  1. 1. Reducing Radon Gas Emissions in Concrete

    Author : Magnus Döse; Johan Silfwerbrand; Franz Josef Maringer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radon gas; emissions; health; concrete; building materials; ionizing radiation; Betongbyggnad; Concrete Structures;

    Abstract : Several compulsory regulations and recommendations regarding ionising radiation for building products have been introduced in recent years. Furthermore, industry-affiliated aggregate and concrete companies strive to implement environmental goals that should be fulfilled regarding building materials. READ MORE

  2. 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

  3. 3. Composite Action and Confinement Effects in Tubular Steel-Concrete Columns

    Author : Mathias Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; connection; composite action; composite column; finite element analysis; bond; confined concrete; high-strength concrete; experiment; concrete-filled steel tube;

    Abstract : Composite columns composed of concrete-filled steel tubes (CFT) have become increasingly popular in structural applications around the world. This type of column can offer many advantages, for instance, high strength, ductility, and large energy absorption capacity, as well as increased speed of construction, positive safety aspects, and possible use of simple standardized connections.

  4. 4. Secondary Emissions from Concrete Floors with Bonded Flooring Materials - Effects of Alkaline Hydrolysis and Stored Decomposition Products

    Author : Anders Sjöberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VOC; floorings; decomposition products; concrete; secondary emission; OCIC; moisture; IAQ; adhesive; building materials;

    Abstract : It has been demonstrated before that the presence of VOC lowers the quality of indoor air. There are also several indications that certain organic compounds in indoor air (OCIA) can give rise to sick building syndrome (SBS). READ MORE

  5. 5. Industrial Fibre Concrete Floors : Experiences and Tests on Pile-Supported Slab

    Author : Jerry Hedebratt; Johan Silfwerbrand; Terje Kanstad; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Pile supported floor slabs have often been designed solely in ultimate limit state ULS and then foremost with uniformly distributed loadings UDL. The investigation of serviceability limit state SLS has been of simpler nature, even according to the governing codes of practice. READ MORE
