That is why with funding from the National Science Foundation, engineers at Texas A&M University are leading an NSF-funded collaborative research effort with the University of Colorado-Boulder to investigate alternative bridge structures. Traditional bridge columns are cast as one piece, which means that as the earth shakes, these structures crack like a stick at both ends. The team has proposed one possible alternative: hybrid sliding-rocking or HSR columns, which are built as a series of individual concrete segments stacked on top of each other and held together by steel cables that allow the columns to shift and rock without sustaining structural damage. By preventing bridge damage we can maintain access to the affected areas immediately after an earthquake, saving lives and accelerating recovery of affected communities.\n
