Abstract
The project summarized here was the third phase of a three-phase research and development project.
Phases 1 and 2 focused on new buildings while the third phase, discussed in this paper, was primarily on
retrofit of existing buildings. The two main objectives of these studies were:
1. To establish inherent strength of typical floor framing systems in steel structures to resist
progressive collapse in the event of removal of a column by a bomb blast and;
2. To develop and test cable-based mechanisms that can be used to prevent progressive collapse in
the event of removal of a façade column.
For new construction, the mechanism to prevent progressive collapse consisted of placing a series of four
1-1/4" diameter cables inside the floor RC/Steel deck slab and anchoring the end of the cables to braced
or shear wall bays. A version of this system was used by MKA (formerly SWMB) of Seattle in General
Services Administration buildings. For existing buildings, the full scale specimen used in the tests
