风载荷是一种随机载荷,能够引起焦炭塔的振动。为研究风载荷对焦炭塔强度的影响,利用ABAQUS对焦炭塔进行了风载荷的动态分析,考察了载荷加载过程与卸载之后结构的动态响应。结果表明,在风压作用下,最大节点位移出现在塔体顶部,最大值为0.79 mm,最大应力出现在裙座固支端附近的节点处,最大值为3.26 MPa,不会引起结构的失效；在加载与卸载后的一段时间内,结构沿载荷作用方向产生频率为10 Hz 的振动,在外载作用下容易引起结构的共振,造成结构的破坏失效。因此,在焦炭塔的设计及运行中必须充分考虑。

Wind load is a random load that can lead to the vibration of the coke tower.In order to research the influence on the strength of the coke tower by wind,ABAQUS was used to conduct the dynamic analysis of the wind load and the response of the structure during loading and unloading.The results indicate that,with the effect of wind,the maximal nodal displacement appeared at the top of the tower,which is 0.79 mm;while the maximal stress locate at the node around the skirt,the maximum is 3.26 MPa.Both of the displacement and stress could not cause the failure of the structure.During the loading and unloading,the structure engendered vibration along the loading direction.The vibration frequency was 10 Hz.Under the effect of external loads,it could easily cause the resonance of the structure,which could cause damages to the structure.Therefore it must be taken into consideration during the process of design and operation.
