1. 1. Harmonised traffic load model between Eurocode 1 - part 2 (EN 1991-2) and TRV specifications : A pilot study on reinforced concrete portal frame bridges

   University essay from KTH/Bro- och stålbyggnad

   Author : Mubashar Amir Ablahad; Nuredin Rasslan; [2023]
   Keywords : ;

   Abstract : The advancement of society has led to an increase in demand for infrastructure, particularly bridges, which are designed in accordance with different design codes. In Sweden, bridge design adheres to the Eurocode and national code (TRV specifications), with the most adverse scenario of the two codes determining the basis for bridge design. READ MORE

3. 2. Linear and non-linear FE-analysis of cracking behavior of wing walls in integral bridges

   University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

   Author : Andreas Ekman; Christoffer Sandin; [2018]
   Keywords : Non linear FE-modelling; Concrete Damage Plasticity; Wing wall; Crack propagation; Serviceability Limit State; Slab Frame Bridge; Technology and Engineering;

   Abstract : Wing walls on slab frame integral bridges has traditionally been designed for mainly earth pressure and its self-weight. It has also been designed separately from the rest of the bridge. Traditionally no 3D effects have been considered in the design of the wing walls. READ MORE

4. 3. Increased Traffic Loads on Swedish Highway Bridges : A Case study of the bridge at highway interchange Värö

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

   Author : Fredrik Forsberg; [2017]
   Keywords : BRIGADE Standard; Concrete slab frame bridge; FEM; Load carrying capacity calculation; Load carrying capacity class; BRIGADE Standard; Bärighetsberäkningar; Plattrambro; FEM; Bärighetsklasser;

   Abstract : The Swedish government is planning to increase the maximum vehicle gross load regulations on parts of the national roads from the present 60 t, for the load carrying capacity class BK1, to 74 t, for the proposed new load carrying capacity class BK4. The initial implementation of the new load carrying capacity class for 74 t vehicles will only regard major highways and important roads, however, at a later stage the plan is to implement the new BK4 class on the full current BK1 road network.

5. 4. Investigation of cracking due to restraint forces in Swedish concrete slab frame bridges

   University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

   Author : Robin Almen; [2016]
   Keywords : slab frame bridges; concrete cracking; crack control; restraint; restraint forces; finite element; Technology and Engineering;

   Abstract : When concrete slab frame bridges are designed with modern linear 3D FE-models large tensile restraint forces will arise in the transversal direction of the bridge from the temperature and shrinkage loads. These restraint forces are much larger than those that are accounted for in the older 2D models. READ MORE

6. 5. 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
