Abstract:
When exposed to fire, high-strength concretes experience faster degradation of strength and stiffness than normal-strength concretes, and they are more susceptible to fire-induced spalling. Experimental and numerical fire resistance studies on structural members comprised of normal- and high-strength concrete are described, fire performance factors are listed, and recommendations on enhancing fire performance of high-strength concrete members are provided.
