Stiffness-Displacement Correlation from the RC Shear Wall Tests of the SAFE Program: Derivation of a Capacity Line Model

Figure 15

Predicted vulnerability line for walls T03, T04, and T05, according to one unique piecewise line model, in terms of displacement for every level of PGA based on the response spectrum for 5% damping ratio. Discrete (“star”) points represent the recorded maximum experimental response at the applied earthquakes.
