🏢 Earthquake Building Resonance (2D)

A 2D cross-section shear-building shaken by a seismic ground motion, integrating the real single-degree-of-freedom damped-oscillator equation (natural frequency, damping, resonance) with material-specific drift-capacity collapse.

⚙ Under the hood

A 2D cross-section shear building shakes under a simulated seismic ground motion, driven by the real single-degree-of-freedom damped-oscillator equation. Floors sway hardest when the shaking frequency matches the building's natural frequency (resonance), and storeys crack and collapse once interstorey drift exceeds the material's capacity.
