摘要

碳纤维布或钢板加固混凝土构件在改善结构抗震性能上均存在不足，二者复合加固具有互补性。基于此，对6根钢筋混凝土梁(5根梁加固）在低周反复荷载作用下的抗震性能进行对比试验，对其破坏特征、滞回曲线、位移延性系数、骨架曲线、刚度退化、承载能力进行对比分析。试验结果表明：复合加固更有效地提高梁的承载力、延性和变形能力，减缓刚度退化，改善钢筋混凝土梁的抗震性能，碳纤维布与钢板能较好地协同工作。

Abstract

Neither the Carbon Fiber Reinforced Plastic nor the steel plate strengthening concrete components shows sufficiency in improving the structures' seismic behaviors independently

while they complement each other by the way of composite strengthening. Six reinforced concrete beams

five of which are strengthened

were comparatively and experimentally tested under low frequency cyclic load to investigate their mechanical performances such as characteristic of resilience

hysteretic curve

seismic behaviors

skeleton curve

degeneration of rigidity and loading capacity. It is indicated that the way of composite strengthening can boost the beams′ ultimate bearing capacity

ductility and deformability capacity effectively

and it can delay rigidity degeneration and improve the seismic behaviors of the beams. Also

the CFRP and steel plate can work together very well.
