  1. 1. A systems approach to ice loads on concrete dams

    Författare :Rikard Hellgren; Richard Malm; Anders Ansell; Erik Nordström; Pierre Legér; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ice loads; Ice pressure; Dam safety; Concrete dams; Cold regions; Monitoring; Measurements; Concrete Structures; Betongbyggnad;

    Sammanfattning : Dams are mainly used for the storage of water to electricity production and irrigation, or for river regulation. Continuous work to assure a high dam safety level is a prerequisite to minimize the risk for the uncontrolled release of water. LÄS MER

  3. 2. Analysis of Dynamic Flight Loads

    Författare :Natascha Jansson; Ulf Ringertz; David Eller; Peter Linde; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis deals with the determination of loads on an aircraft struc- ture during flight. The focus is on flight conditions where the loads are significantly time-dependent. Analysis of flight loads is primarily motivated to ensure that structural failure is avoided. LÄS MER

  4. 3. Critical loads - assessment of uncertainty

    Författare :Andreas Barkman; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; landscape planning; regionalisation; forestry; BC Al; sensitivity analysis; risk assessment; Monte Carlo simulation; PROFILE; critical level; exceedance; Acidification; forest soil; policy; EMEP; GIS.; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Sammanfattning : The effects of data uncertainty in applications of the critical loads concept were investigated on different spatial resolutions in Sweden and northern Czech Republic. Critical loads of acidity (CL) were calculated for Sweden using the biogeochemical model PROFILE. LÄS MER

  5. 4. Upgrading concrete bridges : post-tensioning for higher loads

    Författare :Jonny Nilimaa; Mohammad Al-Emrani; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete; Bridges; Upgrading; Strengthening; Shear; Field testing; Post-tensioning; Prestressing; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : There are a great number of old structures around the world, some of which were designed for completely different purposes than in their current application. Swedish railway bridges were for example only designed for maximum axle loads of 200 kN in the beginning of the 20th century, while the highest axle loads of today are twice as high. LÄS MER

  7. 5. Energy efficiency in shopping malls. Energy use and indoor climate

    Författare :Sofia Stensson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy use; loads; cooling; Shopping mall; simulation; heating; field measurements;

    Sammanfattning : The purpose of this licentiate thesis is to describe energy use, heating and cooling demands and the relative importance of internal heat loads in shopping malls. It will be a foundation for a future doctorial thesis in which alternative energy efficient HVAC systems for shopping malls will be analysed. LÄS MER
