摘　　要：体外预应力混凝土结构的受弯承载力同多种因素有关,目前还没有较好的计算方法。本文在14根体外预应力混凝土梁模型试验研究基础上,对影响受弯承载力的主要因素进行了分析,并通过对国内外主要规范的比较研究,提出了具有较高精度的体外预应力梁受弯承载力计算公式。The flexural capacity of the external prestressing concrete structure is correlated with a variety of factors,therefore a better method to calculate it is yet to be studied.In an attempt to carry the study further,a test of 14 external prestressing concrete beams was carried out.Through studying the main factors of this experiment,and comparing several formula in different codes at home and abroad,a more accurate flexural capacity formula of external prestressing concrete was presented.

关 键 词：体外预应力混凝土梁 极限应力 受弯承载力
