Analys and economic comparison of steel columns design in fire conditions

Abstract

Load-bearing structures must provide both safety and economic efficiency. Steel columns are being optimized for fire-resistance due to rising material costs. STN EN 1993-1-2 standard provides guidelines for designing fire resistant structures and determining the appropriate protection measures. Fire protection methods include sprays, coatings, and claddings. This study analyses and compares various design approaches for steel columns in fire conditions, emphasizing economic efficiency.
