EARTHQUAKE ENGINEERING / 04

Seismic Retrofit Lab

Stiffen. Dampen. Let the ground move.

Frame stiffness Story damping Base isolation

Set frame stiffness, damping and base isolation within budget. Run an 8-second synthetic ground-motion test. Keep interstory drift below the limit. Use the traces to compare revised designs.

Model, controls & source

A reduced four-story shear-building model, adapted from lo-th/phy spring-and-damper configuration and MathTool interpolation/damping helpers (MIT). Ground motions are synthetic, not real earthquake records. Not a structural design tool.
