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. An experimental study of the validity of the round panel test method for shotcrete

   University essay from KTH/Betongbyggnad

   Author : Nadia El zain; [2018]
   Keywords : Shotcrete; sprayed concrete; yield line theory; tunnel lining; steel fibers; round determinate panels; test beams; Sprutbetong; runda plattor; tunnelbeklädnad; fiberarmerad sprutbetong; stålfibrer; böjdraghållfasthet; balkar; mätosäkerhet;

   Abstract : Shotcrete (sprayed concrete) was used for the first time in 1914 and has become of  growing importance in stabilizing the excavated tunnel sections over the past century.  Even though the technology develops, there are some difficult tasks such as the design of a bolt anchored tunnel lining made of shotcrete.

4. 3. Widening of The Nockeby Bridge : Methods for strengthening the torsional resistance

   University essay from KTH/Bro- och stålbyggnad

   Author : Jenny Andersson; [2016]
   Keywords : Strengthening of bridges; external prestressed reinforcement; carbon-fiber reinforced polymer; torsion; torsional resistance; prestressed concrete; Förstärkning av broar; extern spännarmering; kolfiberförstärkning; vridning; vridkapacitet; förspänd betong;

   Abstract : i Abstract The Nockeby Bridge, in the western part of Stockholm, is a prestressed concrete bridge with an openable swing span of steel. The bridge was built during 1970 and should now be widened with 0.5 meters on each side. The concrete bridge deck is supported by two main-beams and cross-beams are located at the position of all supports. READ MORE

5. 4. Reinforced Concrete Beams Strengthened with Side Near Surface Mounted FRP : A parametric study based on finite element analysis

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

   Author : Rewan Eredini; [2016]
   Keywords : Side near surface mounted reinforcement; Bottom near surface mounted reinforcement; Parametric study; FEM-analysis; Atena; Carbon fiber reinforced polymer;

   Abstract : Most of the today’s concrete structures are older than tenyears, and the need to strengthening existing structures is growing steadily. This is due to various reasons such as degradation due to ageing, environmentally induced degradation, poor initial design or construction and lack of maintenance, to name a few. READ MORE

6. 5. 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
