What is Longitudinal Reinforcement?

Longitudinal reinforcement are the vertical bars, which are in the vertical alignment within the column and horizontal alignment in the slab and beam. They resist bending forces in beam, axial compression in the column and bending stress in slab.

what is Axial Load?

An axial load is any force whether tensile or compressive in nature acting parallel to the centroidal/longitudinal axis of the member. If an axial load coincides with the centroidal axis of the member, then it is called concentric axial load and if an axial load is at a distance from the axis, then it is called eccentric axial load.
