摘要: Fiber reinforced polymer (FRP) materials are currently produced in different configurations and widely used for the strengthening retrofitting of concrete structures bridges. Recently, considerable research has been directed to characterize use FRP bars strips as near surface mounted reinforcement, primarily applications. Nevertheless, in-depth understanding bond mechanism is still a challenging issue. This paper presents both experimental analytical investigations undertaken evaluate characteristics carbon (CFRP) strips. A total nine beams, strengthened with CFRP were constructed tested under monotonic static loading. Different embedment lengths development length needed effective closed-form solution proposed predict interfacial shear stresses. The model validated by comparing t...
