Abstract: A computational methodology is presented for evaluating structural robustness against column loss. The methodology is illustrated through application to RC frame buildings, using a reduced-order modeling approach for ...

Abstract: This paper presents a computational investigation of two reinforced concrete beam-column assemblies, each comprising three columns and two beams, subjected to monotonically increasing vertical displacement of the unsupported ...

Abstract: Current methods and practices for modeling and numerical simulation of disproportionate collapse of reinforced concrete (RC) frame buildings are reviewed. Modeling advances at the component, connection, and system levels ...

Abstract: To investigate the load-resisting mechanisms and responses of typical steel–concrete composite frames under the progressive collapse scenario, a 2×1 bay full-scale steel–concrete composite floor system was quasi-statically ...

Abstract: This paper presents an experimental and computational assessment of the performance of steel and reinforced concrete beam-column assemblies under monotonic vertical displacement of a center column, simulating a column ...

Abstract: Since the events of September 11, 2001, the engineering community has devoted increased attention to evaluating the vulnerability of multistory buildings to disproportionate collapse, including substantial research and ...

Abstract: The potential for progressive collapse of a typical reinforced concrete (RC) moment frame structure initiated through the loss of one or more first-story columns is numerically simulated using a macromodel-based approach. ...
