Analysis of the Structure Style Selection for Ocean Engineering Floating Structure
Use finite element analysis software ABAQUS to analyze the bearing capacity, strength and wave attenuation performance of very large ocean engineering floating structure based on spatial grid structure, and analyze selected ocean engineering floating structures with different geometrical dimensions. The ocean engineering floating grid structure attenuates wave effectively, whose bearing capacity and strength are high. In the static loads and wave forces analysis, with the dip angle α of belly poles increasing, the maximum stresses decrease, and the bearing capacity lowers; with the height h of the pyramid larger, the maximum stresses and the bearing capacity increase; with the od D of the poles and sphere joints subjoining, the maximum stresses change in concave shape in the whole, and the bearing capacity increases in turn; with the wall thickness t1 of the poles increasing, the maximum stresses under static loads become smaller, but under wave forces the maximum stresses change in concave shape, the bearing capacity declines. The bearing capacity, strength and wave attenuation performance of the structure are influenced by it’s geometrical dimension regularly, and so will affect the project implementation in a practical way.
