WebMar 2, 2006 · The Morristown Bridge, which is located in Vermont, United States, is a single span steel girder bridge with integral abutments spanning 43.90 m. The deck is a 230 mm thick concrete continuous slab over girders spaced at 2.36 m. The entire concrete deck slab was reinforced with glass FRP (GFRP) bars in two identical layers at the top and the ... WebCertain bridge types, such as reinforced concrete (RC) sla}? bridges with sound piers and abutments, are inherently more resistant to collapse than others. Not a single RC slab bridge collapse was reported among the 33 cases studied by Hadi priono (2). An NCHRP review of field tests also has indicated
