New Technique Braces Buildings against Earthquakes

Researchers at the University of Michigan in Ann Arbor, Michigan have developed a new method for bracing high rise concrete buildings. By reinforcing the concrete with steel fibers, they were able to design coupling beams (beams used to connect walls around openings like windows and door frames) that are both easier to construct and more effective than traditional coupling beams. A test structure using these new beams was shown to be able to withstand a fake earthquake stronger than any real earthquake ever recorded.
