Study Notes

Function of Structural Elements and Fire Impact

Steel columns provide essential vertical support and stability in building structures.
The effectiveness of steel columns during fire depends on whether they are protected or unprotected.

Protected Steel Columns

Protected steel columns are treated with fire-resistant materials to enhance their capacity to withstand heat during a fire.
Purpose of protection: To delay heating and preserve load-bearing capacity amidst fire exposure.
Common fire protection methods include:
- Application of intumescent coatings that expand when exposed to heat, forming an insulating barrier.
- Encasement in fire-resistant materials, such as concrete, to shield the steel from direct heat.
