1. 1. Externally unbonded post-tensioned CFRP tendons : a system solution

   Författare :Anders Bennitz; Chris Burgoyne; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFRP; prestress; tendon; external; unbonded; anchorage; beams; CFRP; förspänning; vajer; utanpåliggande; icke vidhäftande; förankring; Structural Engineering; Konstruktionsteknik;

   Sammanfattning : The introduction of Fibre Reinforced Polymers (FRP) to the civil engineering market in the late 1980s resulted in the emergence of a range of new tools for rehabilitating and strengthening concrete structures. Strengthening using FRPs is typically accomplished using non-prestressed externally bonded FRPs. LÄS MER

4. 3. A Microdata Analysis Approach to Transport Infrastructure Maintenance

   Författare :Kristin Svenson; Lars Rönnegård; Karin Edvardsson; Nasir Gharaibeh; Högskolan Dalarna; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transport Infrastructure Asset Management; Transport Infrastructure Maintenance; Statistical Modeling; Microdata Analysis; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

   Sammanfattning : Maintenance of transport infrastructure assets is widely advocated as the key in minimizing current and future costs of the transportation network. While effective maintenance decisions are often a result of engineering skills and practical knowledge, efficient decisions must also account for the net result over an asset's life-cycle. LÄS MER

5. 4. Performance Measures of Road Infrastructure - A Life Cycle Thinking Approach

   Författare :Babak Ebrahimi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road infrastructure; Life Cycle Assessment LCA ; Lifetime Estimation; Geographic Information System GIS ; Life Cycle Thinking LCT ; Material Flow Analysis MFA ;

   Sammanfattning : Roads have been an important asset of human society and the approach we adopt towards planning, designing, constructing, operating, and maintaining of the road infrastructure has significant consequences in the long-term for not only the humans, but all species on planet Earth. Hence, the lifecycle performance of the road infrastructure that sustain our socioeconomic development with a low environmental impact, while fulfilling their technical and functional requirements is of critical importance and needs to be improved.

7. 5. Towards Systemic Governance of Critical Infrastructure Protection : State and Relevance of a Swedish Case

   Författare :Christine Große; Aron Larsson; Olof Björkqvist; Pär M. Olausson; Alexander Fekete; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systemic Thinking; Infrastructure; Governance; Critical Infrastructure Protection; Complex Systems; Soft Operations Research; design-oriented Information Systems Research; Integrative System Analysis; KISA; STYREL; Multi-level Planning; Adaption; Emergence; Entropy; Systemic Governance;

   Sammanfattning : The protection of infrastructure that is critical to society’s functionality, survival and progression has gained significance for both national security and research because of its large-scale and interdependent nature. Critical infrastructure can be viewed as a complex, socio-technical system-of-systems that imposes extensive requirements on governance efforts to foster critical infrastructure protection (CIP), regardless of whether it involves public organisations, private organisations or both.
