Seismic 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 کاملBi-directional Seismic Analysis and Design of Bridge Steel Truss Piers Allowing a Controlled Rocking Response
4-legged bridge steel truss piers provide support for gravity, transverse, and longitudinal lateral loads of bridges. Allowing a controlled rocking response for seismic resistance of 4-legged truss piers requires the development of design equations considering ground motions in two horizontal directions and vertical excitation. First, the static kinematic and hysteretic bi-directional behavior ...
متن کاملComparison Study on Neural Networks in Damage Detection of Steel Truss Bridge
This paper presents the application of three main Artificial Neural Networks (ANNs) in damage detection of steel bridges. This method has the ability to indicate damage in structural elements due to a localized change of stiffness called damage zone. The changes in structural response is used to identify the states of structural damage. To circumvent the difficulty arising from the non-linear n...
متن کاملSeismic Retrofit of Bridge Steel Truss Piers Using a Controlled Rocking Approach
This paper investigates a seismic retrofit technique that allows bridge steel truss piers to uplift and rock on their foundation. Displacement-based passive energy dissipation devices buckling-restrained braces, or BRBs are implemented at the uplifting location to control the rocking response while providing additional energy dissipation. The hysteretic behavior of the controlled rocking system...
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...
