| Abstract: | The definition of the structural progressive collapse in case of fire is presented.The structural characteristics in case of fire are analyzed and the judgment process of structural progressive collapse is given.On the basis of introduction of commonly used analysis and design methods of structural progressive collapse,a design idea for preventing structural progressive collapse in case of fire is put forward by means of nonlinear static analysis in alternative path method. |

| Keywords: | effects of fire structural progressive collapse alternative path method nonlinear static analysis |
