Mitigation methods of progressive collapse for a 10-story reinforced concrete structure

Progressive collapse in a structure occurs when major structural load carrying members are removed suddenly, and the remaining structural elements cannot support the weight of the building and fail. This failure usually occurs in a domino effect and leads to a progressive collapse failure in the str...

Mitigation methods of progressive collapse for a 10-story reinforced concrete structure
description Progressive collapse in a structure occurs when major structural load carrying members are removed suddenly, and the remaining structural elements cannot support the weight of the building and fail. This failure usually occurs in a domino effect and leads to a progressive collapse failure in the structure. A building must have sufficient strength, ductility and redundancy to resist collapse and ensure life safety. Extreme loading events, such as earthquakes and explosions, may cause severe local damage that triggers a chain reaction of large-scale structural failure or progressive collapse such as in the Oklahoma City building and the World Trade Centre. The bombing of the Murray Federal Building in Oklahoma City is a typical example of progressive collapse failure. The initial bomb blast caused only 10% of the structure’s damage, and the resulting progressive collapse failure lead to 90% of the structure’s damage. This thesis investigates the potential to fail of a 10 story Reinforced Concrete building due to progressive collapse. The modelling and analysis are performed by ETABS 9.5 software.
