Structural design of folding house and analysis of wind load performance

Building upon established typologies of foldable housing, a novel telescopic and foldable structural design has been proposed. To ensure compliance with structural response requirements during deployment and to assess interactions with external wind fields, a detailed finite element model of the foldable structure subjected to wind loading is developed. This model facilitates the analysis of wind-induced responses and pressure distributions under varying wind speeds, ranging from level 5 to level 10, and wind directions of 0°, 45°, and 90°. Furthermore, structural behavior under combined loading conditions, including wind and snow, as well as under extreme environmental scenarios, is evaluated to assess the reliability, stability, and safety of the modular components. The analytical results reveal that wind direction exerts a relatively limited influence on equivalent stress, while the magnitude of the applied load significantly governs the stress response. Under full-load conditions, variations in wind speed yield only minor changes in equivalent stress values. In all analyzed scenarios, peak equivalent stresses consistently occur at the corners where the structural frame interfaces with the hinge components. With respect to displacement, the applied load exerts a more substantial influence than wind direction when wind speed is constant, whereas wind speed becomes the more dominant factor when the overall loading condition remains unchanged.
