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...
