1. 1. Service Life Assessment of Harbor Structures - Case studies of chloride ingress into concrete and sheet piling corrosion rates

   Författare :Henrik Wall; Avdelningen för Byggnadsmaterial; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chloride ingress; sampling methods; corrosion rates; sheet piling; ultra-sonic measurements; service life; durability; quay structures; harbor structures;

   Sammanfattning : The two most used building materials in harbor structures are undoubtedly steel and concrete. These two materials are often combined in the structures of wharfs and quays where the steel sheet pile walls often have cap beams of reinforced concrete. LÄS MER

3. 2. Service life of repaired concrete bridge decks

   Författare :Johatan Paulsson-Tralla; KTH; []
   Nyckelord :;

   Sammanfattning : Pre-mature deterioration of reinforced concrete causesproblems world-wide and the search for reliable cost effectiveand environmental friendly repairs is intense. The service lifeof the repaired structure is important in order to establishthe annual cost and environmental impact for differentalternatives. LÄS MER

4. 3. Scalable Analysis of Large Datasets in Life Sciences

   Författare :Laeeq Ahmed; Erwin Laure; Ola Spjuth; Ake Edlund; Vincent Breton; KTH; []

   Sammanfattning : We are experiencing a deluge of data in all fields of scientific and business research, particularly in the life sciences, due to the development of better instrumentation and the rapid advancements that have occurred in information technology in recent times. There are major challenges when it comes to handling such large amounts of data. LÄS MER

5. 4. Environmental actions on concrete exposed in marine and road environments and its response - Consequences for the initiation of chloride induced reinforcement corrosion

   Författare :Anders Lindvall; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; corrosion; de-icing salt; road conditions; marine conditions; service life predictions; reinforcement; chloride; concrete; moisture conditions; environmental actions;

   Sammanfattning : The object of the study presented here has been to describe, further explain and model the influence of the exposure conditions on reinforced concrete structures and the consequences on their expected service life. The focus has been on investigating and quantifying the exposure conditions for structures in marine and road conditions exposed to chloride ions. LÄS MER

7. 5. Reliability-based assessment procedures for existing concrete structures

   Författare :Joakim Jeppsson; Avdelningen för Konstruktionsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete; reliability theory; service life; assessment; monitoring; hydraulic engineering; Civil engineering; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

   Sammanfattning : A feasibility study of reliability theory as a tool for the assessment of present safety and residual service life of damaged concrete structures has been performed in order to find a transparent methodology for the assessment procedure. It is concluded that the current guidelines are open to interpretation and that the variation in the results obtained regarding the structural safety is too great to be acceptable. LÄS MER
