1. Shear and Torsion Interaction in Prestressed Hollow Core Slabs
Sammanfattning : 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. Shear and Torsion in Concrete Structures Non-linear Finte Element Analysis in Design and Assessment
Sammanfattning : 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. LÄS MER
3. Experimental and Numerical Analyses of the Dynamic Behaviour of Hollow-Core Concrete Floors
Sammanfattning : 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. LÄS MER
