本文是笔者文献[1]的继续和发展。该文以当前国内外公认比较合理、可行的,国际统一水准2的近似概率法为基础,继续讨论文献[1]的课题,探讨了按随机变量函数的最优设计原则,给出可能约束条件式及目标函数式。参考国内外有关文献资料的统计数据,给定统计值,计算获得最优解,并与文献[1]进行对比和分析。预计到85年,我国将按《建筑结构统一标准》重新颁发荷载和结构设计新规范,故本次研究的课题及方法,不仅在理论上,而且在实践上都可能是一个有意义的尝试。
This article is the continuation and development of the author’s literature [1]. This paper is based on the approximate reasonable probabilistic method that is generally accepted at home and abroad and is relatively reasonable, feasible, and internationally consistent, and continues to discuss the topic of literature [1]. It discusses the optimal design principle based on the function of random variables and gives possible constraints. Formula and objective function. With reference to the statistical data of domestic and foreign relevant literature data, given the statistical value, the optimal solution is calculated and compared with the literature [1]. It is expected that by the year 85, China will re-issue the new norms for load and structural design in accordance with the “Unified Standard for Building Structures”. Therefore, the topics and methods of this study may be a meaningful attempt not only in theory but also in practice.
