本文汇总了作者在两期论文集中发表的关于部分预应力混凝土的论述,收集了该领域中的最新研究成果,并对部分预应力混凝土的分析与设计提出了综合性的评述,重点是美国的进展。本文在统一现有计算方法和反映最新发展的建议方面进行了专门的探讨,并阐述了在静载和疲劳荷载作用下部分预应力混凝土梁的强度和延性性能的一些研究成果。
This paper summarizes the author’s expositions on partially prestressed concrete published in two papers and collects the latest research results in this field and presents a comprehensive review on the analysis and design of some prestressed concrete. progress. In this paper, special discussions are made on the harmonization of existing calculation methods and the suggestions on the latest development. Some results of research on the strength and ductility of partially prestressed concrete beams under static and fatigue loads are also presented.
