摘要
采用有限元和数值积分方法对内 (圆 )钢管增强方钢管混凝土柱在火灾下的温度场和耐火极限进行了分析和计算 ,讨论了各类参数对高温下内 (圆 )钢管增强方钢管混凝土柱的耐火性能的影响 ,并对其工程应用进行了展望。表明内 (圆 )钢管增强方钢管混凝土柱的耐火性能是明显的。
Using the method of the finite element and numerical integration, the temperature field and fire resisting limit of concrete\|filled square steel tubular columns reinforced by the inner circular steel tube are analyzed and calculated.Effects of parameters on the fire resisting performance of the columns under high temperature are discussed, and the outlook of engineering application of the columns is also given. Results show that the fire resisting performance of the columns is efficient.
