| Abstract: | For the characteristics of unexpected events as earthquake and terror assault that may cause secondary fire to large-scale building,the difference of fireproof capability of large scale structures and general buildings is compared.By use of axial inhomogeneous temperature strain model,the fireproof function and structure fire-resistance of large structures are calculated and analyzed.Some characteristics of fireproof performance are summed up.A set of theoretical methods for calculating fire resistance of structures are presented. |

| Keywords: | unexpected event secondary fire large-scale structures component fire-resistant design non-uniform temperature distribution |
