摘要： 本文根据两组翼缘宽比梁高为1的工字形和T形截面部分预应力混凝土梁的试验结果,分析了非预应力钢筋采用Ⅲ级钢筋的可能性;非预应力钢筋中应力变化特点;翼缘剪力滞后影响;不同截面形式对名义拉应力的影响;裂缝计算等问题。并提出有关建议。
关键词: 部分预应力, 应力, 应变, 非预应力钢筋, 名义拉应力, 剪力滞后
Abstract: This paper discusses the test results of two groups of partially prestressed concrete Ⅰ and T beams, with the flange depth ratio of one,and analyses the feasibility of using class Ⅲ steel bars for non-prestressed reinforcement, the non-prestressed steel stress variation along the span, the shear lag in the beam flange, the effect of section type on the hypothetical tensile stresses, crack computation, etc.
Key words: partially prestressed, stress, strain, non-prestressed steel bar, hypothetical tensile stress, shear lag
