Abstract:
To prevent progressive collapse, structures should be designed and detailed with an adequate level of continuity, redundancy, and ductility so that alternative load paths can develop following the loss of an individual member. This article illustrates the inherent reserve capacity of seismically detailed reinforced concrete moment-resisting frames that make the system an excellent first step in designing to prevent progressive collapse. As demonstration, a study was conducted on a simple 12-story RC frame building representative of existing construction and designed to the older requirements of the Uniform Building Code.
