Abstract: 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.
