Movable B&B hotels, non-standard accommodation, RV campsites, Internet celebrity restaurants (design, construction)21

The steel structure house should be designed with a single slope, and the drainage direction should not be directed towards the main structure. Attention should be paid to the connection between the outer wall of the main structure and the roof of the roof. Make sure that the outer wall of the main structure is drained smoothly without leakage. As a sub-structure, the span of the hut is generally smaller than that of the main structure, and it is usually hinged with the main structure, as shown in (Fig. 1); Relevant regulations fully consider the effect of snow accumulation at the connection between the hut and the main structure; for the main rigid frame column connected with the hut, the adverse effect of the shear force generated by the hut should be fully considered in the design. In the design, some people think that since the hut is a sub-structure, the sub-structure (the simply supported beam between the two cantilever beams) can be separated from the main structure (the cantilevered beam on both sides of the simply supported beam) like a multi-span statically indeterminate beam. To calculate, in fact, these two situations are different: one is a statically indeterminate structure, the other is a statically indeterminate structure, the load acts on the main structure of the multi-span statically indeterminate beam, does not affect the deflection and internal force of the substructure, only The displacement and internal force of the main structure can only be affected by the load acting on the substructure, so the displacement and internal force of the substructure can be calculated first, and then the influence of the substructure on the displacement and internal force of the main structure can be considered; while the load (vertical load or horizontal load) ) acting on the main structure (super statically indeterminate structure) of a single-storey portal rigid-frame house with a draped house will affect the displacement and internal force of the substructure (draped house), therefore, regardless of whether the load acts on the main structure or on the On the sub-structure, they should be analyzed and calculated as a whole. Regarding the snow pile effect at the connection between the hut and the main structure, Paragraph 5 of 'Code for Loading of Building Structures': 'Generally, there is wind vortex effect on the high and low roof, snow piles The accumulation of curve figures is often formed. The 'Code for Loading of Building Structures' simplifies it as a snowdrift with a rectangular distribution. In the heavy snow in Liaoning in March 2007, the seriousness of the snow pile effect problem has been fully explained; in addition, there is a problem of skiing effect from a high place to a low place, and there is no corresponding calculation formula given in the Chinese regulations. , should be fully paid attention to in the design.
