摘要/Abstract

摘要： 为研究装配式钢结构柱的耐火性能，开展不同壁厚的方钢管柱在不同防火保护方式、不同荷载比、轴心及偏心受力情况下的耐火性能试验，分析了装配钢柱火灾下的试验现象、破坏形态，探讨了钢柱壁厚对升温的影响、防火保护对耐火极限的影响、钢柱变形特点及耐火极限，对装配式钢结构防火保护提出建议。

关键词: 装配式钢柱；耐火性能；防火保护, 防火材料

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
