Investigation Of Northeast Extreme Tee (Next) D Beam Bridges As An Alternative To Precast Hollow Core Bridges: An Exploration Of Appropriate Slab Design Forces, Daniel Deery

All Theses

Adjacent precast, prestressed concrete beam bridges have become a popular solution throughout the country because deck forming can be eliminated and construction is rapid. In South Carolina, adjacent beam bridges primarily consist of flat slab or hollow core sections, and they are currently only used on secondary, low-volume, short-span bridges. Durability and load sharing issues stemming from cracking, however, have caused concern with the longevity of these bridge types. Thus, the South Carolina Department of Transportation (SCDOT) has sought an alternative to the flat slab for short span bridges that can be used on high volume roads without an overlay. …
