  3. 3. Load Bearing Capacity and Behaviour of Composite Slabs with Profiled Steel Sheet

    Författare :Li An; Chalmers University of Technology; []
    Nyckelord :load bearing capacity; composite slabs; shear resistance; concrete;

    Sammanfattning : In many cases the capacity of composite slabs with profiled steel sheeting depends on the shear resistance at the sheet-concrete interface. This shear resistance is essential to the interaction between the steel sheeting and the concrete. Besides this, other factors also affect the behaviour of composite slabs. LÄS MER

  4. 4. Creating an environmental sustainability profession

    Författare :Stina Månsson; Chalmers University of Technology; []
    Nyckelord :SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SOCIAL SCIENCES; Environmental sustainability; practice; environmental managers; AEC industry.; hybrid institutional logics; environmental sustainability professionals; professionalisation processes;

    Sammanfattning : The purpose of this thesis it to problematize the professionalization processes of environmental sustainability roles by studying how professionals in the Swedish AEC industry actively participate in the continuous creation of an environmental sustainability profession. This is done by investigating how the role of environmental sustainability professionals, as carriers and executers of an environmental sustainability agenda, has developed since the early 1990s, and how they are maintaining a momentum for environmental sustainability practice.
