本文是为修订《部分预应力混凝土结构设计建议》的背景材料。该建议是由中国土木工程学会混凝土和预应力混凝土学会制订的。文中总结了国际上的研究成果,指出了存在的问题。对屈服转角的计算和影响部分预应力混凝土的因素提出了意见。对今后研究和修订《建议》做了建议。 This article is a background material for the revision of the “Proposal for Design of Partially Prestressed Concrete Structures.” This proposal was formulated by the Society of Concrete and Prestressed Concrete of the Chinese Civil Engineering Society. The paper summed up the international research results and pointed out the existing problems. The opinions on the calculation of the yield angle and the factors that affect the partial prestressed concrete are presented. Suggested future research and revision of the “Proposal.”
