To accurately evaluate the overall corrosion degree of reinforced concrete (RC) beams, on basis SMFL technology, random detection experiment six RC beams was carried out. The relationship between tangential component By and normal Bz magnetic induction intensity analyzed, a multidefect dipole model established. correlation average ratio C beam characteristic index KG emphatically explored. resu...

The near-surface-mounted (NSM) fiber-reinforced polymer (FRP) strengthening technique for reinforced-concrete (RC) beams has attracted worldwide research attention and application in the past two decades. In spite of improved bond strength between NSM FRP concrete, compared with externally bonded (EB) method, premature debonding failure still occurs, and, hence, efficiency intervention is limit...

A total of nine specimens were constructed and tested under cyclic loads to investigate the differences in seismic behavior between glass fiber-reinforced polymer (GFRP)-reinforced concrete (RC) joints RC beam-to-column joints. The experimental parameters included stirrup ratios, axial pressure ratios strength loading test results showed that GFRP-RC can withstand significantly high lateral def...

Reinforced concrete (RC) frames subjected to seismic loading often depict localized member-end deformations due to strain penetration effects between adjacent members, such as beam-column and column-footing joints. Past experimental programs indicate that the bond-slip deformations occurring at the interface between the reinforcement and the surrounding concrete can contribute up to 40% of the ...

Various types of shear reinforcement are used for example general closed stirrup and bar with mechanical anchor. However, most standards specifications take only the cross-sectional area vertical components into account when determining their effect, such as on crack development strength. Consequently, full effect different shapes failure behavior reinforced concrete (RC) beams is not clear. In...

introduction: an overlooked but important part of successful root canal treatment is a straight-line access (sla). the purpose of this in vitro study was to compare the efficacy of introfile and prerace rotary instruments with gates glidden (gg) drills in gaining sla by cone-beam computed tomography (cbct). methods and materials: a total of forty five extracted mandibular first molars were sele...

The existing literature mainly focuses on the research of reinforced concrete (RC) beams under a single load such as blast or impact. In this paper, slab–rib–slab RC beam, new type structure widely used in bridge structures, was taken object. explicit dynamic analysis software LS-DYNA to numerically analyze response and failure behavior I-shaped combined impact loads. For reason, an effective n...

To improve the ductility and seismic performance of a double coupling beam, authors applied polyethylene terephthalate (PET) sheet steel tube to form fiber-reinforced polymer (FRP)–concrete–steel double-skin tubular (DST) composite beams. A low-cyclic reversed experimental program was carried out which factored in member form, diameter, construction methods. The results indicate that energy dis...

External beam radiotherapy to the pelvis is related with the development of radiation colitis, a consequence of radiationinduced mucosal and bowel wall injury. Although in recent years radiation techniques have improved, radiation toxicity remains a significant clinical problem resulting in treatment delays, increased patient hospitalization rates and remarkable shortand long-term morbidity [1]...
