Repaired Reinforced Concrete Beams

ACI Materials Journal, 1990
The repair of cracks is a necessity, and a comparison between repair methods for reinforced concrete beams subjected to different levels of cracking was made experimentally. Four methods of repair were studied: epoxy injection; ferrocement; steel-plate bonding; and combined method of epoxy injection and ferrocement.

Concrete Beams with Prestressed Reinforcement

Journal of the Structural Division, 1970
Tests on six rectangular beams reinforced with variable amounts of deformed steel bars and precast prestressed concrete prisms are reported. Methods are suggested for computing the moment causing cracking of the in situ concrete and that causing cracking of the prestressed reinforcement.

Maximum Shear Reinforcement of Reinforced Concrete Beams

ACI Structural Journal, 2010
The ACI 318-08 Code requires the maximum amount of shear reinforcement in reinforced concrete (RC) beams to prevent possible sudden shear failure due to over reinforcement. The design equations of the maximum amount of shear reinforcement provided by the current four design codes—ACI 318-08, CSA-04, EC2-02, and AIJ-99, differ substantially from one ...

The reinforced concrete beam

1972
Although the geometry of the influence of the load on a beam is identical irrespective of material there is a fundamental difference in the way that a reinforced concrete beam produces the resistance moment. Within very small limits, a plain concrete beam would behave like any other elastic material.

Reinforced concrete repairs in beams

Construction and Building Materials, 1999
Abstract The effectiveness of reinforced concrete repairs may be established in terms of their ability to restore the structural integrity of the reinforced concrete element and to protect the reinforcement from severe weathering conditions. Therefore, 18 large scale reinforced concrete beams were cast and subject to an accelerated corrosion ...

Longitudinally Restrained Reinforced Concrete Beams

Journal of the Structural Division, 1968
THE BEHAVIOR OF BEAMS RESTRAINED AT THE ENDS AGAINST LONGITUDINAL DISPLACEMENTS HAS BEEN STUDIED ANALYTICALLY TO PROVIDE BASIC KNOWLEDGE OF THE PARAMETERS THAT INFLUENCE THE BEHAVIOR OF SUCH BEAMS AND TO PROVIDE INSIGHT INTO THE BEHAVIOR OF A SIMILARLY RESTRAINED SLAB.

Shear in Reinforced Concrete Beams

2016
In the classic two-dimensional structural studies of beams typically three separate internal forces are identified on any selected section. These are the axial force, P, (tension or compression) that acts along the axis of the member; the shear force, V, that acts in the plane of the section perpendicular to the axis of the member; and the ng moment, M

Industrialized reinforcing system of reinforced concrete beams

1986
The position of reinforcement and its amount and shape have a decisive effect on the performance of a reinforced concrete beam. The use of stirrups is not always necessary, they can be omitted in some cases or replaced entirely or partly with coarse shear reinforcement well anchored at its ends.

Reinforced Concrete Beam and Plate

2012
Concrete plasticity has been described by Chen (1982; 1998) and Nielsen (1984; 1989). Several material models were discussed. Yu’s unified strength theory (Yu’s UST or UST) and the UEPP (Unified Elasto-Plastic Program) are successfully used for structural analysis, as has been described in Chapters 6, 7 and 8.

Reinforced Concrete Beam-Column Connection

Journal of the Structural Division, 1971
RECENT RESEARCH ON THE INTERACTION OF FLEXURAL, SHEAR AND TRUSS ACTION AND A RECOGNITION OF THE INCREASING USE OF HIGH TENSILE STRAIN-HARDENED REINFORCEMENT PROMPTED THIS EXPERIMENTAL RECONSIDERATION OF THE BEHAVIOR OF THE CRITICAL BEAM SECTION AT THE BEAM-COLUMN CONNECTION.
