Non-Contact Lap Splices in Geometrically Dissimilar Bridge Column to Drilled Shaft Connections
… irregularity for the connection of non-circular bridge columns interfacing directly with circular drilled shafts. However, there is a concern on the safety and cost-effectiveness of such non-contact lap splices because the guidelines in the current AASHTO LRFD code and studies on this type of …

Seismic Performance of Bridge Column-Pile-Shaft Pin Connections for Application in Accelerated Bridge Construction
Bridges with integral superstructures are common in high-seismic regions. The superstructure and substructure are connected using rigid connections in these bridges. However, hinge or "pin" connections may be used to connect columns to pile-shafts to reduce the overall force demand in the integral …

Post-seismic response and repair of earthquake-damaged reinforced concrete bridges
“In bridge structures, column members are typically designed to be the primary source of energy dissipation during an earthquake. Therefore, reinforced concrete (RC) bridges that are damaged in an earthquake tend to have damage to the column members. While many studies have been conducted on …

Behavior of hollow-core fiber reinforced polymer-concrete-steel bridge columns under extreme loading
… fiber reinforced polymer-concrete-steel (HC-FCS) bridge columns under extreme loading. The HC-FCS column consists of a concrete wall sandwiched between an outer fiber reinforced polymer (FRP) tube and an inner steel tube. The steel tube was embedded into a reinforced concrete footing with an …

Seismic Performance of Self-Consolidating Concrete Bridge Columns
… performance of self-consolidating concrete (SCC) bridge columns. This study included literature review, experimental evaluation of concrete mixtures, experimental testing of reinforced concrete bridge columns under combined axial loading and lateral load reversals, and analytical evaluation of …

Seismic Performance of Square Nickel-Titanium Reinforced ECC Columns with Headed Couplers
Current bridge seismic design could be improved by moving towards performance based design to keep bridges operational and keep repair costs to a minimum by reducing damage to column plastic hinges and minimizing residual drifts. These objectives can be accomplished by using innovative materials …

Corrosion Behavior of Corrosion-Resistant Steel Reinforcements in High and Ultra-High Performance Concrete in Chloride Attack Environments
… corrosion rate, and reinforcement mass loss of column specimens were monitored regularly over 24 months in an accelerated aging environment, and the degradation of the axial-load-carrying-capacity of the columns over time was also obtained and discussed. Findings indicate that …

Experimental Studies of Reinforcing Steel and Shape Memory Alloys in Mechanically Spliced Connections for Seismic Application
… bar splices for use in the plastic hinge of a bridge column for use in accelerated bridge construction (ABC). The implementation of couplers in a plastic hinge for ABC is not unique, however coupler application has been limited to regions of low seismic hazard due to lack of knowledge about …

Post-Earthquake Damage Repair and Probabilistic Damage Control Approach for Reinforced Concrete Bridges
… approach (PDCA) for reinforced concrete (RC) bridges. To develop repair methods, first repair objectives were defined. To define repair objectives, internal earthquake damage was quantified and correlated to a series of visible damage states (DSs). Bridge columns are designed to be the primary …

Seismic Performance of Column-to-Drilled-Shaft Connections in Reinforced Concrete Bridges
… are often used to support reinforced concrete bridge columns founded in soft soils or in locations where a small footprint is desired. Increasingly, the shaft is being built with a diameter larger than that of the column, to allow tolerance in the column placement and to facilitate plastic …
