2. 1. Risk Assessment of Groundwater Drawdown in Subsidence Sensitive Areas

   Author : Jonas Sundell; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inverse modelling; cost-benefit analysis; probabilistic; groundwater drawdown; urban hydrogeology; economic valuation; groundwater leakage; subsidence; value of information analysis.; spatial variability; uncertainty quantification; risk assessment;

   Abstract : Groundwater leakage into sub-surface constructions can result in drawdown, subsidence in compressible materials, and costly damage to buildings and installations. When planning for sub-surface constructions where there is a risk for land subsidence due to groundwater drawdown, the need for safety measures must be carefully evaluated and managed. READ MORE

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

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

   Abstract : 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. READ MORE

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

   Author : Niklas Bagge; Björn Täljsten; Paulo Cruz; Luleå tekniska universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

6. 4. Reliability-based assessment procedures for existing concrete structures

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

   Abstract : 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. READ MORE

7. 5. Refining the fatigue assessment procedure of existing steel bridges

   Author : John Leander; Raid Karoumi; Bert Norlin; John D. Sørensen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fatigue; Steel bridges; Assessment; Reliability; Monitoring; Utmattning; stålbroar; bärighetsberäkning; tillförlitlighet; mätningar; Söderström; getingmidjan;

   Abstract : This thesis treats the fatigue assessment process of steel bridges. The purpose is to identify areas with potential of enhancement with an overall aim of attaining a longer service life. The aging bridge stock in Sweden and in many other developed countries is an impending economical burden. READ MORE
