In the present paper a procedure for the assessment of the residual strength of R.C. structural members after a fire is proposed. The procedure has been applied to the evaluation of the load bearing capacity of a storage and apartment building which experienced a real fire. The damage provoked by the fire was evaluated through a survey and an experimental campaign carried out using non destructive techniques. Then, the analytical assessment of the residual strength using a simplified fire model based on the zone method was performed. On the basis of the analysis results, a retrofitting programme was defined, with the aim at restoring completely the serviceability of the building.

Abstract
In the present paper a procedure for the assessment of the residual strength of R.C. structural members after a fire is proposed. The procedure has been applied to the evaluation of the load bearing capacity of a storage and apartment building which experienced a real fire. The damage provoked by the fire was evaluated through a survey and an experimental campaign carried out using non destructive techniques. Then, the analytical assessment of the residual strength using a simplified fire model based on the zone method was performed. On the basis of the analysis results, a retrofitting programme was defined, with the aim at restoring completely the serviceability of the building.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
