1. 1. Soil Steel Composite Bridges for High-Speed Railways : 2D FEM analysis of the Björnbo Bridge

   University essay from KTH/Bro- och stålbyggnad

   Author : Joakim Woll; [2014]
   Keywords : Soil-Steel Composite Bridge; SSCB; Dynamic analysis; Björnbo Bridge; High-speed railways; FEM; Soil-Steel culvert; High-Speed Railway Soil-Steel Composite Bridge; Rörbro; Dynamisk analys; Björnbo rörbro; Höghastighetståg; FEM; Höghastighetståg rörbro; Dynamisk analys rörbro;

   Abstract : This research aims to analyse the dynamic behaviour of Soil-Steel Composite Bridges when subjected by high-speed trains. the analyses of the dynamic response for these structures are needed since there is little research performed in the present field of knowledge. READ MORE

3. 2. Dynamic analysis of soil-steel composite railway bridges : FE-modeling in Plaxis

   University essay from KTH/Bro- och stålbyggnad

   Author : Orod Aagah; Siavash Aryannejad; [2014]
   Keywords : Soil-steel composite bridge; Corrugated steel culvert; High-speed railways; FEM; Plaxis; Field measurements;

   Abstract : A soil-steel composite bridge is a structure comprised of corrugated steel plates, which are joined with bolted connections, enclosed in friction soil material on both sides and on the top. The surrounding friction soil material, or backfill, is applied in sequential steps, each step involving compaction of the soil, which is a necessity for the construction to accumulate the required bearing capacity.

4. 3. Uppfattningen om perenna gravplanteringar hos tre uppländska kyrkogårdsförvaltningar : en fallstudie

   University essay from SLU/Dept. of Urban and Rural Development

   Author : Hanna Johansson; [2013]
   Keywords : Hållbarhet; Kyrkogård; Perenner; Skötsel; Sommarblommor;

   Abstract : Perenner är på modet och har fått en större roll i planteringar i de offentliga rummen. Deras ekologiska och ekonomiska hållbarhet är god medan sommarblommor är både dyra och mindre bra för miljön. Det har lett till att trädgårdsexperter och forskare föreslår att sommarblommor på just kyrkogårdar ska bytas ut mot perenner. READ MORE

5. 4. Dynamic analysis of soil-steel composite bridges for high speed railway traffic : Case study of a bridge in Märsta, using field measurements and FE-analysis

   University essay from KTH/Bro- och stålbyggnad

   Author : Peyman Mellat; [2012]
   Keywords : Soil-Steel Composite Bridge; Flexible Corrugated Steel Culvert; Structural Dynamics; Acceleration; High-Speed Trains; Field Measurement; FEM;

   Abstract : Soil-steel composite bridge refers to structures where a buried flexible corrugated steel pipe works in composite action with the surrounding soil. These structures are being increasingly used in road and railway projects as an alternative to standard type bridges, e.g. short- and medium span concrete beam- and portal frame bridges. READ MORE

6. 5. Strategies for co-operated wood chip fired and municipal waste fired combined heat and power plants

   University essay from KTH/Kraft- och värmeteknologi

   Author : Alexander Taylor; [2012]
   Keywords : CHP; combined heat and power; co-operated power plants; municipal waste; wood chips; operational strategy; MATLAB;

   Abstract : The Brista 1 plant is a wood chip-fired combined heat and power (CHP) plant located near Märsta, northwest of Stockholm, Sweden. The primary purpose of the plant is to supply heat to the northwest district heating grid. In order to meet increasing demand for district heating, Fortum Heat is constructing a second CHP plant next to Brista 1. READ MORE
