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 without beam vaulted, therefore, the Galaxy roof structure itself than normal steel fire performance. Moreover, because the internal structure of the Galaxy roof girder arch clearance large non-plant, the ground is not easy to reach the roof of fire, according to architectural design code for fire protection without 梁拱安 installed, the roof can also do fire treatment. September 1998 China Association for Engineering Construction Standardization Association issued a standard "arched corrugated metal roof structure Technical Specification" preparation plan. Light steel structure under the auspices of the Association Committee, the editor of the unit Tianjin University and various rationality nearly five years of hard work, finally completed the preparation tasks.
