  3. 2. Strengthening of non-composite bridges by Partial Composite Action

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

    Author : Johan Tjernberg; [2022]
    Keywords : Composite action; Composite bridges; Partial shear connection; Partial Composite Action; Shear connectors; Coiled Spring Pins;

    Abstract : A common bridge type is the steel-concrete bridge where the concrete deck is built over steel girders. In many earlier designs the bridge type was often built as non-composite, which means that the concrete deck and the steel girder has no shear connection at the steel-concrete interface and therefore bend as individual components.

  6. 5. Optimization of Ground Source Cooling Combined with Free Cooling for Protected Sites

    University essay from KTH/Tillämpad termodynamik och kylteknik

    Author : Eric Johansson; [2012]
    Keywords : Cooling; Borehole; Ground Source; Free Cooling;

    Abstract : Ground source cooling is commonly used for cooling of electronics in protected sites. Sometimes the boreholes are combined with free cooling from the air using a dry cooler to reduce the amount and length of the boreholes, which is the biggest part of the costs. The dry cooler can have two different running modes. READ MORE
