Abstract：Due to fact the problem of large proportion by weight and low space utilization of offshore steel platform,a new plate frame type steel platform was proposed.The three-dimensional finite element model of plate frame type steel platform was established based on ANSYS finite element software,and the dynamic response law of displacement and acceleration of the platform under wind-wave-current coupling effect are simulated.The results show that the maximum displacement of the top of the structure is observed when the incidence angle of the wave is 90° and the phase angle is 81°.The incident angle of the load has a significant impact on the displacement and acceleration responses of the plate frame type steel platform.When the load direction aligns with the weak axis of the structure,the responses of the displacement and acceleration of the structure increase substantially.The research has certain reference significance for the design and dynamic analysis of plate frame type steel platform.
