Design of steel structures for blast-related progressive collapse resistance

Structural design of steel structures in buildings to resist the effects of potential blasts is discussed. Steel building systems are found to be ideal due to the toughness of structural steel as a material and the relative ease of designing steel structures with adequate redundancy, strength and ductility to redistribute loads and arrest collapse. Moment-resisting steel frames are found to be ideal for the continuity of structural systems and in avoiding progressive collapse. A building with a continuous moment-resisting steel frame on each line of columns can resist collapse through redistribution of load to adjacent columns.
