  1. 6. Comparison of Punching Shear Design Provisions for Flat Slabs

    Master-uppsats, KTH/Betongbyggnad

    Författare :Jonatan Aalto; Elisabeth Neuman; [2017]
    Nyckelord :Punching shear; resistance; concrete; flat slab; design provisions; Eurocode 2; case study; parametric study; shear reinforcement; prestressed;

    Sammanfattning : Abstract A new generation of EN 1992-1-1 (2004) also known as Eurocode 2 is under development and currently there is a set of proposed provisions regarding section 6.4 about punching shear, PT1prEN 1992-1-1(2017). It was of interest to compare the proposal with the current punching shear design provisions. LÄS MER

  3. 7. Beräkning av skjuvbrott i pelarunderstödda plattor : En studie av kontrollen utanför påverkade zonen vid beräkning av genomstansning

    M1-uppsats, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Sebastian Nyberg; [2017]
    Nyckelord :Punching; Shear failure; Slabs supported on columns; Shear reinforcement; Eurocode 2; ACI318; BS8110; Genomstansning; Skjuvbrott; Pelardäck; Skjuvarmering; Eurokod 2; ACI318; BS8110;

    Sammanfattning : The calculation process in Eurocode 2 that is showing how calculation of punching is to be done is long and some parts are not well explained. At the end of the calculation of punching, it is said that a check of the shear capacity without any reinforcement should be done outside the affected zone but the intent of the check is not justified.

  4. 8. Non-Linear Assessment of a Concrete Bridge Slab Loaded to Failure

    Master-uppsats, KTH/Betongbyggnad

    Författare :Eriksson Isabell; Niklas Karlsson; [2016]
    Nyckelord :concrete; linear shear; punching shear; non-linear finite element analysis; Eurocode; Model Code; ATENA 3D; betong; skjuvning; genomstansning; icke-linjär finit-elementanalys; Eurocode; Model Code; ATENA 3D;

    Sammanfattning : This thesis covers an investigation regarding the failure in the bridge slab of Gruvvägsbron, which was the result of the full scale test that the bridge was subjected to prior to demolition. Using the non-linear finite element software ATENA 3D, a model of the bridge was assembled, with the purpose to attempt to reenact the test procedure and realistically capture the failure load and behaviour.

  5. 9. Jämförelsestudie för tre olika metoder att beräkna genomstansning i betong : Skillnader i genomstansningskapacitet för metoderna i BBK04, EK2 och BHB

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Byggteknik

    Författare :Björn Zetterström; [2014]
    Nyckelord :;

    Sammanfattning : Before the European construction standards were introduced in January 2011, it was mainly the method in BBK04 that was used for calculating punching capacity in concrete structures, and in less common cases the method in BHB. The method of BBK04 is easy to use and have had the same structure since the first was published in 1979. LÄS MER

  7. 10. Punching Shear Capacity of Fibre Reinforced Concrete Slabs with Conventional Reinforcement : Computational analysis of punching models

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Zeinab Tazaly; [2012]
    Nyckelord :Steel fibre reinforced concrete slab; punching capacity; concrete test; residual tensile strength; DAfStB; Swedish Concrete Association; conventional reinforcement;

    Sammanfattning : Steel fibre reinforced concrete is not a novel concept, it has been around since the mid-1900s, but despite its great success in shotcrete-reinforced rock walls and industrial floors it has not made any impact on either beams or elevated slab. Apparently, the absence of standards is the main reason. LÄS MER
