Damage assessment of concrete structures exposed to fire [PDF]

open access: yes, 2013
During a fire, concrete structures behave in most cases very well. It could therefore be of economic interest to repair the damaged structures, as costs for demolition and rebuilding can be avoided and the building can be reused faster.
