1. 1. FE-Modelling of Composite Girder tests

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Holger Berggren; Bergstedt Ola; [2024]
   Keywords : shear connector; post-installed; coiled spring pins; composite girder; partial composite action; finite element method;

   Abstract : Many of the existing steel-concrete bridges may need to be strengthened, as heavier vehicles areallowed on the Swedish roads. These bridges could possibly be strengthened by post-installingshear connectors. The shear connectors may enhance the load-bearing capacity through a higherdegree of composite action between the steel and concrete interface. READ MORE

3. 2. FE-modelling of glulam connection in a pre-tensioned glulam truss : Detailed Finite element modelling of the connection between primary beam and compression stud in a sub-tensioned glulam roof truss

   University essay from KTH/Bro- och stålbyggnad

   Author : Edward Sebastian Swaretz; [2022]
   Keywords : Glulam; sub-tensioned roof truss; connection; instability; Abaqus Standard; Finite element method;

   Abstract : After the collapse of the roof structure in Tarfalahallen 2020, great attention has been focused on instability of sub-tensioned glulam roof trusses. Investigations were launched to find the reason for the collapse and the cause was instability in the roof truss that supported the roof. READ MORE

4. 3. EVALUATION OF ENVIRONMENTAL AND TECHNICAL PERFORMANCE OF ALTERNATE FIBRES FOR SHOTCRETE IN TUNNELS

   University essay from KTH/Betongbyggnad

   Author : Shilpa Anand; [2022]
   Keywords : Shotcrete; Life cycle assessment; Environmental Product Declaration; Global warming potential; steel; basalt and synthetic fibres; flexural strength; energy absorption.;

   Abstract : Tunnels in hard and jointed rock are normally excavated in an arch shape to enable the rock mass to support its weight. Since the beginning of the 1980's, fibre reinforced shotcrete (FRS) in combination with rock bolts have been the dominating support method for hard rock tunnels. READ MORE

5. 4. Evaluation of a testing method for shear stiffness properties for cross laminated timber

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

   Author : Calle Lind; [2022]
   Keywords : CLT; cross laminated timber; EN 16351; four-point bending; rolling shear modulus; FE-modelling; Technology and Engineering;

   Abstract : Cross laminated timber (CLT) is an engineered wood product that was first developed in the 1990s. Since then it has grown in popularity thanks to its many advantages such as: low environment impact, high degree of prefabrication and low weight. As the material is relatively new the standardization process is still in the early stages. READ MORE

6. 5. Linear Impact of Bicycle Helmet – Experimental Testing and FE-modelling

   University essay from KTH/Hållfasthetslära

   Author : Ludvig Dahlin; Ebba Larsson Regnström; [2022]
   Keywords : FEM; Finite element method; bicycle helmet; impact modelling; solid mechanics; FEM; Finita element-metoden; cykelhjälm; islagsmodellering; hållfasthetslära;

   Abstract : The aim with this master thesis was to set up a FE-simulation of an impact test of a bike helmet in LS-DYNA that correlates well with the peak acceleration score of a real life impact test. Furthermore, a parametric study has been performed in LS DYNA to investigate the robustness of the model, as well as to see which parameters have a great influence on the peak acceleration score.
