We probe the reliability of monopile support structures designed to support industrial scale turbines along the coastal United States using stochastic models for the wind and wave loadings, and representations of the uncertainty associated with soil properties. The turbine support structure investigated is that promulgated by the National Renewable Energy Laboratory as typical of a monopile sup...

The main objective of this project is to develop a generic framework which will set the basis for achieving more consistent system reliability assessments. The main steps involved in a system reliability assessment, together with the key technical and philosophical issues, will be identified and examined. Their interrelations and relative significance will be assessed in order to link them toge...

This paper examines a methodology for computing the probability of structural failure by combining neural networks (NN) and Monte Carlo simulation (MCS). MCS is a very powerful tool, simple to implement and capable of solving a broad range of reliability problems. However, its use for evaluation of very low probabilities of failure, of the order of magnitude currently found in structural reliab...

In this paper, a more efficient approach for component-level structural reliability analysis using the First Order Reliability Method (FORM) is presented. In this approach, the continuum design sensitivity analysis (DSA) and a two-point approximation (TPA) method are employed to support the most probable point (MPP) search in the random variable space for structural reliability analysis. This a...

According to the problem that for a structure under random loads, the structural fatigue life can’t be directly calculated out by S-N curves and linear Miner cumulative damage rule. Owing to the uncertainty of loads, and the problem of the inaccuracy of calculated structural reliability index for the existence of deviation between measured data in projects and real data, the research method for...

Structural reliability and structural robustness, from different research fields, are usually employed for the evaluative analysis of building civil engineering structures. has been widely used optimization design, while robustness is still in rapid development. Several dimensionless evaluation indexes have defined so far, such as reliability-based redundancy index. However, these based on subj...

Whilst conventional approach in structural design is based on reliability-calibrated factored design formula, performance-based design customizes a solution to the specific circumstance. In this work, an artificial neural network approach is employed to determine implicit limit state functions for reliability evaluations in performance-based design and to optimally evaluate a set of design vari...

the present study was conducted to investigate and formulate the effects of social capital dimensions on entrepreneurial intentions. the population of this study consisted of all fourth year agricultural students of yasouj university (n=196), that by using patten (2002) sampling table, 130 student were selected as the sample using the random simple sampling method. the main instrument of study ...

Due to the existing of various kinds of uncertainties, predicting structural performance is always a great challenge in practical applications. The reliability of structure under the probabilistic uncertainty has been well studied in the past decade. However, the randomness is not the only attribute of reality. This paper attempts to investigate approach for the structural reliability analysis ...

High reliability and operational safety are most important requirements of aerospace products. Structural Safety (Reliability) assessment techniques help to achieve safe designs and also identify effect of uncertainty occur in structural systems of aerospace products. In general the structural safety is evaluated using various statistical methods like Mean Value and Moment Methods. Currently se...
