碳纤维加固与钢板加固混凝土梁抗震性能对比

Carbon fiber reinforced concrete beams is compared with the seismic performance of steel reinforced concrete beam

通过对地震损伤钢筋混凝土梁加固修复方法的研究,进行了不同配筋率的梁在水平低周反复荷载作用下的试验。对损伤后的梁进行了加固修复,并对加固修复梁在再次地震作用下的抗震性能进行了试验。主要研究内容:完成了6根试验梁的制作,并对其在位移控制下进行了水平低周反复荷载试验,重点研究了不同配筋率的钢筋混凝土梁碳纤维加固与钢板加固的抗震性能分析比较。

The experiments on seismic damage reinforced concrete beam reinforcement repair methods are studied in this article. The variable major test are reinforcement ratio and axial compression ratio. RC beams with different reinforcement ratio under low cyclic loading are experimented. The beams are strengthened and repaired using car- bon fiber sheet and steel plate after injured, and experimented under low cyclic loading. The following aspects are carried out： Six beams are made and tested under low cyclic loading. The seismic behavior of RC beams with differ- ent reinforcement ratio with different axial compression ratio is evaluated.
