Abstract EN
The offshore structures that play a vital role in oil and gas extraction are always under complicated environmental conditions such as the random wind loads.
The structural dynamic response under the harsh wind is still an important issue for the safety and reliable design of offshore structures.
This study conducts an investigation to analyze the wind-induced structural response of a typical offshore deck structure.
An accurate and efficient mixture simulation method is developed to simulate the fluctuating wind speed, which is then introduced as the boundary condition into numerical wind tunnel tests.
Large eddy simulation (LES) is utilized to obtain the time series of wind pressures on the structural surfaces and to determine the worst working condition.
Finally, the wind-induced structural responses are calculated by ANSYS Parametric Design Language (APDL).
The numerically predicted wind pressures are found to be consistent with the existing experimental data, demonstrating the feasibility of the proposed methods.
The wind-induced displacements have the certain periodicity and change steadily.
The stresses at the top of the derrick and connections between deck and derrick are relatively larger.
These methods as well as the numerical examples are expected to provide references for the wind-resistant design of the offshore structures.
