摘要
本文以导管架平台为对象,首先通过计算导管架平台构件上的外荷载,将组成平台的每一根杆件所受波浪力和海流力等外荷载计算得出,然后将这些外载荷施加到以平台为整体的结构物杆件上,利用结构有限元软件分析导管架平台在波浪和海流作用下的结构内力响应。本文所提出的方法可为导管架平台在海洋环境下构件内外力载荷分析以及在这些载荷作用下平台的动力响应特性评估提供手段。
A jacket platform is taken as the research object. The hydrodynamic loadings due to wave and current on the members of the platform are first calculated, these loadings are then exerted on the every members of the platform by applying commercial finite element software to analyze the structure internal force responses under these hydrodynamic loadings. The approach proposed in this paper provide a means to analyze the hydrodynamic and structural responses of the platform in ocean environment and a way to evaluate the dynamic characteristics of the platform under these loadings.
