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. Reduced stress method for steel in class 4 cross-sections : Evaluation of the reduced stress method for a railway bridge

   University essay from KTH/Byggteknik och design

   Author : Therese Badrous; Ebba Lund; [2021]
   Keywords : FEM; Reduced stress method; Effective cross-section method; Local buckling; Steel cross-section; Class 4 cross-section; Railway bridge; FEM; Reducerad spänningsmetoden; Effektivt tvärsnittsmetoden; Lokal buckling; Ståltvärsnitt; Tvärsnittklass 4; Järnvägsbro;

   Abstract : The effective cross-section method, also called reduced cross-section method is generally used for steel in class 4 cross-sections in considering local buckling. This method is a bit complicated and time consuming, which often leads to engineers not using profiles in class 4 cross-sections. READ MORE

4. 3. Modelling cross-laminated timber floors in dynamic analysis - Eigenfrequency prediction

   University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

   Author : Johannes Wetterholt; [2019]
   Keywords : finite element method; FEM; dynamic analysis; Eigenfrequency; CLT; cross-laminated timber; cross-laminated timber floors; wooden floors; Technology and Engineering;

   Abstract : In the late 1990s cross-laminated timber (CLT) was developed. The development of CLT was a project aimed to produce a structural product that could compete with the concrete industry and contribute to a reduced effect on the environment, due to the low environmental impact of timber in relation to other building materials.

5. 4. Patch loading resistance of welded I-beams : with respect to misaligned web stiffeners

   University essay from KTH/Stålbyggnad

   Author : John-Alexander Boutzas; Dafina Zeka; [2016]
   Keywords : Patch loading; Stiffeners; I-beam; Plated steel structures; Abaqus; Simply supported beam;

   Abstract : When a concentrated load is introduced perpendicular to the flanges of a steel beam, this condition is referred to as Patch loading (Gozzi, 2007). This occurrence is common in many steel structures, for example at supports or during launching of bridges. READ MORE

6. 5. Comparison of ballasted and ballastless bridges for high speed trains

   University essay from KTH/Bro- och stålbyggnad

   Author : David Matos Sánchez; Maša Nikolic; [2016]
   Keywords : High-speed train; concrete bridge; beam bridge; dynamic; 3D dynamic;

   Abstract : The purpose of the project is to investigate the difference in performance between ballasted and ballastless railway bridges dedicated to high speed trains by taking into account both static and dynamic requirements. The main questions are: a) whether choosing a ballastless bridge results in a more slender section due to the lower self-weight b) if the design of bridges for high speed trains is governed by the static or by the dynamic requirements.
