  1. 1. Numerical simulations of shear reinforced concrete beams subjected to blast loads

    University essay from KTH/Betongbyggnad

    Author : Anton Frank; Andreas Fristedt; [2021]
    Keywords : Numerical simulations; shear reinforcement; blast loads; dynamic shear failure; Numeriska simuleringar; tvärkraftsarmering; luftstötvåg; dynamiskt skjuvbrott;

    Abstract : Historical accidents and experimental investigations have made apparent that blast loaded concrete members are prone to fail in brittle shear rather than a ductile flexure mode. Air blasts from accidental detonations or explosives may cause severe damage to buildings and infrastructure and it is of great importance that load carrying members can withstand the impulse that arise to avoid progressive collapses.

  3. 2. Shear strength of prestressed concrete beams without shear reinforcement : A comparison between equations

    University essay from KTH/Betongbyggnad

    Author : Bawan Azad; [2021]
    Keywords : Shear force; prestress concrete; design provisions; Eurocode; carrying capacity; parametric study; concrete beam; Tvärkraft; förspänd betong; dimensioneringsbestämmelser; Eurokod; bärförmåga; parameterstudie; betongbalk;

    Abstract : A new version of EN 1992-1-1, Eurocode 2 for Design of Concrete Structures, is under development and one of the most discussed topics is shear capacity for prestressed concrete beams without shear reinforcement, partly because shear failure occurs suddenly and can have catastrophic consequences. For the new version of Eurocode, there are a total of three proposed equations to replace the two equations that currently exist in EN 1992-1-1 for shear capacity of prestressed concrete beams without shear reinforcement.

  4. 3. Concrete girders or steel trusses constituting the foundation under a building? : A comparison regarding the block Forskaren in Stockholm

    University essay from KTH/Byggteknik och design

    Author : Berta Moshye; Nancy Shlimon; [2020]
    Keywords : LCA; Concrete girders; Steel trusses; LCA; Betongbalkar; Stålfackverk;

    Abstract : Hagastaden is a new district in Stockholm that is growing, and many structures are being built. Kv Forskaren, a funnel-like office building, will be built above the Haga tunnel in an ongoing project. READ MORE

  5. 4. The effect of reinforcement configuration on crack widths in concrete deep beams

    University essay from KTH/Betongbyggnad

    Author : Rahimeh Hosseini; Anita Nolsjö; [2017]
    Keywords : crack widths; crack development; conventional beams; deep beams; reinforcement stress; tenslie- and crack reinforcement; minimum reinforcement; reinforcement configuration; external loads; non-linear analysis; sprickvidder; ordinära balkar; höga balkar; armeringsspänning; kraft- och sprickarmering; minimiarmering; armeringsutformning; externa laster; icke linär analys;

    Abstract : Reinforced concrete deep beams are known for applications in tall buildings, foundations and offshore structures. Deep beams are structural elements with length and height within the same magnitude and have significantly smaller thickness compared to a conventional concrete beam. READ MORE

  6. 5. Design of Thick Concrete Beams : Using Non-Linear FEM

    University essay from KTH/Bro- och stålbyggnad

    Author : Daniel Mekonnen Teklemariam; Bennie Hamunzala; [2016]
    Keywords : Thick concrete beam; Capacity; Non-linear finite element analysis; Crack width; Load deformation response; Ultimate and Serviceability limit state.; Tjocka betongbalkar; Kapacitet; Icke-linjära finita element analys; Sprikvidd; Deformation; Brott-och bruksgränstillstånd;

    Abstract : The experimental studies performed on the behaviour of very thick concrete beams subjected to static loads have revealed that the shear mechanisms play an important role in the overall response and failure behaviour. The aim of this thesis is to recommend suitable design methods for thick concrete beams subjected to off-centre static concentrated load according Eurocode 2 by using non-linear finite element analysis (NLFEA).
