Reliability Consideration in Shakedown Analysis
Shakedown analysis for ductile rigid frames has shown that a structure can respond linearly at a higher elastic limit after it has experienced some plastic deformation. If the residual...
Probability Model of Load Exceedances under Cyclic Loadings
A probability model for nonlinear load exceedances subjected to a Poisson process with reversible cyclic load pulses was developed and is presented in this paper. A reversible cyclic load...

A Criticism of Statistical Methods in Probabilistic Models in Structural Reliability
The usual statistical models, classical and Bayesian, are not well suited for problems of structural reliability, since here we have rarely as assumed for these models a sequence of identical...
Sensitivity Evaluation of Simulation Methods for Reliability Assessment
Commonly used reliability assessment methods include the first-order methods, second-order methods, and Monte Carlo simulation methods with or without variance reduction techniques. The...
High Order Statistics in Structural Reliability
The new simulation technique described in this paper attempts to avoid the significant amount of arbitrariness involved in the choice of the sampling distribution in the increasingly popular...
Experiences with Experimental Design Schemes for Failure Surface Estimation and Reliability
When using FORM and SORM to predict the probability of failure for a structural component a model for the failure function has to exist. For certain structural components a mechanical...
Slepian Process of a Non-stationary Process
An algorithm for simulating a zero-mean non-stationary Gaussian process over a fixed interval [0,T] with given arbitrary covariance function as well as the associated Slepian model process,...
Inspection Planning for Surface Fatigue Cracks
A reliability based method for planning of inspections to detect surface fatigue cracks is presented. Cracks are described as semi-elliptical surface cracks. The conditions governing fatigue...
Some Remarks on BK-Models for Fatigue Crack Growth
The choice of a model parameter for concentrating the entire uncertainties of a constant load amplitude fatigue crack growth process is shown to be sufficient when reproducing the first...
A Fatigue Reliability Model for Railway Bridges
A fatigue reliability model is described for safety evaluation of steel railway bridges. The model is a function of six independent random variables and can accommodate different types...
A Stochastic Approach to the Fatigue Reliability
In this paper, the stochastic approach, which combines the mixed boundary integral equation method (Lua et al (1992a)) with the First Order Reliability Method (FORM), is applied to study...
Stochastic Finite Element Analysis of a Damped Beam on Random Foundation and Subjected to Fast Moving Loads
The dynamic effect of fast moving loads on a rail is analysed by the perturbation-based stochastic finite element method. The rail is modeled as an elastic beam resting on the Winkler...
Finite Element Dynamic Reliability Analysis with Condensation
This paper presents the use of matrix condensation in stochastic finite element-based reliability analysis of structures subjected to dynamic loading, in the context of modal superposition....
Reliability of Nonlinear Frame Structures by SFEM
A method is proposed for the reliability analysis of nonlinear frame structures with flexible connections. The uncertainty of a connection is represented by a group of random moment-relative...

The object of this study is to develop a framework for considering redundancy in design and load capacity evaluation of highway bridge superstructures. The proposed method consists of...
Structural Reliability and Proof Testing for Highway Bridges
This paper proposes a set of reliability-based proof load factors for highway bridge evaluation, to determine target proof load and load rating. The target safety index used is consistent...
Reliability of Controlled Structures Subject to Real Parameter Uncertainties
This paper presents a systematic and probabilistically consistent approach for determining the likelihood that instability will result from the uncertainty inherently present in a controlled...
Effect of Active Control to Structural Reliability
Most available results in the study of structural reliability deal with idealized mathematical representation of structures. With model supported diagnosis of the structural condition...
