Answer:
Shear resistance of a inclined stirrup is given by
Vᵇ = Asb(0.95*Fy)(cos α - sin α*cotβ) ((d-d')/sᵇ)
Explanation:
The shear resistance is checked in accordance with BS8110: Part 1, section 3.5.5. Shear resistance of a inclined stirrup is given by
Vᵇ = Asb(0.95*Fy)(cos α - sin α*cotβ) ((d-d')/sᵇ)
where,
Vᵇ=design shear resistance of inclined bars
Asb=cros-sectional area of the inclined bars
Fy=characteristics strength of the stirrups
α=angle between the inclined bars and the axis of the beam
β=angle between the compression strut of inclined bars and the axis of the beam
sᵇ=spacing of the inclined bars
d= effective depth and d'=effective depth minus cover to reinforcement
The shear stress is given by
v=V/bd
where V is the shear force due to ultimate loads. If v is shear stress
