This project studies effective configurations of self-centering devices in the seismic retrofit of curved bridges for control of longitudinal and lateral forces. Reparability of bridge columns is investigated experimentally. A seismic retrofit and repair technique using a Carbon Fiber Reinforced Polymer...

 

Perception-reaction times (PRT) and deceleration rates are critical components in the design of highways and streets. This research has several objectives, including 1) evaluate differences in PRT and deceleration rates between crash and near-crash events, 2) assess the correlation between PRT and deceleration...

 

Concrete infrastructures in cold areas such as South Dakota tend to experience early deterioration that is mostly triggered by steel corrosion. The corrosion is initiated by chloride penetration through cracks in the concrete. Fiber reinforced concrete (FRC) is known to be a good alternative to conventional...

 

Roadside barriers are the primary structural safety devices on surface roads. They can be made from any material as long as they can absorb the energy involved in an impact scenario. One material that has that potential is Ipe, which is a hardwood material that has relatively high strength compared with...

 

Expanded Polystyrene (EPS) geofoam is a super-lightweight material used in various transportation engineering applications. It has been particularly successful as an ultra-lightweight alternative to earthen, geosynthetic reinforced soil (GRS), and mechanically-stabilized earth (MSE) embankment systems...

 

The ultimate objective of this project was to develop widely accepted recommendations on self-consolidating concrete (SCC) mixture design for its use in WisDOT bridge projects. This project investigated the effects of material constituents on the material properties of trial SCC mixtures made from precasters...

 

The high amount of confining lateral steel required by seismic design provisions for rectangular bridge columns can cause steel congestion. The high amount of confining steel may hinder the placement of conventional concrete (CC). Self-consolidating concrete (SCC) eliminates or reduces concrete placement...

 

Connections between precast concrete elements must be able to withstand significant stresses and deformations in earthquakes. The grouted splice sleeve (GSS) connector is being considered for connecting footing, column, and cap beam elements in accelerated bridge construction (ABC). There are limited...

 

Grouted Splice Sleeve (GSS) connectors are being considered for connecting bridge columns, footings, and pier caps in Accelerated Bridge Construction (ABC). A repair technique for precast reinforced concrete bridge column-to-footing and column-to-pier cap joints constructed with GSS connectors has been...

 

The objective of this project is to find effective configurations for using buckling restrained braces (BRBs) in both skewed and curved bridges for reducing the effects of strong earthquakes. Verification is performed by numerical simulation using analytical models of existing bridges when BRBs are implemented...
