摘　　要：利用SAFIR有限元分析软件对火灾下钢筋混凝土柱的温度场进行分析和计算,探讨高温下保护层厚度、截面周长、受火时间和截面配筋率对柱截面温度场的分布规律,为进一步认识钢筋混凝土柱的高温力学性能创造条件,并为开展火灾后钢筋混凝土柱的修复加固提供理论依据。The software of SAFIR finite element analysis is used to analyze and calculate temperature distribution of R.C column under fire.This paper explores the distribution from protective layer thickness under high temperature,cross section perimeter,period of fire resistance and reinforcement ratio on column section temperature field.It creates conditions for further understanding of R.C column＇s high temperature mechanical properties and provides the theoretical basis for repairing and reinforcing the R.C column after fire.
