  1. 1. Reliability-Based Sensitivity Analysis of the Dynamic Response of Railway Bridges

    University essay from KTH/Bro- och stålbyggnad

    Author : Hasan Al-Zubaidi; [2022]
    Keywords : Railway bridges; High-speed trains; Simply supported beam; Global sensitivity analysis; Uncertainty quantification; Reliability; Ballast instability; Running safety; Passenger comfort;

    Abstract : In response to the planned increase in operational speeds and axle loads of passengertrains that may lead to resonance-induced excessive vibrations in railway bridges,recent studies examined the reliability of bridges concerning train running safety andpassenger comfort limit states. In this respect, valuable information regarding theimportance of input variables can be obtained by conducting Sensitivity Analysis (SA). READ MORE

  3. 2. Reliability – based analysis of embankment dams

    University essay from KTH/Byggvetenskap

    Author : Xiaochen Liu; [2019]
    Keywords : Embankment dams; reliability-based analysis; slope stability analysis; internal erosion; dam safety; fyllningsdammar; tillförlitlighetsbaserad analys; analys av släntstabilitet; inre erosion; dammsäkerhet;

    Abstract : Embankment dams are widely used as water-retaining structures through the world. Two principal structural failure modes of embankment dams are internal erosion and slope instability. The objective of this thesis is to investigate the feasibility of applying probabilistic methods in embankment dam assessment. READ MORE

  5. 4. Reliability-Based Analysis of Concrete Dams

    University essay from KTH/Jord- och bergmekanik

    Author : David Fouhy; Francisco Ríos Bayona; [2014]
    Keywords : concrete dams; buttress dams; gravity dams; probabilistic analyses; stability analyses; sliding stability; overturning stability; rock bolts; persistent rock joint; dam safety;

    Abstract : Dams are designed and assessed based on traditional factor of safety methodology. Several drawbacks of this approach exist; for example varying failure probability for structures where the factor of safety is the same. This traditional factor of safety methodology imposes conservative assumptions in terms of both design and analysis. READ MORE

  6. 5. A Comprehensive Evaluation of Conversion Approaches for Different Function Points

    University essay from Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

    Author : Javad Mohammadian Amiri; Venkata Vinod Kumar Padmanabhuni; [2011]
    Keywords : Functional Size Measurement FSM ; Conversion; Systematic Literature Review; Regression Analysis;

    Abstract : Context: Software cost and effort estimation are important activities for planning and estimation of software projects. One major player for cost and effort estimation is functional size of software which can be measured in variety of methods. Having several methods for measuring one entity, converting outputs of these methods becomes important. READ MORE
