  3. 3. Methods for reliability based design optimization of structural components

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Tomas Dersjö; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability;

    Abstract : Cost and quality are key properties of a product, possibly even the two most important. Onedefinition of quality is fitness for purpose. Load-bearing products, i.e. READ MORE

  4. 4. Reliability-based Assessment of Concrete Dam Stability

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Marie Westberg; Lunds universitet.; Lund University.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; assessment; stability; concrete dam; structural reliability analysis; probability; uplift; system reliability;

    Abstract : Risk management is increasingly used in dam safety and includes risk analysis, risk evaluation and risk reduction. Structural Reliability Analysis (SRA) is a probabilistic methodology that may be used in the risk assessment process. READ MORE

  5. 5. Fatigue evaluation of welded details – using the finite element method

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Mustafa Aygül; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; the finite element method; welded details; effective notch stress method; Hot-spot stress method; fracture mechanics;

    Abstract : The fatigue evaluation of welded details is generally based on the notion of nominal stress, using the classified S-N curves with corresponding fatigue classes for typical details. An approach of this kind should be used with extra caution to ensure that the load effects for components are accurately captured, because an ever-increasing number of welded details are resulting in a limited number of possible treatable design cases.
