Abstract :
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.
