摘要
采用数值模拟方法,利用有限元软件ANSYS计算分析了无保护层的3层3跨钢管混凝土柱—钢梁平面框架在局部受火条件下的抗火性能,运用顺序耦合方法对结构进行了热—结构耦合分析,得到了结构的耐火极限、临界温度及破坏形态。
The paper adopts the numeric simulation methods, analyzes the fire-resistance performance of the unprotected three-floor and triple span steel pipe concrete column-steel beam plane frame by using the finite element software ANSYS, undertakes the thermal-structural coupling analysis by applying the sequential coupling method, concludes the fire endurance, the critical temperature, and damage forms of the structure.
