摘要:
对不同配筋率的冷轧带肋钢筋混凝土简支标准梁(550 mm×150 mm×150 mm)进行了等幅疲劳荷载试验研究,疲劳试验试件60根,试件配筋率分别为0%,0.29%,0.487%,0.934%和1.946%.这批试件的疲劳破坏形式为:折断破坏、弯拉破坏和剪压破坏.针对不同的疲劳破坏形式,分析了产生不同破坏形式的原因,提出了界限配筋率的概念.受弯构件适当配置冷轧带肋钢筋不仅具有良好的抗裂性能和延性,而且其疲劳寿命也有显著的提高.提出了考虑不同配筋率影响的、可供配筋混凝土路面设计参考的疲劳方程.
Abstract:
Experiment of 60 simply supported concrete beams loaded by equal amplitude fatigue loading was studied. These beams were reinforced by cold-rolled deformed steel bar and were with different reinforcement ratio of 0%, 0.29%, 0.487%, 0.934% and 1.946%. The fatigue failure types of the beams were fracture failure, bending-tensile failure and shear-compression failure. Aimed at the different fatigue failure types of the beams, the failure causes are analyzed. A concept of critical reinforcement ratio is offered. The concrete beams reinforced by adequate cold-rolled deformed steel bar have well resisting-crack ability and ductility, and their fatigue lives increase remarkably. A fatigue equation taken different reinforcement ratio into account is presented, which can be used for design of reinforced concrete pavement.
