Abstract:

This study covers a comparison of fire protection performance efficiencies of two commercially available different intumescent coatings on two 1-meters steel beams which have S275 steel grade and  UPN 200 steel sections for 2 hours by following ISO 834 fire curve in a furnace in the Turkish Standards Institute (TSE) laboratory. Each beam was insulated with different industrial intumescent coatings to explore the efficiency of these intumescent coatings. Hence, all variables containing workmanship quality, period of application of intumescent coatings, steel grade, steel sections, furnace type, fire type, and period of the experiment were kept constant except the type of intumescent coatings. The first intumescent coating which is Product A complies with BS 476-20,22 and EN 13381-8 and has an  ISO Standards certificate. Product B  complies with ASTM UL-94 and EN 13381-8 and has a TSE certificate. 12 thermocouples were applied on each steel beam before the intumescent coatings were performed to get temperature-time curves to determine the time to reach the critical temperatures of steel beams which were isolated. Fin EC software was used for the preliminary analysis to determine the critical temperatures and ABAQUS software was used to define the critical temperatures of each insulated steel beam and heat transfer analysis to compare the temperature-time curves with experimental ones to have a better understanding of intumescent coating’s thermal barrier duty in a case of ISO 834 fire type. 

Bio:

Serkan Kocapınar graduated from the Mechanical Engineering Department of Boğaziçi University in 2015. He also graduated from the Civil Engineering Department of Özyeğin University in 2019 as a second major field. In September 2019, he entered the Graduate School of Engineering at Özyeğin University to pursue his MS Degree in Civil Engineering under the supervision of Prof. Gülay Altay and started his teaching assistant duty meanwhile. His research interests cover fire safety of steel structures and structural health monitoring. In this thesis study, he concentrated on the efficiencies of different intumescent coatings for structural steel elements against ISO 834 fire.
