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 کاملAnalysis of structural reliability under parameter uncertainties
Formulation of structural reliability requires selection of probabilistic or physical models, which usually involve parameters to be estimated through statistical inference — a process that invariably introduces uncertainties in parameter estimates. The measure of reliability that incorporates these parameter uncertainties is termed the predictive reliability index. Methods for computing this m...
متن کاملMultimode coupled flutter and buffeting analysis of long span bridges
In this paper, the equations of structural motion are expressed in time-invariant state-space equations by expressing the frequency dependent self-excited forces in terms of rational functions. Accordingly, the multimode coupled flutter analysis is reduced to evaluate the eigenvalues of a constant matrix at each prescribed wind velocity. This formulation is computationally efficient in comparis...
متن کاملSystem Reliability Models for Bridges *
There is a need for efficient bridge evaluation procedures. A considerable number of existing bridges in the United States require repair and/or replacement. Accurate estimate of the current strength and the remaining life time is essential for optimum distribution of the available limited resources. The major parameters which determine the structural performance are random variables. Statistic...
