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

Table 4

For every wall specimen, identified parameters of RDL with maximum and standard errors of the model predictions by using the response spectrum of the applied earthquakes with damping ratios of = 4, 5, 6, or 7%.

The tests on walls T01 and T02 did not follow the same design scheme as the rest of the walls and their results are used in this table only for the identification of the model and not for determination of the prediction error.
#By using  Pa, instead of  Pa, in the model (see Section 3.8), the obtained error was different in the cases shown in brackets in this table.
