1. Supply Chain Resilience: Industrial Manufactures’ Use of Disruptive Technologies
Master-uppsats, Jönköping UniversitySammanfattning : With a purpose to provide insights on how to reduce the impact of future disruptive events on the supply chain and to raise awareness of the potential applications of disruptive technologies (DTs), this thesis will analyze the use of 3-Dimensional Printing (3DP), Big Data (BD), and Internet of Things (IoT) in Supply Chain Management (SCM). The devastating impact of the COVID-19 pandemic has highlighted the need for greater Supply Chain Resilience (SCR), as disruptions can have a domino effect and damage co-dependent supply chain actors.

2. Strengthening of non-composite bridges by Partial Composite Action
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : A common bridge type is the steel-concrete bridge where the concrete deck is built over steel girders. In many earlier designs the bridge type was often built as non-composite, which means that the concrete deck and the steel girder has no shear connection at the steel-concrete interface and therefore bend as individual components.

3. Performance of reinforced concrete bridges strengthened with Carbon Fiber Reinforced Polymers : Case study: Essinge Bridge over Pampaslänken
Master-uppsats, KTH/Bro- och stålbyggnad; KTH/Jord- och bergmekanikSammanfattning : This master thesis deals with the performance of existing reinforced concrete bridges strengthened with externally bonded carbon fibre reinforced polymers (CFRP). One of the main aims of this work is to understand the functionality of such an external strengthening method applied to a concave surface in a heavy concrete structure such as a bridge. LÄS MER
4. Non-Linear FE-Analysis of a Composite Action Girder with Coiled Spring Pins as Shear Connectors
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : For bridges to cope with increased requirements such as increased loads, strengthening work can be carried out. In cases where older steel-concrete bridges do not have a composite action, an alternative is to create composite-action to achieve a higher flexural strength. It is introduced by post-installing shear connectors. LÄS MER
5. Achieving Composite Action in Existing Bridges : With post-installed shear connectors
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : The increased amount of traffic combined with higher traffic loads leads to many existing bridges needing strengthening in the future to ensure their expected lifespan. This means the bridge owners will be focusing more on strengthening projects and smart solutions will be crucial for preserving a healthy bridge stock. LÄS MER
