The lack of strong, stiff connections between the perimeter frames and the floor system may result in minimal resistance to out-of-plane motion by the perimeter frames and may lead to unstable behavior when perimeter frames are separated from the floor systems as a result of accidental or earthquake loading. To investigate this behavior, simulations of the progressive collapse of these systems were carried out using simple structural models. Structural stability was evaluated by conducting eigenvalue analysis at each time-step of the analysis. The results of this study show that when frame-floor connections have insufficient tensile strength, progressive collapse of perimeter frames occurs due to out-of-plane motion of the frames and that on-set of collapse may be predicted by a negative instantaneous eigenvalue.
