Hybrid Model for Structural Reliability With Imprecise Probabilistic Characteristics
نویسندگان
چکیده
-A hybrid model of a probabilistic and non-probabilistic reliability theory is developed to predict the structural reliability when the probabilistic characteristics parameters of structural properties are imprecisely known. In this study, these parameters are described by appropriate ellipsoid. Interval of the structural reliability will be sought, i.e. estimating the worst possible reliability and the best possible reliability by ellipsoid-bound convex model method. A numerical example of a 60-bar power pagoda is used to illustrate the feasibility and validity of the proposed theory. Key-Words: Structural reliability; Reliability interval; Hybrid model; Probabilistic; Non-probabilistic reliability; Ellipsoid-bound convex model

Imprecise Probabilities in Engineering Analyses
Probabilistic uncertainty and imprecision in structural parameters and in environmental conditions and loads are challenging phenomena in engineering analyses. They require appropriate mathematical modeling and quanti cation to obtain realistic results when predicting the behavior and reliability of engineering structures and systems. But the modeling and quanti cation is complicated by the cha...
متن کاملStructural Reliability Assessment with Fuzzy Probabilities
The prediction of the behavior and reliability of engineering structures and systems is often plagued by uncertainty and imprecision caused by sparse data, poor measurements and linguistic information. Accounting for such limitations complicates the mathematical modeling required to obtain realistic results in engineering analyses. The framework of imprecise probabilities provides a mathematica...
متن کاملThe Effect of Tuned Mass Damper on Seismic Response of Building Frames with Uncertain Structural Characteristics
Tuned mass dampers (TMDs) could be used to absorb the input energy of the applied load, and reduce the response of the building frames. However, the effectiveness of TMD in reducing the response of the building frames could be affected by inherited uncertainties in the structural characteristics of the frames. In this study, in order to investigate the probabilistic response of steel moment-res...
متن کاملA fuzzy production model with probabilistic resalable returns
In this paper, a fuzzy production inventory model with resalable returns has been analysed in an imprecise and uncertain environment by considering the cost and revenue parameters as trapezoidal fuzzy numbers. The main objective is to determine the optimal fuzzy production lotsize which maximizes the expected profit where the products leftout at the end of the period are salvaged and demands wh...

For structural reliability assessment or risk analysis of aging offshore steel structures, it is essential to have a probabilistic model, which contains specific statistical parameters, and predicts long term corrosion loss as a function of time. The aim of this study is to propose such model for offshore jacket platforms in the Persian Gulf. Field measurements for material loss due to uniform ...
