1. 1. Reinforced Concrete Subjected To Restraint Forces : A comparison with non-linear numerical analyses

   Master-uppsats, KTH/Bro- och stålbyggnad

   Författare :Niels Brattström; Oliver Hagman; [2017]
   Nyckelord :Restraint forces; concrete; cracking; restraint degree; crack width; creep; thermal actions; shrinkage; Tvångskrafter; betong; sprickor; inspänningsgrad; sprickvidder; krypning; termisk last; krympning;

   Sammanfattning : In Sweden, it is Eurocode 2 which forms the basis for performing a design of concrete structures, in which methods can be found treating the subject of restrained concrete members and cracking in the serviceability limit state. In the code, both detailed hand calculations procedures as well as simplified methods are described. LÄS MER

3. 2. Redistribution of bending moments in concrete slabs in the SLS

   Master-uppsats, KTH/Bro- och stålbyggnad

   Författare :Einar Óskarsson; [2014]
   Nyckelord :Finite element analysis; reinforced concrete; concrete slab; non-linear analysis; crack control; fracture energy;

   Sammanfattning : The finite element method (FEM) is commonly used to design the reinforcement in concrete slabs. In order to simplify the analysis and to be able to utilize the superposition principle for evaluating the effect of load combinations, a linear analysis is generally adopted although concrete slabs normally have a pronounced non-linear response.
