Reinforced Concrete Columns - MCEER

Capacity Models of RC Column
Specimen: Axial Capacity
Axial Capacity of undamaged RC column:
P N = 0.85*f C ’*(A g – A SL ) + f YL* A SL
..where f C ’ concrete compressive strength, A g is the gross
concrete area, A SL is the longitudinal reinforcement area,
f YL is yield strength of longitudinal steel
P N
= 0.85*(3ksi)*[36in 2 -0.884in 2 ] +
(70ksi)*(0.884in 2 )
P N
= 151.43 kips
