Curved beam bridge is a kind of irregular structure, which has the advantage adapting to complex terrain, but it more vulnerable damage than regular under earthquake. This paper investigates vulnerability curved continuous girder bridges action bidirectional earthquake horizontal earthquake, and difference between side pier intermediate analyzed. Fragility assessment performed using an incremen...

The guardrail is an indispensable part of ballasted track structures on bridges. In order to reveal its influence the track–bridge interaction continuous welded rail (CWR), longitudinal resistance model fastener and influential factors are established through tests. By taking a girder bridge (CGB) for railways as example, stock rail-guardrail-sleeper-bridge-pier integrated simulation developed....

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 ...

Tacoma Narrows Constructors (TNC) is building a new suspension bridge in Tacoma, close to Seattle, Washington State, USA. The new bridge will be built just south of the existing bridge mounted on two caissons, referred to as East Caisson (Tacoma side) and West Caisson (Gig Harbor side). Each pier is about 80’ wide and 130’ long in plan. The mooring system for each caisson consists of two sets o...

Current research investigating ice-covered bridge pier scour has focused on the effects of fully developed ice jams. However, based observations at various stages development, covers are not always developed. This experiment investigated a simulated floating jam’s with constant flow rate. Various channel-spanning cover lengths were tested, along one circular localized cover, and resulting was c...
