NOVA, the highest rated science series on television, recently aired a segment on the Colorado State University-led NEES-Soft project that tested Simpson Strong-Tie® Strong Frame® special moment frames as a seismic retrofit solution for soft-story buildings. Simpson Strong-Tie and our special moment frame were prominently featured in the clip. You can watch the entire “Making Stuff Safer” episode on PBS here.
Today the NEES-Soft project has begun testing the steel Simpson Strong-Tie® Strong Frame® Special Moment Frame as a retrofit option for soft-story buildings at the NEES outdoor shake table facility at UC San Diego. The testing is focused on validating the FEMA P-807 design procedure, which attempts to create a least-cost retrofit solution by only retrofitting the garage areas of problem buildings.Continue Reading
In February 2007 I had the opportunity to volunteer for a Soft-Story Sidewalk Survey for the San Francisco Department of Building Inspection. The purpose of the survey was to inventory buildings in San Francisco that appeared superficially to have soft or weak first stories. The volunteers were given a list of addresses to review and we recorded if the building was more than three stories tall, had five or more dwellings, and estimated what percentage of the ground level had openings in the walls. No structural analysis going on, just counting stories, mailboxes, doors and windows.
