  1. 1. FE-modelling of glulam connection in a pre-tensioned glulam truss : Detailed Finite element modelling of the connection between primary beam and compression stud in a sub-tensioned glulam roof truss

    University essay from KTH/Bro- och stålbyggnad

    Author : Edward Sebastian Swaretz; [2022]
    Keywords : Glulam; sub-tensioned roof truss; connection; instability; Abaqus Standard; Finite element method;

    Abstract : After the collapse of the roof structure in Tarfalahallen 2020, great attention has been focused on instability of sub-tensioned glulam roof trusses. Investigations were launched to find the reason for the collapse and the cause was instability in the roof truss that supported the roof. READ MORE

  3. 2. A parametric study of the static and dynamic performance of timber arch footbridges with different hanger configurations

    University essay from KTH/Bro- och stålbyggnad

    Author : ALEJANDRO GARCÍA GARCÍA; [2022]
    Keywords : Arch bridges; footbridge dynamics; critical load; bridge typology; parametric study;

    Abstract : The influence of the hanger configuration in the arch and deck bending moments under asymmetric loads is widely used nowadays for improved designs of arch bridges. In this work, by means of a parametric study, those hanger configurations that most efficiently increase both the natural frequencies and buckling factors are identified, simultaneously evaluating the dynamic and static performance of timber arch footbridges.

  4. 3. Investigation of methods to analyse global stability of a reinforced concrete stabilising core

    University essay from KTH/Bro- och stålbyggnad

    Author : Evelina Husak; Ellinor Persson; [2022]
    Keywords : ;

    Abstract : Ensuring the structural stability of a building is an evident requirement for the building to be safe to use. This becomes a qualified task for a structural engineer. Ensuring stability has become especially important nowadays while stabilising elements often are kept to a minimum and tall buildings are common. READ MORE

  5. 4. Buckling of End-Bearing Retaining Walls in Clay

    University essay from KTH/Jord- och bergmekanik

    Author : Fredrik Jansson; Nils Nilsson; [2018]
    Keywords : Berliner walls; Critical loads; buckling; finite element model; Eurocode 3; Berlinerspont; Rörspont; kritisk knäckningslast; knäckning; finit element modell; Eurocode 3;

    Abstract : The design of back-anchored retaining walls in Sweden has traditionally not included global elastic instability of the retaining wall as a possible failure mode. Eurocode 3 part 5 (SS-EN 1993-5) requires design of steel structural members for retaining walls to assess the risk of buckling if the normal force exceeds 4 % of the critical buckling load of the retaining wall.

  6. 5. Analytical calculation model used when dimensioning timber poles used as overhead power line supports

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Christopher Ekängen; [2018]
    Keywords : Calculation model; timber poles; overhead power line;

    Abstract : Overhead power lines are more reliable and cost effective than underground cables when it comes to power transmission. The overhead power lines are often suspended above ground using timber pole supports. READ MORE
