以玄武岩纤维布全包不同尺寸混凝土圆柱轴心受压试验为基础,对玄武岩纤维布加固素混凝土圆柱力学性能及其尺寸效应对加固效果的影响做了研究,并提出玄武岩纤维布约束素混凝土圆柱轴心抗压强度模型.结果表明,该模型与试验得出的数据有良好的吻合度,且不同尺寸的混凝土圆柱存在尺寸效应.
Based on a test of circular concrete columns of different sizes confined by BFRP under uniaxial load, the mechanics properties and size effection of specimens were studied and axial compressing strength model of specimens was presented. The results suggest that the model has a good degree of agreement with experimental datas and circular concrete columns of different sizes exist size effection.
