No girder arch Fire: Galaxy roof as a continuous shell, belongs to the high-order super-static structure, in case of a fire can occur after redistribution of internal forces, delaying structural damage, so the Galaxy roof structure itself better than the average of fireproof performance. Moreover, because the internal structure of the Galaxy headroom big no roof beams vault, floor flames difficult to reach without beam arch roof material, according to the architectural design code for fire protection, the roof can also do fire treatment. Because there is no clearly defined design rules without beam arch plant, almost no relevant research, and its mechanical behavior is still unknown; in addition, in the design of arched corrugated steel roof substructure column when considering how arched corrugated steel roof of capitals bearing stiffness is also troubled by a problem the engineering sector. No girder arch, Guangxi Yinhe, without beam vaulted provided by Guangxi Yinhe Metal Structure Engineering Limited.
