The effect of hydrodynamic loads from ocean waves on the strength of horizontal brace structures in semi-submersible platforms was studied. Fifteen different wave loads were considered, including seven used by the classification societies the American Bureau of Shipping and Det Norske Veritas. The results indicate that the torsional moments and shearing forces generated by the waves are the main loads affecting the strength of horizontal brace structures. The eight wave loads not used by the classification societies were found to have a significant effect on the strength of the brace structures and thus need to be considered when designing such structures.

波浪载荷对半潜式平台水平支撑强度的影响

研究了海浪的水动力载荷对半潜式平台水平支撑结构强度的影响。考虑了15种不同的波浪载荷，其中包括美国船级社和Det Norske Veritas船级社使用的7种波浪载荷。结果表明，波浪产生的扭转力矩和剪切力是影响水平支撑结构强度的主要载荷。发现船级社未使用的八种波浪载荷对支撑结构的强度有重大影响，因此在设计此类结构时需要考虑这些因素。
