The team setting the stage in seismic Seattle for a 58-story composite steel frame calls the project “a game-changer”

Earlier this month, just over two years after Los Angeles passed a law requiring seismic retrofits of older, nonductile concrete buildings, the city’s Dept. of Building and Safety began sending compliance orders to owners.

An initial reconnaissance of the damage from the Sept. 19 Puebla-Morelos earthquake that killed over 300 people and toppled over 40 buildings in Mexico City found that seismic building codes—put in place after a 1985 deadly quake—were effective, according to a Stanford University professor.

Early indications are that code revisions after 1985 quake had a positive effect — when adhered to.
