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

   Författare :Li An; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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
