| 摘 要： | 分别对内嵌CFRP板、内嵌CFRP筋、内嵌BFRP筋加固钢筋混凝土梁,以及未加固梁进行静力受弯试验,并对试件承载力、荷载-应变曲线以及试件的裂缝形态进行分析。试验结果表明:内嵌CFRP板比内嵌CFRP筋以及内嵌BFRP筋可以更好地提高梁的抗弯承载力;内嵌CFRP板、内嵌CFRP筋以及内嵌BFRP筋都可以较好的约束裂缝的开展。

Experimental investigation of flexural behavior of the RC beams strengthened with different near-surface mounted materials |
| |
| Abstract: | RC beams strengthened with near-surface mounted CFRP plate,CFRP tendon or BFRP tendon,and no-strengthened RC beams were tested under static bends load.The bearing capacity,load-strain curve and fracture shape of specimens were analyzed.Results show that the beam strengthened with near-surface mounted CFRP plate can better improve the flexural capacity than that strengthened with CFRP tendon and BFRP tendon.The near-surface mounted strengthening materials could inhibit the growth of cracks. |
