Civil infrastructure especially the rigid pavements have been increasingly covering a huge part of the infrastructure around us with the demand of rapid urbanization. The quality and condition assessment of it after its construction is an important issue with the engineers. The need for defect diagnosis and verification of their various design parameters is vital and important for quality contr...

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...

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...
