1. 1. 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

3. 2. Strengthening of non-composite bridges by Partial Composite Action

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

   Author : Johan Tjernberg; [2022]
   Keywords : Composite action; Composite bridges; Partial shear connection; Partial Composite Action; Shear connectors; Coiled Spring Pins;

   Abstract : A common bridge type is the steel-concrete bridge where the concrete deck is built over steel girders. In many earlier designs the bridge type was often built as non-composite, which means that the concrete deck and the steel girder has no shear connection at the steel-concrete interface and therefore bend as individual components.

4. 3. Non-Linear strain paths in Sheet Metal Forming

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Anton Eriksson; [2021]
   Keywords : Sheet metal forming SMF ; Non-Linear strain path NLSP ; Test procedures; Failure models; Finite Element FE ; Plåtformning; Icke-linjära töjningsbanor; Test procedurer; brott model; Finita Element FE .;

   Abstract : Today's automotive requirements have resulted in complex Sheet Metal Forming (SMF) processes of Sheet Metal (SM) with reduced formability, and thus it is crucial to be able to predict formability accurately to prevent material failure during SMF. Formability predictions today utilize Forming Limit Curves (FLC)s in Finite Element Analysis (FEA), but  FLCs are not valid for the Non-Linear Strain Paths (NLSP)s generated during SMF. READ MORE

5. 4. Influence of load distribution on trough bridges

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

   Author : Jacob Gustafsson; [2021]
   Keywords : Bridge; Trough bridge; Concrete; Load distribution; Ballast;

   Abstract : There are approximately 4000 railway bridges in Sweden and a common construction type is the short span concrete trough bridge. With the current standards the load distribution through ballast is assumed to be uniformly distributed with a distribution slope of 2:1 according to the Swedish Administration of Transport or 4:1 according to Eurocode 1.

6. 5. Concrete reinforced with FRP rebars : Evaluation of durability and behaviour in the Service Limit State (SLS)

   University essay from Luleå tekniska universitet/Byggkonstruktion och brand

   Author : David Ottosson; [2021]
   Keywords : GFRP; Durability; SLS; Atena;

   Abstract : One of the most common building materials is concrete and it has been for a long time. To overcome its low tensile capacity concrete structures are normally reinforced with steel rebars. READ MORE
