1. 1. Optimization of Material Cost and Carbon Footprint of Flat Reinforced Concrete Slabs with Simple Steel Piles : Designed according to Eurocode and Swedish appendix EKS

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Oskar Lönn; [2023]
   Keywords : Optimization; RC slab; Material cost; API;

   Abstract : When designing reinforced concrete (RC) slabs with steel piles various variables must be considered, from the internal force to the distance of piles. An endless number of designs are possible, leaving space for optimizing designs. READ MORE

3. 2. Semi-Automatic calculation of the stability of shear walls in multi-storey buildings

   University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

   Author : Erik Bolin; Emil Sjöstedt; [2022]
   Keywords : Horizontal stabilisation; Dynamo; Shear walls; Stability; Conceptual design phase; Visual programming; Openings in shear walls; Load distribution; Relative stiffness; Technology and Engineering;

   Abstract : Performing horizontal stability analysis in the conceptual design phase is time consuming and adjustments in the geometry of the building require new time consuming calculations. Often buildings are modelled in 3D modelling software such as Revit and Tekla but the calculations are often performed in a separate software. READ MORE

4. 3. Parametric Studies of Train-Track-Bridge Interaction : An evaluation of the dynamic amplification due to track irregularities for freight transport

   University essay from KTH/Bro- och stålbyggnad

   Author : Rasmus Elm Dahlman; Emil Lundberg; [2021]
   Keywords : Dynamics; dynamic amplification factor; railway bridge; train-track-bridge interaction; vehicle model; track irregularities; PSD; Dynamisk förstoringsfaktor; dynamik; järnvägsbroar; tåg-spår-bro interaktion; fordonsmodell; spårojämnheter; PSD;

   Abstract : In this thesis a train-track-bridge interaction (TTBI) model is developed in order to study the dynamic amplification from track irregularities on railway bridges traversed by freight trains. These simulations are of great importance since rail freight transport is expected to increase in order to meet the climate goals. READ MORE

5. 4. Long-term deformation of balanced cantilever bridges due to non-uniform creep and shrinkage

   University essay from KTH/Betongbyggnad

   Author : Sidra Akbar; Mathias Carlie; [2021]
   Keywords : Balanced cantilever bridges; box girder cross-section; concrete; non-uniform creep and shrinkage; Bažant’s B4 model; Eurocode 2; long-term deformations; finite element analysis; Freivorbau broar; lådtvärsnitt; betong; ojämnkrypningoch krympning; BažantsB4 modell; Eurokod 2; långtidsdeformationer; finita element analys;

   Abstract : Balanced cantilever bridges have historically experienced excessive deformations. Previous researchsuggeststhat the cause may be due to differential thickness in the box girder cross-section and underestimation of creep and shrinkage. READ MORE

6. 5. Shear strength of prestressed concrete beams without shear reinforcement : A comparison between equations

   University essay from KTH/Betongbyggnad

   Author : Bawan Azad; [2021]
   Keywords : Shear force; prestress concrete; design provisions; Eurocode; carrying capacity; parametric study; concrete beam; Tvärkraft; förspänd betong; dimensioneringsbestämmelser; Eurokod; bärförmåga; parameterstudie; betongbalk;

   Abstract : A new version of EN 1992-1-1, Eurocode 2 for Design of Concrete Structures, is under development and one of the most discussed topics is shear capacity for prestressed concrete beams without shear reinforcement, partly because shear failure occurs suddenly and can have catastrophic consequences. For the new version of Eurocode, there are a total of three proposed equations to replace the two equations that currently exist in EN 1992-1-1 for shear capacity of prestressed concrete beams without shear reinforcement.
