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