The corrosion of rebars in reinforced concrete structures cracks the concrete, which leads to degradation bond strength between rebar and concrete. Since deterioration can menace structural safety, evaluation is essential for proper maintenance. In this study, authors investigated by conducting pull-out tests on specimens, with induced crack width stirrups ratio being principal parameters. An e...

In order to improve the failure state of over-reinforced beams and enhance their ductility, an innovative reinforcement method was proposed by adding ultrahigh performance concrete (UHPC) layer on top surface beam take advantage high compressive strength UHPC. The numerical simulation used carry out research. validity finite element model verified comparing it with experimental results, effecti...

carpal fracture-dislocation is regarded as an unusual orthopedic injury and, thus, orthopedic surgeons are less experienced in dealing with and treating these fractures and dislocations. we report a 20-year-old worker man suffering from an unusual carpal fracture-dislocation. there was trans-scaphoid fracture and lunate dislocation with other carpal proximal bones toward volar of the wrist. two...

Evaluating present condition of reinforced concrete (RC) structures is necessary for planning future maintenance and estimating residual service life of structures. A ten point (0-9) condition rating system is proposed for obtaining present condition of RC structures based on the measured values of concrete cover, carbonation depth and chloride concentration at rebar depth through in-situ tests...
