Prefabricated segmental bridge designs that have helped speed construction and save money in many parts of the country may also have a place in seismically active regions, according to recent tests conducted by the University of Buffalo’s Department of Civil, Structural and Environmental Engineering, and its Multidisciplinary Center for Earthquake Engineering Research (MCEER). As part of a Federal Highway Administration-funded project exploring seismic response of Accelerated Bridge Construction (ABC) systems, the research team 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
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.
