Abstract: Columns are usually the weak links in conventional bridges with regard to seismic design. Damage of reinforced concrete (RC) columns caused by moderate earthquakes is usually repairable, but significant damage is expected ...

Abstract: Superelastic (SE) shape memory alloy (SMA) is an advanced material that may be used as an alternative to conventional reinforcing steel in civil engineering structures to control residual deformations. The most common SE ...

Abstract: Precast prestressed double-tee girder bridges are common on county bridges in South Dakota. However, the longitudinal joints of these bridges are rapidly deteriorating, causing girder replacement after only 45 years of ...

Abstract: The South Dakota Department of Transportation (SDDOT) allows the use of precast, prestressed double-tee girder bridges in county and local roads because they are economical and fast in construction. However, many of ...

Abstract: A mechanical bar splice, which is known as a bar coupler, is an alternative to traditional lap splicing to connect bars in reinforced-concrete (RC) structures. Although it is feasible to incorporate mechanical bar splices ...

Abstract: The most common type of bridge on South Dakota local roads is a precast prestressed double-tee (DT) girder bridge. For old and/or deteriorated bridges, the estimation of the bridge safe live load is necessary to ensure the ...
