. The house can be used for field encamping, field direction and medical treatment.In this paper, the half model of the mobile house is adopted, and its capacity under wind load and snow load are researched. Based on the equivalent principle of mechanics, the wind and snow loads are applied as multi-point loads and line-distributed loads. The loaded models were analyzed and the weak areas were found. Do the loaded analysis and Push-over analysis with SAP2000. The analysis results were compared with that from experiment.The result indicated that The stress and displacement of the house in the experiment was in the elastic range, the design of the house is ratinal, the capacity of the mobile house met the design requirement. The house can bear 10 calss wind load and 20cm snow load. The wind load determinated capacity of the mobile house. Push-over indicated the building collapsed because of the local failure. The result of analysis was consistent with that of experiment.
