| 摘 要： | 自然环境下通过对配筋混凝土的收缩徐变试验,得出配筋混凝土的收缩徐变远小于现行桥规JTGD62-2004取值,配筋能有效地减小收缩徐变,使用试验曲线更能反映实际工程所用混凝土的收缩和徐变状况。随混凝土的应力水平的增加,徐变系数试验值也略有增加,对于截面应力差较大的结构构件,应力水平不同造成徐变的差异不可忽视。

| Abstract: | From the experiments on creep and shrinkage of reinforced concrete under natural environment,it is obtained that creep and shrinkage values of reinforced concrete are less than the bridge code value in using.The steel bars can effectively decrease creep and shrinkage value.The experimental curve can accurately reflect creep and shrinkage of the actual construction concrete.Along with the increase of stress levels of concrete,the test values of creep coefficient also increased slightly.The different creep co... |
