1. 1. Structural robustness - FE methodology for analysing alternate load paths in buildings

   University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

   Author : Axel Kjellman; [2017]
   Keywords : accidental action; robustness; finite element method; FE; dynamics; progressive collapse; redundancy; alternate path; notional removal; precast; Technology and Engineering;

   Abstract : Robust structures are necessary in order to avoid a progressive collapse if a local failure occurs, for instance, failure of a column. Robustness is achieved in structures by designing them for so-called accidental actions, such as an explosion or a vehicle impact. READ MORE

3. 2. Cracking Assessment of Concrete Slab Frame Bridges Exposed to Thermally Induced Restraint Forces

   University essay from KTH/Betongbyggnad

   Author : Jonatan Ledin; Christensen Oskar; [2015]
   Keywords : Concrete slab frame bridges; Restraint forces; Thermal actions; Non linear FE analysis;

   Abstract : The usage of linear 3D FEA is widespread within the bridge design community, and although this tool provides substantial benefits in the design process, there are certain practical issues related to the application of this analysis tool. A situation in which such an issue prevails is when linear 3D FEA is used to analyze restraint forces due to thermal shrinkage or expansion in concrete slab frame bridges. READ MORE
