  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. Linear and non-linear FE-analysis of cracking behavior of wing walls in integral bridges

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

    Author : Andreas Ekman; Christoffer Sandin; [2018]
    Keywords : Non linear FE-modelling; Concrete Damage Plasticity; Wing wall; Crack propagation; Serviceability Limit State; Slab Frame Bridge; Technology and Engineering;

    Abstract : Wing walls on slab frame integral bridges has traditionally been designed for mainly earth pressure and its self-weight. It has also been designed separately from the rest of the bridge. Traditionally no 3D effects have been considered in the design of the wing walls. READ MORE

  4. 3. Analyses of Two Ice Class Rules : for The Design Process of a Container Ship

    University essay from KTH/Marina system

    Author : Yixiang Su; [2017]
    Keywords : IACS polar class; FSICR; Ice -ship collision; non-linear FE modelling; ANSYS;

    Abstract : During ice voyages, level ice and iceberg with huge inertia force can cause large deformation and even damage on the ship hull structure. Hence the hull structure for ice voyage requires higher strength than it for open water voyages. A container ship will be re-designed for ice voyages in the thesis. READ MORE

  5. 4. Pilot Testing of a Hydraulic Bridge Exciter

    University essay from KTH/Bro- och stålbyggnad

    Author : Richard Borg; Olivier Dymén; [2015]
    Keywords : Hydraulic bridge exciter; controlled excitation; modal testing; experimental modal analysis; railway bridges; measurements; load shaker; FEM; FE-modelling; script; Hydraulisk broexciterare; kontrollerad excitering; modala tester; experimentell modal analys; järnvägsbroar; mätningar; lastexciterare; FEM; FE-modellering; script;

    Abstract : In the design of a railway bridge that is meant for train speeds larger than 200 km/h, the Swedish Traffic Administration requires a dynamic analysis in addition to the conventional static design. The models used for static design may not always be suitable for dynamic analysis, which could lead to inaccurate estimations of the dynamic response. READ MORE
