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. Shear and Torsion in Concrete Structures Non-linear Finte Element Analysis in Design and Assessment

   Author : Helén Broo; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; torsion; box-girder bridge; hollow core unit; hollow core floor; non-linear finite element analysis.; shear; prestressed concrete; Reinforced concrete;

   Abstract : For structural design and assessment of reinforced concrete members, non-linear finite element analysis has become an important tool. However, design and assessment of shear and torsion are still done with simplified analytical or empirical design methods. READ MORE
