2. 1. Numerical simulation of weldment creep response

   Author : Peter Segle; KTH; []
   Keywords : ABAQUS; constraint effect; continuum damage mechanics; creep; creep crack growth; design; design code;

   Abstract : In-service inspections of high temperature pressureequipment show that weldments are prone to creep and fatiguedamage. It is not uncommon that severely damaged weldments arefound even before the design life of the component has beenreached. READ MORE

4. 2. Ice free roads using hydronic heating pavement with low temperature: Thermal properties of asphalt concretes and numerical simulations

   Author : Raheb Mirzanamadi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal properties; slippery condition; hydronic heating pavement; energy harvesting; asphalt concrete; road; anti-icing; finite element method;

   Abstract : A traditional method to mitigate the slippery conditions of a road is to spread out salt and sand on the road surface. However, salting causes corrosion on the road infrastructures, damage to surrounding vegetation and salification of fresh water. Hence, there is a need for alternative solutions to mitigate the slippery conditions. READ MORE

5. 3. Managing hydrogeological risks in underground construction

   Author : Johanna Merisalu; Chalmers tekniska högskola; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; risk management; groundwater drawdown-induced damages; cost–benefit analysis; uncertainties; decision support;

   Abstract : Groundwater leakage into underground constructions can cause groundwater drawdown and subsequently costly damages to objects impacted by changes in groundwater conditions. In order to reduce the damage risk, risk-reducing measures can be implemented. READ MORE

6. 4. Analytics-driven approaches supporting asset management of sanitary sewer networks

   Author : Emmanuel Okwori; Annelie Hedström; Maria Viklander; Marius Møller Rokstad; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data-driven; Decision Support; Network Robustness; VA-teknik; Urban Water Engineering;

   Abstract : Sewer blockages can cause overflows and flooding, with consequences such as damage to property and environmental pollution, risks to public health and economic loss. Despite the causes being understood, blockages in sewer networks may occur unpredictably. READ MORE

7. 5. System for Predictive Life cycle Management of Buildings and Infrastructures

   Author : Daniel Hallberg; Christer Sjöström; Michel Lacasse; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life Cycle Management System; service life; performance-over-time; maintenance management;

   Abstract : The Life Cycle Management System (LMS) aims at supporting decision-makers and engineers in their efforts to achieve a more optimised proactive life cycle design and maintenance management strategy. LMS is an open and integrative system, which has to be adapted and developed in order to meet the needs and requirements of users. READ MORE
