Influence of Various Initial Side-Column Damages on the Horizontal and Vertical Mixed Progressive Collapse Behavior of RC Planar Frames

Abstract

AbstractBlast loads not only cause the single key column failure of reinforced concrete planar frames, but also simultaneously introduce damage to other adjacent members. By conducting quasi-static test on a 1:3 scaled-down specimen of a RC planar frame ...Practical ApplicationsNeglecting the force and deformation of side columns during the collapse process would overestimate the collapse resistance of reinforced concrete planar frames. By removing the side-column constraints, this paper considered the ...
