The paper investigates the contribution of floor systems to improving the progressive collapse  resistance of multi-story frame buildings following loss of a column. Composite action and  diaphragm effect of slab are taken into account by considering the interaction between  concrete slab and steel girders. Applied Element Method through nonlinear static and  dynamic analyses is applied to predict the structural response after the loss of a column.  Robustness criteria are intended to be obtained taking as reference the ratio of failure load to  the nominal gravity load.
