The graph shown in Figure represents a site$-$specific average design spectrum for elastoplastic structures with $2\%$ damping and a ductility factor of $5.$ On the basis of this design spectrum, estimate the lateral strength for which a single$-$degree$-$of$-$freedom structure with a weight of $10$ kips, natural period of $2\mathrm{.}5$ seconds, and damping ratio of $2\%$ should be designed if: THE structure cannot resist inelastic deformations, and if : THE structure is capable of withstanding inelastic deformations as large as $5$ times its yield deformation.
