1. 1. Structural assessment procedures for existing concrete bridges : Experiences from failure tests of the Kiruna Bridge

   Författare :Niklas Bagge; Björn Täljsten; Paulo Cruz; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anchorage; carbon fibre reinforced polymers; concrete; existing bridges; finite element analysis; flexure; full-scale test; load-carrying capacity; residual prestress force; punching; safety verification; shear; structural assessment; structural behaviour; Structural Engineering; Konstruktionsteknik;

   Sammanfattning : Assessing existing bridges is an important task in the sustainable management ofinfrastructure. In practice, structural bridge assessments are usually conducted usingtraditional and standardised methods, despite knowledge that these methods oftenprovide conservative estimates. LÄS MER

3. 2. Structural Analysis of Existing RC Bridge Deck Slabs Structural Analysis of Existing RC Bridge Deck Slabs

   Författare :Jiangpeng Shu; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; load-carrying capacity; assessment; Reinforced concrete RC bridge deck slabs; structural behaviour; Finite element FE analyses;

   Sammanfattning : Due to ageing of the bridge stock, continuously increasing load requirements, the need for assessing existing bridges is becoming increasingly important. Reinforced concrete (RC) bridge deck slabs are among the most critical parts to the load carrying capacity of bridges. LÄS MER

4. 3. An Algorithmic Framework for Intelligent Concrete Structural Defects Detection and Classification

   Författare :Ali Mirzazade; Björn Täljsten; Cosmin Popescu; Thomas Blanksvärd; Diogo Rodrigo Ferreira Ribeiro; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil Engineering Structures; defect detection; Structural Health Assessment; Bridge Inspection; Computer Vision; Point-Cloud Generation; Severity Assessment; Machine Learning Regression; Bridge 3D Modeling; Unmanned Inspections; Byggkonstruktion; Structural Engineering;

   Sammanfattning : The primary objective of inspecting concrete civil structures is to gather information concerning the deterioration of concrete elements, including issues like concrete cover cracking, delamination, or corrosion. Typically, this data is documented through field inspection notes, hand-drawn sketches, and photographs. LÄS MER

5. 4. Reliability-based Assessment of Concrete Dam Stability

   Författare :Marie Westberg; Avdelningen för Konstruktionsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; assessment; stability; concrete dam; structural reliability analysis; probability; uplift; system reliability;

   Sammanfattning : Risk management is increasingly used in dam safety and includes risk analysis, risk evaluation and risk reduction. Structural Reliability Analysis (SRA) is a probabilistic methodology that may be used in the risk assessment process. LÄS MER

7. 5. Protein Model Quality Assessment : A Machine Learning Approach

   Författare :Karolis Uziela; Arne Elofsson; Liam McGuffin; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein Model Quality Assessment; structural bioinformatics; machine learning; deep learning; support vector machine; proq; Artificial Neural Network; protein structure prediction; Biochemistry towards Bioinformatics; biokemi med inriktning mot bioinformatik;

   Sammanfattning : Many protein structure prediction programs exist and they can efficiently generate a number of protein models of a varying quality. One of the problems is that it is difficult to know which model is the best one for a given target sequence. Selecting the best model is one of the major tasks of Model Quality Assessment Programs (MQAPs). LÄS MER
