Abstract: Using the experimental data of our 50 T-Beams and the material obtained from other countries, this paper analysed the formulas about shear strength in inclined section of reinforced concrete beams for the Current Highway Bridge Code for Design in China.Then we obtained the statistical parameter and probabi listic distribution of the calculation model indeterminateness in shear strength of inclined section for simply supported reinforced concrete T-beams.

Key words: reinforced concerte T-beams, shear strength, calculation model, statistical parameter, probabilistic distribution

摘要： 本文通过50根T形截面梁的试验和收集到的部分国外试验资料,对现行《桥规》中关于受弯构件斜截面抗剪强度的计算公式进行了分析比较,从而得出了关于钢筋混凝土T形截面简支梁斜截面抗剪强度计算模式不定性的统计参数和概率分布。
