Seismic Displacements Reduction for a Long-Span Cable-Stayed Bridge

Advanced Materials Research, 2011
Floating or semi-floating systems are usually employed for long-span cable-stayed bridges to lengthen their fundamental periods, and accordingly, to reduce their seismic inertial force, but the structures’ seismic displacements could be increased by utilizing these systems. Taking Yong-jiang railway cable-stayed bridge which has a low center of gravity

An Analysis Technique for Long-Span Cable-Stayed Bridges

International Journal of Space Structures, 1987
Long-span cable-stayed bridges have been growing in importance in the last few decades. The behaviour of this bridge type under vertical load is studied, and a structural model for its analysis is presented. The model accounts for the nonlinearity of the cables and is shown to represent the actual behaviour of the bridge deck with sufficient accuracy.

Travelling Wave Effect Analysis of Long-Span Cable-Stayed Bridge

Advanced Materials Research, 2011
The vertical distance is generally greater of long-span cable-stayed bridge, while the velocity of seismic wave propagation is certain, therefore, the incentive suffered of long-span cable-stayed bridge’s pier is not the same time, but there is a certain time interval.

Health-monitoring methods for long-span cable-stayed bridges

Infrastructure Asset Management
It is important to consider the impact of non-uniform excitations on long structures, including bridges. This study investigates how the dynamic behaviour of a cable-stayed bridge is impacted by multiple sources of support excitation. The bridge is simulated by using the Abaqus software.
