This paper provides a variety of viewpoints to illustrate the mechanism of the deck-stay interaction with the appropriate initial shapes of cable-stayed bridges, which is validated by a symmetrical structure. Based on the smooth and convergent bridge shapes obtained by the initial shape analysis, the one-element cable system (OECS) and multi-element cable system (MECS) models of the symmetric h...

This paper investigates the elastic-plastic seismic behavior of long span cable-stayed steel bridges through the plane finite-element model. Both geometric and material nonlinearities are involved in the analysis. The geometric nonlinearities come from the stay cable sag effect, axial force-bending moment interaction, and large displacements. Material nonlinearity arises when the stiffening ste...

A cable-stayed bridge recently constructed by the Ohio Department of Transportation incorporates measures put forth by a Federal Highway Administration study to mitigate stay motion. In following recent trends, the stays at this bridge are built without the use of grout for the purposes of inspection and, if necessary, replacement. Several experiments were performed to determine the viability o...

This paper describes the development, updating and validation of the numerical modelling of the bridge-vehicles system of a new cable-stayed bridge (Salgueiro Maia Bridge, in Portugal), presenting several comparisons between calculated and experimental results, associated to the modal analysis, static and dynamic tests of the bridge under controlled heavy roadway traffic.

Probabilistic system-reliability methods have the potential to assist designers in better understanding the ultimate global behavior of bridges, thus leading to more economical, rational, and reliable structures. Nonetheless, these techniques are not currently broadly used in North American bridge engineering practice. Using a sample cable-stayed bridge design, a study is conducted to assess th...
