1.
A rational method of optimum design of disaster resistant structures should have following characteristics: multi - stage optimization, consideration of both the cost and the loss expectation of the structure in the objective function, multi - failure criteria for the structure, practical to use and consistent with the National Design Codes.
讨论了抗灾结构优化设计应该具备的一些特点：抗灾优化的层次性；优化的目标必须既考虑结构的近期投资（造价）又考虑其长远效益（遇灾损失期望）；抗灾结构的多级设防原则；最优设防水平的决策；优化方法必须与现行国家设计规范相接轨。
2.
The earthquake-resistant design of jacket platform based on optimal fortification intensity is dis- cussed 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 in- to consideration.
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 BZ28-1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。
3.
In consideration of cost and whole life loss expectation of product, the whole life optimization design model with control parameter of dynamic reliability is proposed.
在同时考虑产品成本价值和全寿命期失效损失期望前提下 ,提出了以动态可靠度为控制参数的全寿命优化设计模型。
补充资料：失望
因希望不能实现而失去信心或感觉不快活：看榜以后，失望而归｜想看电影而看不到，真失望。
