摘要
结合UP软件编程实践,本文对后张预应力混凝土结构计算程序中引入优化功能的意义进行了论述,提出了预应力筋与普通钢筋之间的最优搭配关系、优化原点概念及相关影响因素,列出了优化计算程序所应涉及的基本计算内容,并对当前后张预应力混凝土结构设计中的一些观点提出了不同意见。
In this paper, on the basis of the practice of writing UP program, the significance of optimized computing in design of post stressed concrete structures is discussed. The reasonable combination of both post tensioned tendons and steel bars with the concept of optimized origin in design calculation is presented with correlate factors. After spreading out the basic calculating contents in optimized design of post stressed structures by special program, some new design viewpoints are proposed.
