【摘要】 进行了5根钢筋混凝土梁的试验,通过这些粘贴CFRP、GFRP及CFRP/GFRP混杂加固钢筋混凝土梁在不同加载历程下的对比试验,研究了不同初始应力状态下FRP加固钢筋混凝土梁的破坏模式、抗弯正截面承载力、弯曲变形,混凝土、钢筋和纤维布的应变以及裂缝开展等方面的内容.更多还原

【Abstract】 In this paper, five R.C beams strengthened with CFRP, GFRP, CFRP/GFRP laminates have been performed on different stress level. Destroy patterns, flexural capacity, flexural deformation, strain, crack developing of R.C beams strengthened with FRP laminates have been studied.更多还原
