When a floor falls onto the floor below, the impulse transmitted to the lower system results in considerable deformation in the impacted floor. In this paper, a linear static progressive collapse analysis procedure was developed considering the impact of failed members. The impact loads computed from various simplified methods were calibrated with FEM analysis results. The analysis procedure was applied to a moment frame and a braced frame, and the results were compared with those obtained without considering impact load.
