| Abstract: | Based on the design process of D0D 2009, examples were provided for the progressive collapse pre- vention design of Chinese frame structures. Using the software SAP2000 of finite element conduct progressive col- lapse analysis for 12 layers of reinforced concrete by alternate path method. Using the nonlinear dynamic analysis to study the progressive collapse resistance. The internal force of key member before and after the removal of the col- umns were compared. Conducting corner and side columns for progressive collapse analysis of the destructive effects. |
