Response analysis of large container ship bridge wing structures under dynamic wind loads

Objectives  The aim of this paper is to study the influence of wind load on the safety of the bridge wing structure of a large container ship.

Methods The variation patterns of dynamic wind load at different vertical positions are investigated and a method is proposed that applies dynamic nonlinear wind load. ABAQUS software is used to solve the nonlinear finite element model of the bridge wing structure and obtain the stress and deformation results of the structure under dynamic wind load. The synergistic effects of multiple loads on the structural response are then obtained and compared with the results of static wind load structural strength calculations in order to explore the impact of dynamic wind load effects on the response of upper building structures.

Results The results indicate that the dynamic effects of wind load significantly affect the bridge wing structure, causing periodic oscillations of the bridge wing and leading to significant structural periodic responses under the combined action of multiple loads.

Conclusions The findings of this study can provide important references for further understanding and considering the role of wind load in structural design.
