Serviceability of Reinforced Concrete Beams

Serviceability of Reinforced Concrete Beams

Safety and Serviceability of Reinforced Concrete Beam ...

Jul 07, 2016  The safety and serviceability concerns were also addressed by the field monitoring of beam deflections and the strain of the longitudinal rebar in the beams. The maximum beam deflection was only L / 5,000, and the maximum rebar strain was only 3.6% of the yield strain. Field monitoring of the construction load showed that the load on the shores ...

Serviceability Reliability of Reinforced Concrete Beams ...

Mar 27, 2007  To date, attention of researchers concentrated mainly on the serviceability failure of corroded reinforced concrete (RC) beams caused by excessive cracking. However, cracking of the concrete cover and a reduction in the bond strength (which may result in slip between the corroding reinforcement and the concrete) also decrease the stiffness of ...

With the same total reinforcement amount of GFRP and steel bars, the ultimate flexural capacity of GFRP-steel reinforced concrete beams was nearly 91–97% of that of steel-reinforced concrete beams, but the deflection and maximum crack width were obviously larger than those of steel-reinforced concrete beams under the same service load levels.
