摘要:
以11片碳纤维板加固梁模型为基础,分析了在改变碳纤维板黏贴方式、混凝土强度以及构件剪跨比等因素的条件下梁的应力-应变规律,研究了碳纤维板对梁抗弯承载力的影响。试验结果表明碳纤维板对不同加固方案梁的承载力影响程度各不相同:梁端部有良好锚固措施时,其极限承载力显著提高; 端部没有锚固措施时,其极限承载力主要与碳纤维板锚固长度有关,锚固长度越长,试件极限承载力提高也越显著; 剪跨比相对较大和配筋率相对较小的加固梁极限承载力提高幅度更加显著。
Abstract:
Based on the experiment of 11 models of RC beams with CFRP plates, the regularity of stress and strain of beams with different paste formats, concrete intensity and shear-span ratio were studied, andflexural capacities of beams strengthened with CFRP plates were investigated. The experimental results show that ultimate bearing capacities of specimens vary with different strengthened methods: ultimate bearing capacities of RC beams with CFRP plates end anchorage have been strengthened remarkably; the beams have greater capacity with more anchorage length for those without anchorage; ultimate bearing capacities enhance more prominent for those specimens which have high shear-span ratio and low ratio of reinforcement.
