Long‐Term Deflection of RC Beams

Journal of Structural Engineering, 1994
Long‐term deflection of statically determinate reinforced concrete beams under service loads is analytically studied. The BP‐2 creep and shrinkage model is adopted and extended to accommodate concrete tensile behavior by assuming a tensile stress‐strain relation.

An experimental approach for shear strengthening of RC beams using a proposed technique by embedded through-section FRP sheets

, 2020
This article presents a new technique for enhancing the shear capacity of RC beams with FRP materials, which instead of bonding of FRP strips on the external face of element, involves perforating holes along the beam web, inserting FRP reinforcement ...

Shear strength of plated RC beams

Magazine of Concrete Research, 1995
Use of externally bonded plates to strengthen or repair damaged reinforced concrete (RC) beams and slabs has gained universal acceptance. However, questions remain regarding the possibility of a highly brittle mode of failure, referred to in the literature as shear failure for certain combinations of plate geometry and other parameters.

A Beam Finite Element for Shear-Critical RC Beams

SP-237: Finite Element Analysis of Reinforced Concrete Structures, 2006
The proposed beam finite element is capable of describing the response of reinforced concrete members under the interaction of axial force, shear, and bending moment. The element is based on a mixed formulation and does not exhibit the shear locking problems of displacement-based elements.

Size effect in shear failure of RC beams with stirrups: Simulation and formulation

Engineering structures, 2019
The objectives of the present study are to discover the influences of stirrup ratio and shear-span ratio on the shear failure and size effect of reinforced concrete (RC) beams having different sizes, and to build a theoretical formula for quantitatively ...

Required plastic rotation of RC beams

Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2006
Linear analysis with moment redistribution has been allowed under codes of concrete structures for a long time. There is, however, still a certain lack of consensus regarding the value of the redistribution coefficients. The calculation of those coefficients ignores the influence of some factors in moment redistribution, and this may lead to designs ...
