As a novel civil engineering material, Engineered Cementitious Composite (ECC) has attracted more and attention due to its strain-hardening characteristics, good post-cracking resistance unique properties. Bonding between rebar great effect on the mechanical behavior of structural members. In this paper, direct pull-out tests were conducted understand bond ECC rebar. The test parameters include...

Fiber reinforced Composite (FRC) retainers have been introduced as an aesthetic alternative to conventional metallic splints, but present high rigidity. The purpose of the present investigation was to evaluate bending and fracture loads of FRC splints bonded with conventional full-coverage of the FRC with a composite compared with an experimental bonding technique with a partial (spot-) resin c...

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...

A search of the Cambridge Structural Database (CSD) was carried out for phosphine-water and arsine-water complexes in which water is either the proton donor in hydrogen-bonded complexes, or the electron-pair donor in pnicogen-bonded complexes. The range of experimental P-O distances in the phosphine complexes is consistent with the results of ab initio MP2/aug’-cc-pVTZ calculations carried out ...

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...
