Note. Δ_y, Δ_p, and Δ_u present the yielding displacement, peaking displacement, and ultimate displacement, respectively; P_y, P_p, and P_u stand for the yielding strength, peaking strength, and ultimate strength, respectively; μ was displacement ductility that was obtained as the ratio of ultimate displacement Δ_u to yielding displacement Δ_y of specimens.
