1. 16. 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

3. 17. Temperature analyses of Concrete Frame Bridges with Finite Elements

   University essay from KTH/Bro- och stålbyggnad

   Author : Siamak Rouhani; [2014]
   Keywords : Finite Element; modeling; thermal effects; concrete; frame bridge; sectional forces; reinforcement.;

   Abstract : FE-modeling is a rapidly spreading method to analyze structures nowadays. With this theunderstanding of the outcome is of very high importance and potential inaccuracies areimportant to find so that faulty and over dimensioning of the structure does not occur whichleads to unnecessary costs.

4. 18. Dynamic analysis of soil-steel composite railway bridges : FE-modeling in Plaxis

   University essay from KTH/Bro- och stålbyggnad

   Author : Orod Aagah; Siavash Aryannejad; [2014]
   Keywords : Soil-steel composite bridge; Corrugated steel culvert; High-speed railways; FEM; Plaxis; Field measurements;

   Abstract : A soil-steel composite bridge is a structure comprised of corrugated steel plates, which are joined with bolted connections, enclosed in friction soil material on both sides and on the top. The surrounding friction soil material, or backfill, is applied in sequential steps, each step involving compaction of the soil, which is a necessity for the construction to accumulate the required bearing capacity.

5. 19. FE modeling of bolted joints in structures

   University essay from Hållfasthetslära; Tekniska högskolan

   Author : Alexandra Korolija; [2012]
   Keywords : Bolted joints; Fastener joints; Load distribution; Flexibility; Connector element;

   Abstract : This paper presents the development of a finite element method for modeling fastener joints in aircraft structures. By using connector element in commercial software Abaqus, the finite element method can handle multi-bolt joints and secondary bending. The plates in the joints are modeled with shell elements or solid elements. READ MORE

6. 20. Numerical Evaluation of Structural Behavior of the Simply Supported FRP-RC Beams

   University essay from KTH/Betongbyggnad

   Author : Marjan Shahrokh Esfahani; Rasoul Nilforoush Hamedani; [2012]
   Keywords : ;

   Abstract : The main problem of steel-reinforced concrete structures is corrosion of steel reinforcements which leads to premature failure of the concrete structures. This problem costs a lot annually to rehabilitate and repair these structures. READ MORE
