Prefabricated segmental bridge designs not only help shave time and money off construction but also may perform well in seismically active regions, according to recent tests conducted by the University of Buffalo’s Dept. of Civil, Structural and Environmental Engineering and its Multidisciplinary Center for Earthquake Engineering Research. As part of a Federal Highway Administration-funded project exploring the seismic response of Accelerated Bridge Construction systems, the engineering research team in May erected a half-scale, 60-ft-long, eight-segment, post-tensioned superstructure supported by 10-ft, 5-in.-tall hollow piers on 10 x 10-ft concrete foundation blocks. The blocks were mounted on twin shake tables at the
The 2016 Summer Olympics boating and swimming events have put an international spotlight on what has been a long-running problem in Rio de Janeiro—untreated sewage and trash are clogging up major bays and waterways.
