Outline
As a new type of structure, there is no mature design and strength analysis method for large-span reticulated shell structures of offshore tourism platforms. In this paper, the relative vertical displacement of the reticulated shell structure column was taken as the wave load control condition, and the wave load was calculated based on the design wave method and the three-dimensional hydroelastic theory.With the once-in-a-century wind speed taken as the wind load working condition, the turbulence model of k-ε was adopted to simulate the wind field for calculation of the wind load, the panel integration method was used to calculate the equivalent node load of the reticulated shell structure, and the calculation method of the external load for large-span shell structures was thus established. On this basis, taking the“Heart of the Sea”tourism platform as an example, the response analysis of the reticulated shell structure was carried out, and the responses of the reticulated shell structure under the action of wind load, wave load and combined loads of both were obtained. The effects of wind load and wave load on the response of the reticulated shell structure were compared and analyzed.
