RISSeismic Performance of Precast Prestressed Concrete Bridge Girders Using Field-Cast Ultrahigh-Performance Concrete Connections
Publisher: American Society of Civil Engineers
Abstract: Precast concrete bridges have many advantages over cast-in-place construction. Prefabrication typically requires less time at the site due to the ease of installation. Furthermore, production in a controlled environment ...

Ground Motion Duration Effects on Hysteretic Behavior of Reinforced Concrete Bridge Columns
Publisher: American Society of Civil Engineers
Abstract: This study examined seismic behavior under long-duration ground motion in flexural-dominated reinforced concrete bridge columns designed per modern seismic design codes. Two column specimens with identical design parameters ...
Characterization of a Roller Seismic Isolation Bearing with Supplemental Energy Dissipation for Highway Bridges
Publisher: American Society of Civil Engineers
Abstract: A new roller seismic isolation bearing is developed for use in highway bridges. This new bearing uses rolling of cylindrical rollers on V-shaped sloping surfaces to achieve seismic isolation. The bearing is characterized ...
