Interaction Diagram of RC Column Specimen The flexural and axial capacity model for RC columns is used to derive an interaction diagram which relates the axial load column capacity with its moment capacity at any given time 120 100 Maximum Axial Load Zero stress in tensile reinforcement, Z=0 (nom inal) Axial Load Capacity, Pn (kips) 80 60 40 20 0 0 20 40 60 80 100 120 140 160 -20 Balanced Failure, Z= -1 COMPRESSION TENSION -40 (nominal) Moment Capacity, Mn (kip-in)
Moment-Curvature Response of Shear-Critical RC Column under Axial & Lateral (Shear) Loading The flexural and axial capacity model for RC columns is used to derive an interaction diagram which relates the axial load column capacity with its moment capacity at any given time 160 M Y =V Y *l 140 120 100 80 60 Moment, M (kip-in) 40 20 0 -7.E-22 1.E-04 3.E-04 4.E-04 5.E-04 7.E-04 8.E-04 9.E-04 1.E-03 1.E-03 1.E-03 1.E-03 2.E-03 2.E-03 2.E-03 2.E-03 2.E-03 2.E-03 2.E-03 3.E-03 3.E-03 3.E-03 3.E-03 3.E-03 3.E-03 3.E-03 3.E-03 4.E-03 4.E-03 Curvature, θ (1/in)
