Fire Situation in Case of RC Members by Sika CFRP Strengthening
Abstract The fire situation aspects especially in case of carbon fiber reinforce polymer (CFRP) strengthening of RC elements are one of major design factor in civil engineering today. Here the next options for CRFP strengthening is discussed. Option A1 when CFRP is not necessary under fire scenario and Option B - FRP is necessary under a fire scenario. Two parameters are related to the fire scenario. First parameter is reaction to fire and second parameter is structural members’ fire resistance. The need for fire protection and fire resistance of RC structural elements is obtained by means of a calculating following a Eurocode procedures. Simplified expected temperatures profiles calculation process is presented. Structural analysis under fire situation of strengthened unprotected and protected member is shown as well. It is concluded that under fire scenario according to Eurocode calculation methodologies the requested fire resistance (R30–R240) can be fulfilled with no additional measure or protection at more than 80–90% of the real cases.
