局部配CFRP-PCPs复合筋混凝土梁受力性能试验

摘要

In this paper,the mechanical behavior of concrete beam which is reinforced by CFRP-PCPs within the range of two meters of the compression zone in the mid-span is studied.Based on the test values of the specimens,the detail studies on flexural behavior and failure modes are conducted.Through the reorganization and induction of the experiment data,the influence of sectional dimensions and quantity of the CFRP-PCPs and the prestressed of CFRP on the flexural performance are discussed.Experiments show that partial reinforced concrete beam with CFRP-PCPs reinforcement shows good mechanical performance,and the CFRP-PCPs can play a good performance when reinforced in the beams.%针对局部(跨中受拉区2m范围内)配碳纤维增强塑料预应力混凝土棱柱体(CFRP-PCPs)复合筋的钢筋混凝土梁进行受力性能试验.分析了局部配CFRP-PCPs复合筋梁的受力过程、破坏模式,对试验数据进行了整理和归纳分析,探讨了不同复合筋数量和截面大小、CFRP筋预应力大小对局部配CFRP-PCPs梁的抗弯性能的影响.研究表明:局部配CFRP-PCPs复合筋梁表现出良好的受力性能;局部配置时,CFRP-PCPs复合筋的性能都能发挥良好.
