1. Abstract In this paper a robust and efficient methodology is presented for treating large-scale reliability-based, structural optimization problems under seismic loads using the pushover analysis method. The optimization problem is solved with the Evolution Strategies method, while the reliability analysis is carried out with the Monte Carlo simulation method. In order to reduce the excessiv...

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...

Structural reliability problems involving the use of advanced finite-element models of real-world structures are usually defined by limit-states expressed as functions referred to as limit-state functions of basic random variables used to characterize the pertinent sources of uncertainty. These limit-state functions define hyper-surfaces referred to as limit-state surfaces in the high-dimension...

Consideration of fracture mechanics reliability during the design process can assist in the prevention of failures of structural and mechanical components subject to fluctuating loads in service. Explicit consideration of the reliability of structural and mechanical components provides the means to evaluate alternate designs and to ensure that specified risk levels are met. Probabilistic fractu...

The objective of this paper is presenting an approach for reliability sensitivity estimation of linear structural systems subject to dynamical excitation characterized as a Gaussian process. The paper represents an extension of some ideas proposed previously in the context of sensitivity analysis. Novel aspects include the use of the Bootstrap method for assessing the error associated with the ...

In this paper a brief overview of methods to assess the reliability of mechanical systems and structures is given. A selection of computational procedures, stochastic structural dynamics, stochastic fatigue crack growth, and reliability based optimization are discussed. It is shown that reliability based methods may form the basis for a rational decision making.
