| 摘 要： | 本文利用斜压场理论,考虑混凝土的“软化”性能,对开裂状态下的予应力混凝土受扭构件进行了全过程分析,并用国内外49个试件的试验结果作了比较。此外,还对我国新修订的混凝土结构设计规范的予应力混凝土受扭构件设计计算方法进行了分析和讨论,并提出了若干建议。

| Abstract: | In this paper, based on the theory of diagonal compressive field and considering the "Softening" process of cracked concrete, a computer analysis is given for the theoretical complete response process of cracked prestressed concrete member under torsion. Satisfactory results have been obtained in our calculation by comparing with measured ones. Moreover, the design method of prestressed concrete member under torsion recommended in the new Chinese Building Code is discussed and some rational proposals are given. |
