  2. 1. Shear walls with double plasterboards : evalutation of design models

    Author : Tomas Filipsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : This thesis presents a part of the ECSC-project Development of dry composite construction systems based on steel in residential application that focus on design recommendations for stabilizing buildings by using shear resistance in the walls. The existing design method suggested and used by the Swedish plasterboard manufacturer Gyproc AB is considered as a bit conservative and it does not consider double plasterboards properly. READ MORE

  4. 2. Modeling of Initial Mold Filling in Uphill Teeming Process Considering a Trumpet

    Author : Zhe Tan; Pär Jönsson; Robert Eriksson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gating system; uphill teeming; ingot casting; swirl blade; flow pattern; realizable k-ε model; CFD; mathematical modeling.;

    Abstract : The flow pattern in the uphill teeming process has been found to be closely related to the quality of ingots and further to affect the yield of ingot production, which is crucial for the steel making process. The formation of non-metallic inclusion and entrapment of mold flux has been considered to be affected by the flow pattern in the gating system and molds by many previous researchers. READ MORE

  5. 3. Stabilising system for multi-storey beam and post timber buildings

    Author : Gabriela Tlustochowicz; André J.M. Jorissen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Abstract : For multi-storey timber buildings, the stabilisation against horizontal loads is one of the key issues, which becomes more severe with height. There are a few main concepts utilised to resist lateral forces; shear wall action, diagonal bracing, and frame action. READ MORE

  6. 4. A Study of the Swirling Flow Pattern when Using TurboSwirl in the Casting Process

    Author : Haitong Bai; Mikael Ersson; Pär Jönsson; Yogeshwar Sahai; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow pattern; swirling flow; TurboSwirl; CFD; turbulence models; water model; flödesmönster; roterandeflöde; TurboSwirl; CFD; turbulensmodeller; vattenmodell; Metallurgical process science; Metallurgisk processvetenskap;

    Abstract : The use of a swirling flow can provide a more uniform velocity distribution and a calmer filling condition according to previous studies of both ingot and continuous casting processes of steel. However, the existing swirling flow generation methods developed in last decades all have some limitations. READ MORE

  7. 5. FRCM-Composites for Strengthening Concrete Walls with Openings : Experimental and Numerical Analysis

    Author : Cristian Sabau; Björn Täljsten; Thomas Blanksvärd; Gabriel Sas; Cosmin Popescu; Thanasis C. Triantafillou; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FRCM; reinforced concrete; walls; openings; strenghtening; Structural Engineering; Konstruktionsteknik;

    Abstract : Upgrading existing buildings to new functional requirements may require new openings that can weaken the structure, prompting the need for strengthening. In such cases, traditional strengthening solutions, such as creating a reinforced concrete or steel frame around the opening, imply long-term restrictions in the use of the structure. READ MORE
