  1. 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.

  2. 2. Assessment of prestressed concrete bridges loaded in combined shear, torsion and bending : uncertaintiers in deterministic and statistic methods

    Author : Arto Puurula; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : The aim of the thesis is to investigate the load-carrying capacity of bridges according to different models for shear in combination with bending, torsion and prestressing. The following models are studied: Model with traditional summation of the contributions from concrete and steel accroding to the Swedish Code BBK 94 Strut model according to the European code EC2 Modified Compression Field Theory from Canada The models are applied to the Källösund Bridge on the road to the island Tjörn on the West coast of Sweden.
