Experimental Study of a Controlled Rocking Bridge Pier
Controlled rocking of steel braced frames has been proposed for the seismic retrofit of structures. The controlled rocking approach allows a frame to uplift from its support at the base-of-column to foundation interface while displacementbased steel yielding devices are implemented at the base location to control the response. Past studies have focused on analytical investigations of the respon...
متن کاملExperimental seismic testing of a controlled rocking bridge steel truss pier
The experimental seismic testing of a 1/5-length scale model, slender bridge steel truss pier was conducted to investigate the use of a controlled rocking approach as a means of seismic protection. The controlled rocking approach allows the pier to uplift from its base, partially isolating the structure, while passive energy dissipation devices (steel yielding devices, fluid viscous dampers) ar...
متن کاملSeismic Testing of a Bridge Steel Truss Pier Designed for Controlled Rocking
Shake table testing of a 1/5 scale model of a slender bridge steel truss pier that uses a controlled rocking approach as a means of seismic protection was conducted. The controlled rocking approach allows the pier to uplift from its base while passive energy dissipation devices steel yielding devices or fluid viscous dampers are implemented across the uplifting location to control the response....
متن کاملSeismic Retrofit of Pile Group Foundation with Thickened Caps
The case studied in the paper proves that thickening the pile cap is an effective seismic retrofit alternative to strengthen a pile group foundation. Unlike the typical seismic retrofitting of foundation, the proposed method eliminates the need to drive long piles into existing bridge substructures, substantially reducing cost, construction time and traffic interruption. The method thickens the...
متن کاملSeismic Retrofit of Bridge Steel Truss Pier Anchorage Connections
In assessments of the seismic adequacy of existing steel bridges, the steel-to-concrete anchorage connections typically found at the base of steel truss piers can be potentially vulnerable, having little to no ductility and inadequate strength to resist seismic demands. Many other non-ductile failure locations may also exist along the seismic load path. Failure would result in unacceptable perf...
