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 growing need to collect, store and analyze the huge volumes of data collected from infrastructure project stakeholders is generating a new growth area for construction-sector firms, IT vendors and professionals.
