Displacement-based Design<br />
• Based on initial stiffness and an effective first<br />
mode mass<br />
• Direct use of the Displacement Response Spectra<br />
for elastic response<br />
• Considers the relationship between inelasticelastic<br />
response of SDOF (Miranda – 90 percentile)<br />
• Definition of curvature and displacement ductility<br />
– Strain limits for concrete and reinforcement<br />
– Foundation flexibility<br />
