Variables Used
Area of longitudinal reinforcement for columns - (Measured in Square Meter) - Area of longitudinal reinforcement for columns is defined as area of vertical reinforcement which is provided to absorb the bending tensile stresses in the longitudinal direction.
Factored axial load - (Measured in Newton) - A factored axial load is defined as an axial load multiplied by a certain factor designated by codes of practice to drermine the strength of a structural members such as reinforced concrete.
Characteristic compressive strength - (Measured in Pascal) - Characteristic compressive strength is the definite theoretical value of the material in which, when the material has actually tested the probability of getting higher results.
Area of concrete - (Measured in Square Meter) - Area of concrete is defined as concrete area in beam or column excluding reinforcement.
Characteristic strength compressive reinforcement - (Measured in Pascal) - Characteristic strength compressive reinforcement is the strength of compressive reinforcement.
