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

    Författare :Mathias Johansson; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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.

  5. 4. Composite Columns of Hollow Steel Sections Filled with High Strength Concrete

    Författare :Marianne Grauers; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In the design of buildings today, great effort is made to increase the structural flexibility. This has resulted in a demand for columns with reduced cross sections. To achieve a high load bearing capacity with a small cross sectional area, it is worthwhile to study the possibility of utilizing high strength concrete and composite effects. LÄS MER

  7. 5. Structural Analysis of Deep Composite Box-Type Components with application to a proprietary stabilising timber wall element

    Författare :Seyed Rasoul Atashipour; Per Johan Gustafsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Sammanfattning : The stabilising wall element of the Trä8-system is a deep box-type beam/column element which is made of different types of timber composites including framing members of gluedlaminated timber (glulam) and sheathings of laminated veneer lumber (LVL). This element is used as a ―shear wall‖ in multi-storey buildings up to four storeys. LÄS MER
