Design optimization of cable-stayed bridges
… thesis is to achieve a basic understanding of cable-stayed systems. Issues to be treated are the diachronic evolution of cable-stayed bridges, including the advantages, the limitations and the basic design concepts of these indeterminate systems. During this project, the design of typical …

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 …

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 …

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 …

Seismic behaviour of cable-stayed bridges : design, analysis and seismic devices
The social and economical importance of long-span bridges is extremely large; cablestayed bridges currently span distances ranging from 200 to even more than 1000 m, representing key points along infrastructure networks and requiring an outstanding knowledge of their seismic response. The objective …

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 …

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 …

Long term behavior of cable strayed bridges
… for highly indeterminate structures like cable stayed bridges where the stresses are related to the geometric configuration of the structure itself. In concrete cable stayed bridges, in fact, the increase in the deformation of the deck and the pylons over time leads to a decrease in the …

Design of a cable-stayed precast post-tensioned box girder bridge
An overview of current practice in the field of cable-stayed post-tensioned precast box girder technology and construction is presented. Likewise, a preliminary design for a 600 foot main span cable-stayed post-tensioned box girder bridge is presented. The analysis considers dead load, and live …

Experimental and CFD Study of Wind-Induced Response for Bridge Cables with Ice accretion
Cable-stayed bridges are massive structures which rely on their structural elements such as deck girder, towers and stay-cables for their stability. The bridge stay-cables can be considered as the most flexible elements of the cable-stayed bridges, and thus their structural stability integrity is …

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 …

Wind-induced dynamic response of bridges
… constant drive for longer spans in suspension or cable-stayed bridges forces designers to give even more care to wind load. The Golden Gate Bridge (1280 m, San Francisco, built in 1937), which held the record for the longest span for 27 years, is now a distant 7th to the Akashi-Kaikyo (1991 m, …

COMPUTATIONAL FLUID DYNAMICS SIMULATION OF RAIN-WIND-INDUCED VIBRATION OF STAY CABLES
… the rain-wind induced vibration (RWIV) of stay cables in cable-stayed bridges has been investigated extensively by researchers around the world. However, the underlying excitation mechanism is still unclear. Recently, computational fluid dynamics (CFD) simulation has been widely applied in the …
