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 stålbyggnadAbstract : 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

2. Non-Linear strain paths in Sheet Metal Forming
University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknikAbstract : 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

3. Influence of load distribution on trough bridges
University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserAbstract : 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.

4. Concrete reinforced with FRP rebars : Evaluation of durability and behaviour in the Service Limit State (SLS)
University essay from Luleå tekniska universitet/Byggkonstruktion och brandAbstract : 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

5. Numerical simulations of shear reinforced concrete beams subjected to blast loads
University essay from KTH/BetongbyggnadAbstract : Historical accidents and experimental investigations have made apparent that blast loaded concrete members are prone to fail in brittle shear rather than a ductile flexure mode. Air blasts from accidental detonations or explosives may cause severe damage to buildings and infrastructure and it is of great importance that load carrying members can withstand the impulse that arise to avoid progressive collapses.
