Experimental study on the fire resistance of assembled steel structure columns protected by light fireproof materials

Abstract

Abstract: In order to study the fire resistance of prefabricated steel columns，the fire resistance tests of steel columns with different wall thickness under different fire protection methods, different load ratios, axial or eccentric forces were designed. The experimental phenomena and failure patterns of steel columns in assembly buildings under fire protection are analyzed.The influence of steel column wall thickness on temperature rise, fire protection on fire resistance limit, deformation curve of steel column and fire resistance limit were discussed. The suggestions on fire protection of assembled steel structures are put forward.

Key words: assembled steel, columns, fire resistance, fire protection, fireproof materials
