1,500 pieces of shear reinforcement
, - about 1 050 m 2 of construction clay, - approx.
A simply supported beam without shear reinforcement
under four-point bending is considered to validate the proposed theoretical method (Walraven, 1978).
Longitudinal bottom reinforcement [FORMULA NOT REPRODUCIBLE IN ASCII] mm, top reinforcement [FORMULA NOT REPRODUCIBLE IN ASCII] mm and shear reinforcement
[FORMULA NOT REPRODUCIBLE IN ASCII] mm.
For flexural and shear reinforcement
, deformed and plain rebars of diameter 10 and 6 mm were used, respectively.
Deformed Steel Fibers as Minimum Shear Reinforcement
in Deep, Prestressed Concrete Hollow-Core Slabs.
So, a minimum amount of shear reinforcement
The mild steel flexural reinforcements used were 2#13 bars 2#10 hanger bars and shear reinforcement
included #10 U-stirrups.
An artificial network model was developed to measure the ultimate shear strength of steel fibrous reinforced concrete corbels (SFRC) without shear reinforcement
(Kumar, Barai 2010).
The concrete does have a higher initial unit cost than conventional concrete, but it can be optimized for applications (such as the reduction of shear reinforcement
in a beam), eliminating some of the costs associated with conventional concrete applications.
The formwork stays in place after the concrete has cured and acts as axial and shear reinforcement
, as well as serving to confine the concrete and prevent against environmental effects, such as corrosion and freeze- thaw cycles.
the same principles as for the strength of diagonal section for RC beam without shear reinforcement
Beams without shear reinforcement
develop a shear crack pattern after the first few cycles; deformation increases only slightly.
