Kernel Method in Importance Sampling Density Estimation
The use of the kernel method to estimate the optimal importance sampling density is introduced. This method requires samples generated from an initial direct Monte Carlo run to construct...

Expected Failure Time of Fiber Bundle Systems Subject to Gaussian Load Processes
Methods are developed for estimating the reliability and failure time of Daniels systems subject to Gaussian load processes. These systems consist of a set of parallel fibers and can carry...

Two Applications of Asymptotic Laplace Integrals in Structural Reliability
The concepts for asymptotic analytical solutions to so-called Laplace integrals are briefly reviewed. It is shown how integrals occurring in structural reliability can be transformed so...

Detection of System Nonlinearity
A method for detection of linear/nonlinear characteristics of mechanical systems excited by stationary Gaussian processes is presented. Linear systems under consideration show always a...

System Identification Methods for Fault Detection and Diagnosis
Faults refer to any unexpected changes or modifications of existing structures resulting from extreme loads or other abnormal loading and environmental conditions. Such faults may effect...

Statistical System Identification of Structures
A general unifying approach to system identification is presented within a Bayesian statistical framework to explicitly treat the inherent uncertainties. It is shown that selecting the...

Experience in Model Adjustment by Parameter Estimation Methods
If the computational model is uncertain and if measured data of the system exist, system identification approaches lead to an improved computational model with known confidence. After...

In this paper, control of nonlinear oscillations of a single-span flexible bridge with light damping is examined to improve bridge safety and reliability. The control forces are applied...

Reliability of Control Systems of Building Structures by Active Tendons
In this paper, a numerical assessment on the reliability of a control system of building structures by active cables is performed. Some control experiments on a 23-story shear-wall building...

Safety Evaluation of a Tall Building
This paper uses the extended Kalman filter to perform the system identification of a tall building with the aid of recorded accelerograms obtained from strong-motion seismographs. The...

Application of Probabilistic Approach for Crack Growth Damage Accumulation in Metallic Structures
Two stochastic crack growth approaches (i.e., 'general' and 'analytical') are presented and evaluated for predicting the crack growth...

Reliability Analysis of Weldings Considering Defects
The welds generally represent the most critical part of large structural systems, i.e. offshore structures. Hence they affect significantly the structural reliability. A realistic model...

Stochastic Propagation of Semi-Elliptical Surface Cracks
Random propagation of a semi-elliptical surface crack is investigated as a bivariate stochastic process. Under a few assumptions, a probability distribution of the surface crack propagation...

Fatigue Reliability of Steel Structures in the Presence of Residual Stresses
An extended model for the assessment of fatigue reliability of steel structures in the presence of residual stresses is developed. The model explicitly includes the uncertainties of the...
