Introduction
RFT. Required for Flexure
RFT. Required for Shear
Types of Shear Reinforcement
Critical Section for Shear 1. Case of Distributed Loads
Critical Section for Shear 2. Case of Concentrated Loads
Check of Section Adequacy for Shear
Design of Shear Reinforcement A. Vertical Stirrups
qsu = qu ‐ Astr =

Astr,min.=
. . b. s
s = spacing between stirrups (Not more than 200 mm) A(one branch) =
n = number of branches
b < 40 cm b ≥ 40 cm
Design of Shear Reinforcement B. Inclined Stirrups
Design of Shear Reinforcement C. Vertical Stirrups + Bent Bars
