  1. 1. Aspects on probabilistic approach to design : From uncertainties in pre-investigation to final design

    Författare :Anders Prästings; Stefan Larsson; Rasmus Müller; Jan Laue; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability-based design; Geotechnical design; Geotechnical structures; Sheet-pile wall; Characterization of uncertainties; Geotechnical investigations;

    Sammanfattning : Geotechnical engineering is strongly associated with large uncertainties. Exploring a medium (soil) that is almost entirely and completely hidden from us is no easy task. Investigations can be made only at discrete points, and the majority of a specific soil volume is never tested. LÄS MER

  3. 2. Design for Serviceability - A probabilistic approach

    Författare :Daniel Honfi; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design codes; long-term deflections; structural reliability; serviceability;

    Sammanfattning : In many design situations the acceptable performance of structures is defined by serviceability requirements. To estimate the probability of serviceability failure three main design aspects should be considered: (1) the relevant exposures, (2) the structural response and (3) the performance criteria.

  4. 3. Preliminaries for probabilistic railway sleeper design

    Författare :Johanna Lilja; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensor placement; factorial design; Railway sleeper; ballast; load variation; stochastic parameters; correlation length;

    Sammanfattning : Two investigations are presented, which can be seen ascontributions to the aim of introducing a probabilistic designstrategy of railway sleepers in the future. When usingprobabilistic design the statistics of all relevant parametersconsidered as stochastic must be known. LÄS MER

  5. 4. The strength of glulam beams with holes - A probabilistic fracture mechanics method and experimental tests

    Författare :Henrik Danielsson; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fracture mechanics; Weibull; design; test; strength; stress; glulam; hole; probabilistic fracture mechanics.;

    Sammanfattning : This thesis deals with experimental tests and methods for strength analysis of glulam beams with holes. Test results and methods for strength analysis available in literature are compiled and discussed. The methods considered comprise both code strength design methods and more general methods for strength analysis. LÄS MER

  7. 5. Draw control strategy for sublevel caving mines : A probabilistic approach

    Författare :Gurmeet Shekhar; Håkan Schunnesson; Anna Gustafson; Jesper Martinsson; Matthias Wimmer; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Draw control; sublevel caving; probability models; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Sammanfattning : Sublevel caving is an underground mass mining method used for extracting different types of ores from the earth crust. Mines using sublevel caving (SLC) as the primary mining method are generally highly mechanized with standardized and independent unit operations. LÄS MER
