In this study, an experimental program was developed to investigate the flexural behavior of pre-damaged reinforced concrete (RC) beams that had been repaired and strengthened using carbon fiber-reinforced polymer (CFRP) laminates under a monotonic load. Two techniques were used: externally bonded reinforcement (EBR) near-surface-mounted (NSM) reinforcement, repair strengthen tested beams. The ...

The failure of a reinforced concrete (RC) beam–column joint during an earthquake can lead to the progressive collapse entire structure. This type failure, which has been mainly observed among structures built prior 1970s, occurs due poor design and inadequate detailing rebars. Recently, number researchers have conducted numerous experiments improve overall performance joints in terms strength, ...

The ability to predict the resistance of reinforced concrete (RC) structures progressive collapse as a result an interior column removal has become need in structural design. In general, three mechanisms characterize structure collapse, flexural action, compressive arch and tension catenary action. objective this study is investigate effects floor system configurations on collapse-resistance RC...

Non-destructive testing in reinforced concrete (RC) for damage detection is still limited to date. In monitoring the damage in RC, 18 beam specimens with varying water cement ratios and reinforcements were casted and tested using a four-point bending test. Repeated step loads were designed and at each step load acoustic emission (AE) signals were recorded and processed to obtain the acoustic em...
