摘要
通过16个体外缠绕不同间距细钢丝绳的混凝土圆柱体试件的轴心受压试验,研究了该类约束混凝土的受力特性。结果表明,体外绕丝约束混凝土的抗压强度和延性有很大程度的提高和改善,有望在钢筋混凝土受压构件加固中应用。
Experiments were done on 16 circular concrete short columns wound with thin steel cable in different interval. The forced characteristics of this type of confined concrete under axial compression is rsearched. The result indicates that the compressive strength and ductility of the columns are improved efficiently by the external confining steel cable.
