Abstract
As a result of several high-profile terrorist attacks against buildings in recent
years, mitigating progressive structural collapse has been of particular interest to
the structural engineering community. Previous research studies have focused on
the impact of an individual column failure on the overall stability of a structure.
These studies have relied mostly on computational investigations and
experimental tests on individual components. Few studies have been done to
predict the behavior of floor slabs above a failed column, and the computational
tools used have not been validated against experimental results. The research
program presented in this paper extends prior work in this area by testing
specimens that include all structural components of a typical floor system in a
prototypical steel-framed structure. In total, six full-scale tests will be performed,
including three interior 2-bay × 2-bay specimens and three exterior 2-bay × 1-
bay specimens. In all tests, the mid-span column will be removed statically while
the slab is loaded with the recommended extreme event design load. The slab
consists of corrugated decking with lightly reinforced concrete on top that is
connected to the floor beams through shear studs and is consistent with typical
