Progressive Collapse Analysis of RC Structures Including Beam Axial Deformation
Publication: Structures Congress 2011
Abstract
Effects of beam growth in progressive collapse resistance of an actual eleven-story reinforced concrete structure are evaluated following predefined initial damage. The initial damage was caused in part by simultaneous explosion (removal) of four adjacent columns, two of which were exterior columns. In addition to the removal of these columns, two beam sections were also exploded. The structure resisted progressive collapse following such severe initial damage. An analytical model of the structure accounting for the interaction between the axial and flexural deformations is developed to study progressive collapse resisting mechanisms. The analytical results show good agreement with experimental data. The main progressive collapse resisting mechanism was the flexural-axial interaction of the second floor deep beams. The Vierendeel frame action of the floors above also contributed to collapse resistance.
