  1. 1. Making the connection : Are post-tensioned CLT walls an economically sound option?

    University essay from Uppsala universitet/Byggteknik och byggd miljö

    Author : Jakob Mehlig; Elisabeth Wade; [2021]
    Keywords : CLT; post-tensioned; shear wall; pre-stressed; cost; connections; stability;

    Abstract : This thesis aims to compare the cost of post-tensioned connection systems with conventional connections for the transferal of uplift forces in CLT stabilising walls. The desire for taller timber buildings has increased over time, in part due to environmental aspects but also to meet demands from an urbanizing population. READ MORE

  3. 2. 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

  4. 3. Analysis of post-tensioned concrete box-girder bridges : A comparison of Incremental launching and Movable scaffolding system

    University essay from KTH/Bro- och stålbyggnad

    Author : Hamad El Hamad; Furkan Tanhan; [2018]
    Keywords : Movable scaffolding system; MSS; Incremental launching; post-tension; prestress; slen- derness; box-girder; Stockholm Bypass; Movable scaffolding system; MSS; Etappvis lansering; efterspänning; förspänning; slankhet; box-girder; Förbifart Stockholm;

    Abstract : When designing a bridge it is of high importance that the geometry for the cross section is optimized for the structure. This is partly due to the influence of the amount of material needed and its impact on the budget and environment. READ MORE
