内嵌锚具夹持CFRP板与混凝土锚固性能研究
Research on Anchorage Behavior of CFRP Plates Clamped by Embedded Anchors in Concrete
摘要
Abstract
[Objective]To enhance the bonding performance of near-surface-mounted carbon fiber reinforced polymer(CFRP)plates in concrete,a novel embedded anchorage reinforcement method is proposed.[Methods]Mechanical anchor-age of CFRP plates was achieved by utilizing the clamping force generated by bolt-tightened steel anchorages.Tests were con-ducted to evaluate the clamping force and anchorage force of three types of anchorages with varying diameters under different bolt torque levels.Based on these results,single-lap shear tests were performed on nine bonding specimens with near-surface-mounted CFRP plates and twenty-four anchorage specimens with CFRP plates clamped by embedded anchorages.The failure modes of both types of specimens,the strain distribution in the CFRP plates,and the anchorage force were analyzed.[Results]The anchorage specimens exhibited two failure modes:relative slip between anchorages and plates,and tensile rupture of the CFRP plates.The anchorage force of CFRP plate specimens clamped by the three types of anchorages with dif-ferent diameters was independent of concrete strength and anchorage spacing.Furthermore,specimens with larger diameter anchorages demonstrated higher anchoring capacity,and increasing the number of anchors effectively improved the anchorage force.[Conclusion]The load transfer mechanism between the embedded anchor-clamped CFRP plates and concrete is re-vealed,and the calculation formulas for the anchorage force of various anchors are derived,which provide theoretical support for the design and performance evaluation of members strengthened with CFRP plates clamped by embedded anchors.关键词
