We measure the hadronic branching ratios of the Z boson into heavy quarks: Rb = ΓZ0→bb/ΓZ0→hadrons and Rc = ΓZ0→cc/ΓZ0→hadrons using a multi-tag technique. The measurement was performed using about 400,000 hadronic Z events recorded in the SLD experiment at SLAC between 1996 and 1998. The small and stable SLC beam spot and the CCD-based vertex detector were used to reconstruct bottom and charm ...

The use of Fiber Reinforced Polymer (FRP) reinforcement is a practical alternative to conventional steel rebars in concrete structures subjected to aggressive environments. The solution is attractive for bridge deck and rail applications, as it eliminates corrosion of the steel reinforcement, which is the major instrument of degradation. Due to the peculiar physical and mechanical characteristi...

This study aimed to investigate the precast reinforced concrete beam-to-column joints behaviors through replaceable damper under cyclic loading. The specimens have been embedded with steel reinforcement and specially shaped connectors. After application of loading, energy dissipation part has acted very well increased bearing capacity specimens. beam–to–column were designed analyzed compare (RC...

The flexural strengthening of reinforced concrete (RC) beams by bonding external composite materials has proved to be an effective and convenient technique. Several works, focus on mechanical behaviour continuous beam with two spans strengthened materials, were reported in literature. This paper presents the capacity RC three or repaired carbon glass fibre polymer (CFRP GFRP) sheets. Experiment...

Adequate rebar-concrete bonding is crucial to ensure the reliable performance of reinforced concrete (RC) structures. Many factors such as properties, cover depth, transverse reinforcement, and presence corrosion will affect bond behavior, consequently, structural performance. While many prior studies have focused on influence aforementioned strength, impact these failure mode has not been thor...

A new layered 4-node, 24-degrees of freedom rectangular composite plate element is developed in this paper for nonlinear finite element analyses of FRP-strengthened RC slabs. The layered approach is used to form an integrated plate element for modelling of concrete, FRP, adhesive layer and steel reinforcement with a perfect bond assumption between each layer. Timoshenko’s composite beam functio...

The performance of the interface between fiber reinforced polymer (FRP) composites and concrete is one of the key factors affecting the behavior of strengthened reinforced concrete (RC) structures. Existing laboratory research has shown that RC beams strengthened with FRP sheets usually fail because of either debonding of the impregnated fabric from the concrete substrate or fracture of the FRP...

Seismic pressures on a reinforced concrete moment-resisting structure are known to create critical and essential regions at the beam-column joints. Beam-column junctions microcosm of whole structure, therefore brittle behavior these points predicts action. Ductile joints ductile Under influence seismic forces, between RC beams columns exposed high shear stresses. Learn more about performance fi...

BACKGROUND AND PURPOSE Recently, the use of stents to assist in the coiling and repair of wide-neck aneurysms has been shown to be highly effective; however, the effect of these stents on the RC of the parent vessel has not been quantified. The purpose of this study was to quantify the effect of intracranial stenting on the RC of the implanted artery using 3D datasets. MATERIALS AND METHODS T...
