Processing uncertainty in structural analysis, design and safety assessment

چکیده
In this paper a fuzzy method for determining appropriate structural design is presented. Non-stochastic uncertainty is quantified using fuzzy values and fuzzy random variables. Fuzzy structural parameters are processed on the basis of a generally applicable numerical method for arbitrary nonlinear fuzzy structural analyses. Fuzzy randomness is introduced into a fuzzy probabilistic safety assessment. This leads to fuzzy results representing fuzzy structural responses and fuzzy safety levels. Referring to permissible structural responses and safety levels uncertain structural design parameters are derived. The nonlinear fuzzy structural analysis including uncertain structural design is demonstrated by way of an example.

Probabilistic Assessment of Pseudo-Static Design of Gravity-Type Quay Walls
Failure of the quay walls due to earthquakes results in severe economic loss. Because of hazards threatening such inexpensive nodes of national and international transportation networks, seismic design of quay walls is still an evolving topic in marine structural engineering. This study investigates the sensitivity of the gravity-type quay wall stability respect to uncertain soil and seismic pr...
متن کاملUNCERTAINTY ANALYSIS OF STABILITY OF GRAVITY DAMS USING THE FUZZY SET THEORY
This paper introduces a methodology for considering the uncertainties in stability analysis of gravity dams. For this purpose, a conceptual model based on the fuzzy set theory and Genetic Algorithm (GA) optimization is developed to be coupled to a gravity dam analysis model. The uncertainties are represented by the fuzzy numbers and the GA is used to estimate in what...
متن کاملDynamical stability of cantilevered pipe conveying fluid in the presence of linear dynamic vibration absorber
When the velocity of fluid flow in a cantilevered pipe is successively increased, the system may become unstable and flutter instability would occur at a critical flow velocity. This paper is concerned with exploring the dynamical stability of a cantilevered fluid-conveying pipe with an additional linear dynamic vibration absorber (DVA) attachment. It is endeavoured to show that the stability o...
متن کاملTackling uncertainty in safety risk analysis in process systems: The case of gas pressure reduction stations
Industrial plants are subjected to very dangerous events. Therefore, it is very essential to carry out an efficient risk and safety analysis. In classical applications, risk analysis treats event probabilities as certain data, while there is much penurious knowledge and uncertainty in generic failure data that will lead to biased and inconsistent alternative estimates. Then, in order to achieve...
متن کاملDynamic Mediation for Removing Language Comprehension Problems: A Psychological Support for Listening Comprehension Mental Processing
Dynamic Assessment is an approach to assessment within Applied Linguistics which is stemmed from Vygotsky’s Socio-Cultural Theory of mind, his concept of Zone of Proximal Development and Feuerstein's theory of Structural Cognitive Modifiability. This study is an attempt to pinpoint the sources of mental processing problems in listening comprehension and applies dynamic interventions to remove t...
