| 摘 要： | 本文通过对17块钢筋砼平板进行的试验,研究了开裂砼的软化性能。 研究表明:与单轴受压圆柱体试验结果比较,开裂砼不仅存在强度的降低,而且还出现峰值应变的提高。通过分析,文中提出了以“砼本软化构有效主拉应变”表述的关系公式。

| Abstract: | Seventeen reinforced concrete panels have been tested in order to study the softening properties of cracked concrete.The test results show that the cracked concrete presents not only the phenomenon of reduction in strength, bus also the phenomenon of increase in peak strain as compared to the test results of a cylinder subjected to uniaxial compression.As a result of analysis, a constitutional relationship of softened concrete has been established and expressed in terms of the "effective principal tensile strain". |
