The Effect of Tuned Mass Damper on Seismic Response of Building Frames with Uncertain Structural Characteristics
Tuned mass dampers (TMDs) could be used to absorb the input energy of the applied load, and reduce the response of the building frames. However, the effectiveness of TMD in reducing the response of the building frames could be affected by inherited uncertainties in the structural characteristics of the frames. In this study, in order to investigate the probabilistic response of steel moment-res...
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...
متن کاملSeismic Retrofit of Bridge Steel Truss Pier Anchorage Connections (2002-2003)
In assessments of the seismic adequacy of existing steel bridges, the anchorage of steel truss piers to their foundations often has insufficient strength to resist seismic demands. Many other non-ductile failure locations may also exist along the seismic load path that cannot provide adequate seismic performance. Although strengthening is an option, this approach may only transfer damage to ano...
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 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...
