| Popis: | Different studies in recent years show that many structural failures are due to errors in planning, design, construction and utilization. These are difficult to quantify and have not been considered in probabilistic design methodologies (reliability theory). In practice the designer must use his practical experiences, the actual conditions and the pure speculations when evaluating safety factor values. Therefore, the reliability of structures is not only an objective but also a subjective concept, which is a property of the designer's state of knowledge. They need a way of combining all the subjective information, which are of multivalued nature and come from multiple sourcesof estimates. In this study an inferential method applying fuzzy set and fuzzy logic to analyze safety of the existing structures is presented. |
