摘　　要：分析了长扁圆形烟囱宽面迎风时风压和平台荷载对烟囱受力的影响,运用ANSYS和ABAQUS软件进行了仿真计算,计算中考虑了几何非线性的影响,并考虑最不利受力情形,计算了烟囱沿高度方向应力、环向应力、位移,详细比较了两软件计算的竖向拉应力、环向拉应力的变化规律,发现计算结果比较接近,相互验证了计算的正确性.应力计算结果可供长扁圆形烟囱配筋计算时参考.The influence of wind pressure and flat roof load to chimney was analysed. ANSYS and ABAQUS software were used for calculation and simulation. The influence of geometry non-linear and the most disadvantage suffering force were considered. Stress along altitude, ring direction, and displacement of chimney were calculated. Variety rule of vertical pull stress, annular pull stress were analyzed by two softwares and compared. The results were relatively adjacent which verify the correctness of calculaton. The result can be referred in steel calculation of flat circular chimney.
