Three-Dimensional Effects in Progressive Collapse Modeling

This paper highlights the importance of accounting for three dimensional effects when modeling progressive collapse behavior. Two types of nonlinear, inelastic models are first presented: 1) a planar comprised of beam-column elements to represent key structural members, and 2) a 3-D model that accounts for the most important components of the building. After validation, the simulation models are exercised to investigate system robustness when columns are forcibly removed. The importance of 3-D effects is quantitatively investigated through comparisons of system responses captured by the planar and 3-D models. In addition, the effect of modeling the slabs is demonstrated by comparing the responses of a 3-D model without slabs and the same 3-D model, but with slabs. It is shown that the slab plays a crucial role in progressive collapse response.
