  1. 1. Plastic deformation of hot riveted joints acting in shear

    University essay from KTH/Bro- och stålbyggnad

    Author : Victor Gard; [2023]
    Keywords : ;

    Abstract : A popular way to maintain old rivet connections is to reuse the old connection and replace the old rivets with high grade steel bolts. In doing so the behavior of the joint can change due to the new geometry, where a gap between the new bolt and the rivet hole emerges. READ MORE

  3. 2. EVALUATION OF ENVIRONMENTAL AND TECHNICAL PERFORMANCE OF ALTERNATE FIBRES FOR SHOTCRETE IN TUNNELS

    University essay from KTH/Betongbyggnad

    Author : Shilpa Anand; [2022]
    Keywords : Shotcrete; Life cycle assessment; Environmental Product Declaration; Global warming potential; steel; basalt and synthetic fibres; flexural strength; energy absorption.;

    Abstract : Tunnels in hard and jointed rock are normally excavated in an arch shape to enable the rock mass to support its weight. Since the beginning of the 1980's, fibre reinforced shotcrete (FRS) in combination with rock bolts have been the dominating support method for hard rock tunnels. READ MORE

  4. 3. Steel-to-concrete connections in narrow concrete corners

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik

    Author : Daniel Carlson Bjernald; Emil Lönn; [2022]
    Keywords : Concrete; steel bolts; concrete failure modes; Abaqus; numerical calculations; concrete cone failure; concrete damaged plasticity; Technology and Engineering;

    Abstract : A commonly occurring problem when designing steel-to-concrete connections in corners with space deficits is the necessity for irregularly placed bolts with regards to design codes. The complexity of the calculations for the irregular placements of bolts generates the need to use simplified models during the design. READ MORE

  5. 4. Design and test of a robotic cell for stud bolt welding in heat exchangers for SWEP International AB

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Amparo Tarazona Ferrandis; [2021]
    Keywords : Technology and Engineering;

    Abstract : This project targeted automating production steps where stud bolts are welded on a heat exchanger within allowed perpendicularity and position requirements. Until now, this has been a manual process where an operator uses steel templates to position the bolts in the right place and manual welding guns to weld the bolts. READ MORE

  6. 5. Study of Production Drifts Stability and Assessment of Reinforcement Requirements at LKAB Konsuln Test-Mine Levels 436 and 486 Using Geologic Structures Data, and Modelling Software – Dips and Unwedge:  a Part of dp1 Project (Mine Layout and Technology) of the Sustainable Underground Mining (Sum) Project

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Oludare Joseph Olufe; [2021]
    Keywords : Drift stability analysis; underground excavation reinforcement; underground mining stability assessment; geologic structures; wedges modelling; rock mechanical analysis; Unwedge program; Dips program;

    Abstract : Study of Production Drifts Stability and Assessment of Reinforcement Requirements at LKAB Konsuln Test-Mine Levels 436 and 486 Using Geologic Structures Data, and Modelling Software - Dips and Unwedge:  a Part of dp1 Project (Mine Layout and Technology) of the Sustainable Underground Mining (Sum) Project Oludare Joseph Olufe Global population has been on exponential increase over the past half century. The population explosion is driving massive urbanization and infrastructure developments across the globe, which result in huge demand for metals, especially steel. READ MORE
