This is very important topic regarding interview for Civil engineer.
This topic will provide basic concept of this topic. #Ties-Used in column.
To resist the tension
To hold the longitudinal bars in position in the forms while the concrete is being placed.
to avoid buckling of longitudinal bars.
Bracing bars
#stirrups-
Used in beam
to resist shear stress and bending stress
To hold the longitudinal bars in position in the forms while the concrete is being placed
Shear bars
#Spirals-
Helical/Spiral bars are wrapped around the circular column.
The Spiral reinforcement helps to support in the transverse direction.
The lateral expansion of the concrete is restrained by the spiral.
To hold the main longitudinal reinforcement in its position and to increase the column ductility before failure.
