1. 1. Shear Failure of Steel Fiber and Bar Reinforced Concrete Beams Without Stirrups : Predictions based on Nonlinear Finite Element Analyses

   University essay from KTH/Betongbyggnad

   Author : David Andersson; [2022]
   Keywords : Nonlinear finite element analysis; Shear failure; Fiber reinforced concrete beams; ATENA;

   Abstract : Shear failure in concrete beams are often brittle in nature and potentially dangerous without adequatereinforcing measures. In design of concrete, it is commonly recommended to install transversalreinforcement along the shear span to induce a more ductile structural response, improving the shearcapacity all together and providing sufficient warning prior to collapse.

3. 2. 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.

4. 3. Stability of building structures using NLFEA including second order effects : Applications with the software ATENA-GiD

   University essay from KTH/Betongbyggnad

   Author : Alexandros Petkoglou; [2021]
   Keywords : Non-linear analysis; second order effects; prefabricated buildings; ATENA; GiD; slip connection; Icke-linjär analys; andra ordnings effekter; förtillverkade byggnader; prefabricerade byggnader; ATENA; GiD; glidkoppling;

   Abstract : In Sweden, prefabrication in the construction industry is a very common system. In prefabricated structures, there are various kinds of connections and generally many hinged connections. Therefore, it is of high interest to study the behavior of the prefabricated buildings in relation to the connections. READ MORE

5. 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 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

6. 5. RC Trough Bridges: A Parametric Study using FEM and an Analysis of their Current State

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

   Author : David Åkergren; [2021]
   Keywords : concrete; trough bridges; parametric study; FEM; BaTMan; ATENA; load eccentricity; compressive strength; tensile strength;

   Abstract : There are approximately 4000 railway bridges in Sweden managed by the Swedish Administration of Transport (Trafikverket), of which a common construction type is the reinforced concrete (RC) trough bridge, which is a structure that consists of a slab carried by two longitudinal main beams which transfer loads towards the supports. A substantial amount of the RC trough bridge population is approaching the end of their service lives which consequently implies that the replacement of some of these bridges can be expected in the near future.
