TL;DR: In this paper, the reliability analysis procedure based on design of experiment (DOE) is combined with the response surface method (RSM) for numerical efficiency, which is constructed initially based on the data on the axial experimental points and updated successively by adding one more experimental point selected using an influence index, until the probability is converged.

TL;DR: An overview of three software for structural reliability analysis developed at the University of California, Berkeley are provided, which include CalREL, FERUM, and OpenSees.

TL;DR: The problems that can be addressed, the underlying algorithms implemented and methodologies of these methods in both ANSYS DesignXplorer and Variational Technology, which is offered in both tools, are described.

TL;DR: The goal of the reported work has been to develop a software tool that fully addresses three aspects (availability, robustness and efficiency) to enable the designer to efficiently and accurately account for uncertainties as they might affect structural reliability and risk assessment.

TL;DR: In this article, the authors developed seismic fragility curves for one and two-story woodframe structures in three locations (Memphis, TN; Carbondale, IL; and Boston, MA) having both moderate snow and seismic hazards.

TL;DR: The paper shows that the LQI model is in harmony with well-established principles of economics, utility theory and recent developments to quantify the progress of nations through indicators of human development.

TL;DR: In this article, the authors developed a general framework of time varying unconditional reliability evaluation of linear elastic multi degree of freedom structures with uncertain parameter subjected to the generalized earthquake ground motion, a non-stationary process both in amplitude and frequency content.

TL;DR: I-PCM as mentioned in this paper employs a simple modification of bivariate integrals based on the additive law of probability to eliminate the overestimation of the failure probability of series systems with highly reliable elements.

TL;DR: The main conclusions drawn at the end of the paper are that the capability of interaction with third party FE codes is a key asset and that the potential of parallel processing, while its importance has been recognized, is not yet exploited.

TL;DR: An overview of the current status of the COSSAN™ software is provided which is an event driven modular general purpose code and the ‘Third Party Communication Tools’ which allow to employ deterministic Third Party (FE-) codes for stochastic analysis without the need to access and modify the third party source code.

TL;DR: In this article, the first and second-order reliability concepts for structural, operational and other systems based on first-and secondorder reliability were made available as early as 1976 by the Technical University of Munich.

TL;DR: Numerical examples show that results of this SVR-based approach for large-scale structural health monitoring are accurate and robust, even when observed data are contaminated with different kinds and intensity levels of noise.

TL;DR: In this article, the authors present a probabilistic approach to minimize the life-cycle cost of inspection and refurbishment of wood poles in a large distribution network, where a key input of probabilism is the life time distribution function of wood pole, though its estimation is often hampered by the lack of data.

TL;DR: In this paper, the authors focused on the optimal seismic design of buildings for the limited planning time horizon considering earthquakes generated from Poisson and non-Poisson processes, and developed an analysis algorithm based on simulation technique, considering detailed seismic information; the evaluation of the linear/nonlinear responses and different structural damage levels; and the assessment of the statistics of the damage cost.

TL;DR: Proban is a general purpose probabilistic analysis program that covers calculation needs for example in structural reliability, and calculates probability, distribution, first passage probability, crossing rate, and related sensitivity measures.

TL;DR: In this article, a new method for the design of structures that minimizes the total expected costs of the structure during its lifetime based on Benders' decomposition is presented, and some tools for sensitivity analysis are introduced, which make it possible to determine how the cost and yearly failure rates of the optimal solution are affected by small changes in the input data values.

TL;DR: In this paper, a stochastic model for the failure of turbine disks including quality assurance procedures is established, based on a fracture mechanics description using both a direct Monte Carlo simulation and a first-order reliability method.

TL;DR: This paper summarizes the ProFES Version 2.0 capabilities with a focus on recent Pro FES enhancements in three major areas related to probabilistic design: design optimization, damage tolerance, and possibilistic-probabilistic analysis.

TL;DR: In this article, an analysis of the modeling error associated with several commonly referred models for predicting shear capacity of reinforced concrete beams were carried out using a database containing results of test beams that was established based on test specimens found in the literature.

TL;DR: UNIPASS™ is a PC-based Windows 32 compliant software engine that can be utilized independently, as a stand-alone tool, or integrated with deterministic software tools to perform complex probabilistic analysis.

TL;DR: In this article, the strength reliability of randomly heterogeneous beams is studied, and an improved analytical solution is found by a new, optimized functional perturbation method (FPM), which is achieved by two operations: generalizing the previously used FPM to account for multifunctional dependency and choosing the perturbations to be around the proper homogeneous case for each type of morphology.
