【摘要】 介绍了基于最优设防烈度的抗震结构优化设计的理论和方法 ,并以渤海油田BZ2 8- 1储油平台为例 ,在目标函数中既考虑了结构的造价又考虑了损失期望 ,根据“小震不坏、中震可修、大震不倒”三个水准的抗震设防原则 ,利用抗震规范的“二阶段”抗震设计方法 ,对其进行了结构优化设计 ,得到了考虑造价和损失期望、基于最优设防烈度的最优设计方案更多还原

【Abstract】 The earthquake resistant design of jacket platform based on optimal fortification intensity is discussed with Platform BZ28-1 of Bohai Oil Field in China taken as an example, following the principle of three level fortification and two stage aseismic design of buildings and both cost and loss expectations taken into consideration.更多还原
