Abstract: This paper presents a simplified model to evaluate progressive collapse response of steel beam–column substructures in a midspan column removal scenario. The model accounts for the influence of the span:depth ratio of the ...

Abstract: A building experiences progressive collapse when a primary structural element fails, resulting in the failure of adjoining structural elements, which in turn causes further structural failure. The final failure contains ...

Abstract: This paper studies the behavior of concentrically braced frames (CBFs) and eccentrically braced frames (EBFs) under a progressive collapse scenario, by using the alternate load path method, recommended in progressive ...
