【摘要】 固定式海洋平台地震荷载的大小除了与地震强度相关外,还与平台自身结构特性相关。为了使平台的设计更加合理,对影响地震荷载的相关参数进行分析,考查平台重量、刚度、计算振形数、阻尼比等参数的取值变化对地震荷载的影响,同时根据工程实际需要,推荐各参数取值的一般作法,可为工程设计人员提供参考。更多还原

【Abstract】 The seismic loads on fixed offshore platforms are related to seismic intensity and structure properties.In order to make the design of platforms more rational,this paper studies the effects of seismic load acting on fixed offshore platforms due to the variety of parameters such as mass,stiffness,shape mode number,damping ratio according to analyzing these parameters and recommends the general practice due to engineering project needs.It can provide a design method to designers for reference.更多还原
