摘　　要：从防火设计的角度,分别选用欧洲规范3:钢结构设计(EC3)和GB 51249—2017《建筑钢结构防火技术规范》标准计算火灾中门刚结构内力和位移,并通过变换荷载的方向(竖向荷载变为风荷载),分析不同荷载组合方式下,运用EC3和GB51249—2017规范计算差异,得出结论,供设计人员借鉴。From the perspective of fire resistant design,EC3 and GB 51249—2017 standards are selected to calculate the internal force and displacement of portal frame structure in fire,and by changing the direction of load(vertical load becomes wind load),the calculation difference of EC3 and GB 51249—2017 standards under different load combinations is analyzed,and the conclusions are drawn,which can be used for reference by designers.
