2. 1. Shear and Torsion Interaction in Prestressed Hollow Core Slabs

   Author : Helén Broo; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shear-torsion capacity; hollow core unit; shear and torsion interaction; non-linear finite element analyses; hollow core slab; precast prestressed concrete; hollow core floor;

   Abstract : There are many applications in which hollow core units are subjected to combined torsion and shear, for example in floors supported on three edges and in floors with openings. The traditional calculation method for combined shear and torsion in hollow-core units adds stresses from various sources without taking into account deformations and compatibility within the unit or restraint at the boundaries.

4. 2. Experimental and Numerical Analyses of the Dynamic Behaviour of Hollow-Core Concrete Floors

   Author : Fangzhou Liu; Jean-Marc Battini; Costin Pacoste; Bassam Izzuddin; KTH; []

   Abstract : Precast hollow-core (HC) concrete slabs are widely used in construction, especially in Nordic countries. The combination of prestressing and low self-weight due to the voids makes it possible to build long-span floors. However, this also implies that the HC concrete floors become more sensitive to vibrations from human activities. READ MORE
