Effect of concrete strength and thickness of flat slab on preventing of progressive collapse caused by elimination of an internal column

Designing structures against progressive collapse is an important part of the building design. However, some guidelines such as GSA and UFC holds implications for reducing the risk of progressive collapse of structures, but because the nature of the loads or events that cause damage are not well def...
