Abstract:For the problem of the wind load acting on structure,the current codes and calculation methods can accurately estimate the direct force of wind,but they may neglect the indirect force and make the estimation inadequate.Taking the two-dimensional typical floating structure as the research object,we apply the physical model test to analyze the wind load of constant wind and random wind of two different types of spectrum under hydrostatic condition.The results show that the action force produced by API spectrum random wind is greater than that generated by Davenport spectrum random wind.The average wind speed of different time intervals has great impact on the load of the floating body,so it should arouse the great attention of engineering designers.
