Active Control of a Cable -Stayed Bridge Against Earthquake Excitations
The performance of the LQG- and H2-based controllers was less than satisfactory, in the sense that the performance was not as good for the evaluation model as it was for the design model. The controller designed with mu-tools, on the other hand, was robust, and the resulting evaluation criteria …

Dynamic analysis and active control of two cable-stayed bridge
… the transient and steady state response of a two cable-stayed bridge has been investigated. The bridge has been modeled as a two degree freedom system in bending and torsion, excited by both buffeting and self-excited loads. The existing suspension cables have been used as active tendons by which …

Static and Dynamic Analyses of a Long-Span Cable-Stayed Bridge with Corroded Cables
… and dynamic behavior of the Stonecutters Cable-Stayed Bridge, which is the third longest cable-stayed bridge in the world, when a group of 8 cables is damaged by corrosion. In this thesis, the reduction in cable cross-section area is used to simulate the corrosion level. The corroded …

Valuable bridges : cable-stayed bridges and value engineering in American civil engineering culture, 1969-1979
A history and theory of cable-stayed bridges in the context of a cultural discourse on civil construction projects' value, this thesis studies the significance of cable-stayed bridge designs to 'value engineering' objectives for major highway bridge projects of the 1970s. This study of preliminary …

Time-dependent analysis of cable-stayed bridges
Cable-stayed bridges are constructed using the cantilever method of construction and generally take a long time to build. In a concrete cable-stayed bridge, concrete properties change with time causing a change in the position of the neutral axis. In different parts of a concrete bridge creep and …

Wind effect on long span bridge
… different types of reactions of long span bridge under wind load, such as vortex shedding, flutter and buffeting. Since all of these conditions have the chance to damage bridge structure, we calculate the particular wind speed and magnitude that will maximize the reaction. To check if the …

Bayesian-based Finite Element Model Updating, Damage Detection, and Uncertainty Quantification for Cable-stayed Bridges
Long-span bridges are important components of civil infrastructure systems because they are vital links in transportation systems. Therefore, as bridge systems age, understanding the safety and serviceability performance of structural components of these systems through structural health monitoring …

Optimization of Cable-stayed Bridges at the Conceptual Design Stage
Conceptual design of cable-stayed bridges, which defines the structure’s geometry and typology in the early stages of design, has significant influence on the structure’s efficiency, cost, aesthetics, and constructability. However, conventional design approaches for bridge design places greater …

Dynamic behaviour of curved cable-stayed bridges
During the last decades, curved cable-stayed bridges have been regularly accepted due to their ability to cross long spans, for aesthetic reasons because of their enhanced geometric configurations and to the reduced costs involved in the bridge and roof construction. However, such structures are …
