Robustness of Older Flat Plate Buildings against Dynamic Progressive Collapse
This paper assesses the structural robustness of older RC flat plate buildings against progressive collapse. A finite element macro model is employed to simulate the complex nonlinear response of slab-column connections and their punching failures. The model is applied first to a multi-story flat plate building to examine its potential of progressive collapse. An energy-based static pushdown approach is validated for estimating the peak dynamic response. Parametric studies are then carried out to investigate the effects of slab reinforcement ratio, slab thickness and concrete strength on the progressive collapse resistance of flat plates. The dynamic increase factors specified in the current design guideline are examined.
