Long-span structures like bridges experience different movements at the supports because of wave-passage, incoherence, and site-response effects. In this study, spatially varying ground motions were used to evaluate seismic vulnerability RC bridges. To gain goal, three prototypes Caltrans reinforced concrete curve with column heights various radii selected for numerical study. The correlated ge...

A laboratory technique suitable for one-piece casting of short or long span bridges and its application to a seven-unit one-piece cast bridge is described. (Received for puhlicution August, 1980. Revised October, 1981.)

The track–bridge interaction is a fundamental concern in the field of railway engineering, which plays an important role optimization design bridges, especially for heavy-haul and high-speed bridges. This paper systematically introduces research status CWR large-span bridges China. evolution process model from simplest elastic bar linear longitudinal resistance to complex beam–rail considering ...

With the trend of variable cross-sections for long-span bridges from truss-stiffened to quasi-streamlined, and then to multiple-box cross-section geometries, the importance of aeroelastic performance is becoming increasingly significant in wind-resistant design. This article shows that there is clearly insufficient qualitative as well as quantitative understanding of turbulence effects on bridg...
