The superiority of Chengdu steel structure is reflected in where
Chengdu steel structure usually in the temperature of 450 ~ 650 °C will lose the bearing capacity, large deformation, resulting in steel columns, steel beams bending, as a result of excessive deformation can not continue to use, generally unprotected Chengdu steel structure fire resistance limit of about 15 minutes. The length of this time is also related to the speed at which the component absorbs heat.
