RC Column Material & Geometry (cont.)

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
