The gable wind-resistant columns can be designed according to the conventional design. Under normal circumstances, the metal arch corrugated roof project should be closed. In the open or semi-open situation, due to the uncertainty of the wind load of the roof and the substructure, the connection between the metal arched corrugated roof and the substructure is generally hinged or fixed. According to the simplified calculation model, the design of the substructure is much simpler compared to the conventional structure. The ring beam, column (wall) and foundation of the lower structure are designed according to the bearing reaction force calculated by the upper arch corrugated steel roof structure analysis, and the whole structure can be simplified as a series of statically indeterminate members for analysis, calculation and design.
The arched corrugated steel roof situation is more complex and difficult to predict. At this time, part of the gable above the ring beams at both ends of the roof should be closed, and wind-resistant columns should be set up if necessary. On the one hand, it can beautify the architectural effect of the roof, and more importantly, it increases the overall stiffness of the roof and increases its wind resistance.
Such as the waterproof and anti-corrosion treatment of the arch foot point of the arched corrugated steel roof structure, the setting of the lighting belt and the ventilation cap and the node treatment, thermal insulation, lightning protection and fire prevention, etc.
