The purpose to use Dynamic Application factor is to design and analysis the building and structures more efficient under the progressive collapse where one can only use only the Linear Static Analysis and times the results by the DAF instead of using more complex Linear Dynamic Analysis. It is suggested in the code that Dynamic Amplification Factor should be 2 to account for the all the dynamic effect, however, the simulation from this paper suggest otherwise. Throughout the four case analysis in this paper, none of them has more than half of the design members with qualified Dynamic Amplification Factor which suggests that the current code has failed to predict a efficient loading condition for one to analysis the building under the progressive collapse condition.
