Reinforced Concrete & Progressive Collapse
Increased concerns about security have refocused the attention of building owners and designers in recent years on the elements of structural design and structural integrity.
Today, designers need to consider blast resistance and progressive collapse in their structural designs.
The basic objective of blast-resistant design is to to mitigate casualties and damages to a structure.
Progressive collapse occurs when a localized failure causes damage disproportionate to original damage. The overall result can be dramatically disproportionate to the initial cause, which may contribute to the number of casualties and trapped survivors.
Experts generally agree that cast-in-place reinforced concrete structures are inherently well-suited for providing solutions to progressive collapse.
In fact, effective strategies for progressive-collapse mitigation often can be easily carried out with relatively simple design modifications to the overall structure combined with close attention to the structural detailing of concrete reinforcement.
