Long Span Bridges
Population growth followed by the dramatic increase and demand for new services created an urgent and overwhelming need for infrastructures of civil engineering structures. However, the current infrastructure work using various techniques and conventional materials for construction will not solve the traditional and continuous deterioration of concrete structures due to corrosion of steel. One ...
متن کاملNew frontiers in aerodynamic tailoring of long span bridges: an advanced analysis framework
Significant developments in bridge aeroelastic analysis have been made utilizing realistic aerodynamic force modeling for bridges with bluff sections under turbulent winds. With these developments as a background, this paper highlights state-of-the-art developments in the aeroelastic analysis and identifies new frontiers in aerodynamic tailoring of long span bridges. Challenges in the aeroelast...

15 صفحه اولA Genetic Algorithm Approach for Performance Evaluation of Long Span Suspension Bridges
In this paper, several static and deformability parameters of a long suspension bridge are investigated using a genetic algorithm based approach. For each parameter, a genetic algorithm sets the worst loads combination considering both vertical and longitudinal loads. Ten thousand of different loads combinations are considered for each genetic analysis. In this way is also possible to investiga...
