摘要
开展了系列尺寸再生混凝土无腹筋梁抗剪性能试验研究,考察了在梁的剪跨比保持不变的条件下,梁的开裂荷载、剪应变、剪切裂缝强度、极限承载力和抗剪强度等参数随梁的尺寸改变而变化的规律,比较全面的研究了再生混凝土梁抗剪性能方面的尺寸效应规律。试验结果表明:再生混凝土无腹筋梁的剪切裂缝强度、最大剪应力和抗剪强度均存在着明显的尺寸效应。
Recycled concrete beams without web reinforcement subjected to static loading were tested to study their shear performance.The effects of beam length and cross section height on the shear performance were investigated.The experimental results show that theshear performance of recycled concrete beams has a significant size effect.
