Reliability analysis of suspension bridges against buffeting failure
A reliability analysis of suspension bridges against buffeting failure due to gustiness of wind velocity is carried out using the concept of PRA (probabilistic risk analysis) procedure. For this purpose, the bending stresses at the critical nodes of the bridge deck are obtained for buffeting forces using a spectral analysis technique and a finite element approach. For the purpose of reliability...
متن کاملA 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...
متن کاملLong 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 کاملDynamic Reliability Assessment of Long-span Suspension bridges under stochastic traffic flow
For most existing bridges, supporting continuous traffic loads is the basic function. However, in addition to this load, bridges are exposed to environmental (Frangopol and Soliman, 2015 [1]), as well as various other complex loads, that are mostly random in nature, such as earthquake, flow-included loadings, wind and so on. All these loading conditions need to be considered and must satisfy th...
