In the development of building construction, the use of Structural Steels is now widely used due to itsadvantages in terms of mechanical strength, elasticity, standardization of sizes, ease of fabrication and economic considerations. However, structures made of steel are susceptible to temperature increases during a fire. Currently, there are several typesof fireproofingcoating forStructural Steels such as intumescent coatings, cementitiouscoating products and etc. This paper will discuss the resistance of Structural Steel in the event of a fire between protected and unprotected Structural Steel in Pamitra Workshop. This research is simulated using Ansys heat transfer analysis software. Based on the simulation results, the unprotected Structural Steel reaches a critical temperature (5500C) within 5-6 minutes and has a risk of collapse, then the protected Structural Steel with intumescent coating reaches a critical temperature up to 3 hours and 4 hours with cementitious coating product. Furthermore, the isotropic thermal conductivity decreases significantly from unprotected Structural Steel to protected Structural Steel up to 2000C.

Keywords : Structural Steels, Fireproofing Coating, Ansys.
