摘要
采用经试验结果验证的有限元模型,对影响组合梁抗火性能的混凝土板、钢梁、栓钉相关参数,混凝土板中的纵筋参数,钢梁防火保护层相关参数和荷载参数进行分析研究,得出了对组合梁抗火设计有益的结论。
Parametric studies on fire-resistance of steel-concrete composite beams are conducted using experimentally- verified FEM. The effects of the concrete slab, the steel beam, studs, longitudinal reinforcements in the concrete slab, fire-insulation of the steel beam and load-ratio are investigated. Conclusions are summarized through these studies, which are useful for the fire-resistant design of composite beams.
