  1. 1. Modelling Time-Dependent Effects for Segmentally Constructed Prestressed Concrete Bridges

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för bygg- och miljöteknologi

    Author : Niclas Elfving; Joel Sunesson; [2021]
    Keywords : Concrete; Creep; Segmentally constructed; Prestressing; Post-tensioning; Viscoelastic; Eurocode; Finite Element; Shell elements; Beam elements; Time-dependant; Steel relaxation.; Technology and Engineering;

    Abstract : Tidsberoende effekter, såsom krypning, krympning och stålrelaxation, är ofta svåra att prediktera när det kommer till förspända betongkonstruktioner. Krypning som ett fenomen är komplicerat och förenklas därför i gällande byggnormer (Eurocode), för att underlätta konstruktörens arbete. READ MORE

  2. 2. Form Finding of Grid Shells - a Parametric Approach using Dynamic Relaxation

    University essay from KTH/Mekanik

    Author : Henrik Green; Daniel Lauri; [2017]
    Keywords : ;

    Abstract : The rapid development of computational capacity in recent years has expanded the possibilities of digital modelling in architectural design. Parametric design has emerged from these possibilities with a capacity to generate complex geometries which call for advanced structural systems. READ MORE

  3. 3. Characterization of viscoelastic properties of an epoxy composite and simulation of time dependent deformation of an annulus seal under load.

    University essay from KTH/Hållfasthetslära (Inst.)

    Author : Christopher Muturi; [2014]
    Keywords : ;

    Abstract : A new sealing stand-alone tool, i.e. CannSeal to produce a barrier packer or zonal isolation in oil/gas wells has been developed by a Norwegian company (AGR CannSeal AS). The tool allows injection of a fluid into the annulus between the production casing and the surroundings in an oil/gas well. READ MORE

  4. 4. Design of a CFRP-to-steel joint for a bus engine mount and experimental testing of joint relaxation

    University essay from KTH/Lättkonstruktioner

    Author : Mikael Ljunkrantz; [2012]
    Keywords : ;

    Abstract : The objective of this study is to investigate aspects of hybrid joint design for a shear connection. Part 1 is design considerations and a case study based on a engine mount. In Part 2, an experimental study is conducted regarding how relaxation and creep affects properties of a hybrid joint between carbon fiber vinylester and steel. READ MORE

  5. 5. A feasibility study of a network arch bridge with glulam arches

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Erik Nylander; [2012]
    Keywords : Technology and Engineering;

    Abstract : The drive of using more renewable material has increased the interest in timber bridges. This makes it more interesting in looking in to new ways of constructing timber bridges. Most timber bridges for road traffic are using an arch with a hanging deck suspended from the arch using vertical hangers. READ MORE
