🏗️ Earthquake Building Challenge: Shake Platform with a Braced Timber Frame, Masonry Tower and Tile-Roof House

Design three buildings on a shake platform (braced timber frame, unreinforced masonry tower, stone house with clay-tile roof), pick a quake with magnitude, distance and soil, and watch storey drift, cracking, soft-storey failure, base isolation and collapse driven by a nonlinear shear-building model, with a live seismograph, response spectrum, budget and score.
