摘要
进行了5根碳纤维布加固高强钢筋混凝土梁抗弯性能的试验,其中3根为预裂梁,2根为对比梁,分析了不同损伤程度对加固效果的影响。试验结果表明,在一定范围内,损伤程度对加固梁的极限荷载影响不大,对梁的抗弯刚度影响较多。
Based on the test of five high-strength reinforced concrete beams strengthened with externally bonded carbon fiber reinforced sheets which includes three precracked beams and two reference beams, the influence of damaged degree were studied and analyzed, It is shown that deferent damaged degree shows similar limit loads, but deferent section stiffness.
