Peak acceleration a single oscillator of period T feels in this shaking (5 % ... your damping). Dots mark each building's period: the higher the dot, the harder it is shaken. Shaded band = ground dominant period.
Peak inter-storey drift so far for the selected building. Amber = cracking starts (20 % of limit), red = illustrative failure limit.
Roof displacement relative to the ground (cm) for the three buildings, with the ground acceleration trace. A vertical tick marks where a building crossed its drift limit.
