Double-composite rectangular truss bridge and its joint analysis

Fem Analysis of Truss Hollow Section Joint

Truss structures are widely used in construction of large-scale buildings. Design of steel structures is standardised in detail through set of European standards called EUROCODE. One of these standards, ENV 1993-1-8 deals with design of joints, but it does not cover the design of conical element for reduction of circular hollow section to the joint. Finite element method was used in this paper ...

Bi-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 ...

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...

Seismic Performance of a Ductile Retrofitted Deck-truss Bridge

Seismic evaluations of many existing deck-truss bridges have revealed the vulnerability of their substructure and members of their superstructure. An innovative retrofit strategy developed by the authors includes replacement of the existing non-ductile end and lower-end bracing with ductile panels by incorporating energy dissipating devices to act as fuses, which can yield and dissipate energy ...
