重复荷载下钢筋混凝土柱轴压性能的尺寸效应试验研究
|
摘要
为了解重复荷载下钢筋混凝土柱轴心受压性能的尺寸效应,按照相似关系设计了3组正方形截面钢筋混凝土柱试件,其几何尺寸分别为:400mm×400mm×1 200mm、600mm×600mm×1 800mm、800mm×800mm×2 400mm,并对其进行了轴压破坏试验。试验中对比分析了各试件的破坏特征、裂缝发展过程、承载力、峰值应力、峰值应变以及刚度等。结果表明,在试验的尺寸范围内,试件的轴压性能存在明显的尺寸效应。
The size effects on axial compression performances of reinforced concrete column under repeated load are needed.Specimens were designed and tested in accordance with the relevant similarity,whose geometric dimensions are: 400 mm×400 mm×1 200 mm,600 mm×600 mm×1 800 mm and 800 mm×800 mm×2 400 mm.The result of the experiment,the failure characteristics,crack development process,strength,peak stress,peak strain and stiffness of various specimens were comparatively analyzed.The results show that,within size range of this test,size effect exists on performances of columns.
