Cable-stayed bridges are one of the most popular types of long-span bridges. The structural behaviour of cable-stayed bridges is sensitive to the load distribution between the girder, pylons, and cables. The determination of pretensioning cable stresses is critical in the cable-stayed bridge design procedure. By finding the optimum stresses in cables, the load and moment distribution of the bri...

Before the recent reconstruction, significant corrosion damages were observed on deck system of ?170-year-old Széchenyi Chain Bridge. Therefore, an advanced reliability analysis-based study is executed to assess risk failure structure in its situation until refurbishment starts. The current paper has aim introduce applied assessment method for analysis and damage grade determination historical ...

This paper presents a methodology to optimize the cable system in cable-stayed bridges, whose main novelty is take into account accidental breakage of one within design process. To this end, multi-model optimization strategy proposed by establishing constraints on both intact and damaged models. The dynamic effect accounted for models application impact loads at tower deck anchorages. objective...

Accepting the challenge of the future in the field of civil engineering smart structure applications, the province of Manitoba is undertaking the responsibility of constructing the first bridge in Canada totally prestressed and reinforced for shear by cru:bon fibre reinforced plastic (CFRP) reinforcement. Portion of the concrete deck slab is also reinforced exclusively by FRP reinforcements. Th...

The Bridge Bidding Practice System allows bridge players to practice and refine their bidding strategies. Users are able to practice bidding with their partners as well as by themselves. The system has been designed so that the user can create decks (sets of four hands) in which they assign rule(s) to specific players’ hands. Once a deck has been dealt, each player can place his or her bids. Af...

This paper investigates the induced stresses in circular single deck roofs floating on seismically excited storage tanks. Equations of motion are derived using variational principle. Response of deck floating roofs is evaluated for two different classes of ground motions; near-source and long-period far-field records. Besides time histories and frequency contents for a specific tank, peak value...

Abstract Massive coastal bridges were damaged in Hurricanes Ivan (2004) and Katrina (2005), considerable efforts have been devoted to the studies of wave forces acting on bridge decks since then. When hurricane tsunamis approach zones, mean water level is elevated, making it possible for incident hit deck directly. The study force essential investigation failure mechanism, a literature review w...

the vibration of cable-stayed bridges subjected to the passage of high-speed trains is studied in this article. the moving train includes a number of wagons, each of which is modeled as a four-axle system possessing 48 degrees of freedom. the car model is nonlinear and three-dimensional and includes nonlinear springs and dampers of primary and secondary suspensions, dry friction between differe...

The Øresund Bridge opened in July 2000. It is the most striking part of the fixed link across the Øresund connecting Copenhagen (Denmark) and Malmø (Sweden), which further includes a tunnel and an artificial island. The bridge is equipped with a PC-based continuous monitoring system, capable of measuring both static and dynamic quantities such as temperatures, wind characteristics, air humidity...

In this paper, the effect of skew angle on reinforced concrete bridge decks is presented by using grillage analogy. The actual deck system represented an equivalent longitudinal and transverse beams. A span 26m simply supported taken as case study to obtain values bending moment' s distribution versus length for one type skewness results are compared against moments right bridge. analysis were ...
