✦ Synopsis

Flexural behavior of reinforced concrete rectangular beams with epoxy bonded carbon fiber reinforced plastic (CFRP) laminate is experimentally investigated, Comprehensive test data are presented on the effect of CFRP laminates, bonded to the soffit of a beam, on the first crack load, cracking behavior, deflections, serviceability loads, ultimate strength and failure modes. The increase in strength and stiffness provided by the bonded laminates is assessed by varying the number of laminates. The results generally indicate that the flexural strength of strengthened beams is significantly increased. Theoretical analysis using a specially developed computer software is presented to predict the ultimate strength and moment defection behavior of the beams. The comparison of the experimental results with theoretical values is presented, along with an investigation of the failure nodes.

Experiments of four reinforced concrete (RC) two-span T-beams were introduced. During the experiment, one T-beam was normal temperature control T-beam, and the other three T-beams were heated 75 minutes under ISO-834 standard fire (ISO 834, 1975). Among these three T-beams, One T-beam was unstrength

External bonding of fibre reinforced plastic (FRP) strips to reinforced concrete (RC) beams has been widely accepted as an effective method for strengthening. The ultimate flexural strength of strengthened RC beams can be improved significantly, but it is often impaired by premature failure modes, s
