A study of the wave impact loads on a fixed column-slab combined structure with a GPU-accelerated SPH method

Wave impacts on a semi-submerged platform have a great influence on the structure. Physical experiments and numerical simulations are carried out based on fixed horizontal deck and column-slab combined structures. During the physical experiments, the impact pressures acting on the horizontal decks a...

During the physical experiments, the impact pressures acting on the horizontal decks are measured to verify the accuracy of the numerical models.
