1. 6. Recovery from Acidification - Policy Oriented Dynamic Modeling

   Författare :Liisa Fransson; Institutioner vid LTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Petrology; mineralogy; geochemistry; Petrologi; mineralogi; geokemi; Chemical technology and engineering; target loads; sea-salt episode; sulfate adsorption; SAFE; LRTAP; critical loads; integrated assessment;

   Sammanfattning : Dynamic biogeochemistry models are important tools for determining the time-scales of recovery from acidification. In the review process of the 1999 UNECE LRTAP Gothenburg protocol, results from dynamic models will probably be included when determining further reductions of acidifying emissions. LÄS MER

3. 7. Pavement Response to Moving Loads

   Författare :Parisa Khavassefat; Björn Birgisson; Denis Jelagin; Andrew Collop; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The response of flexible pavements at vehicle-road interaction has been studied in this thesis. A quasi-static and a dynamic framework for analysing the pavement structure under moving load has been developed. Both frameworks are general, robust and computationally efficient. LÄS MER

7. 10. Assessment of shear and energy‐absorption capacity of reinforced concrete elements under impulsive loads

   Författare :Viktor Peterson; Anders Ansell; Mikael Hallgren; Yanyan Sha; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Impulsive loads; impact; blast; shear reinforcement; shear failure; Betongbyggnad; Concrete Structures;

   Sammanfattning : Impulsive loads have been observed to cause brittle shear failure in reinforced concrete elements designed for ductile failure modes under static loads. Brittle failure modes exhibit poorer energy absorption capabilities compared to ductile flexural failure modes due to their limited deformation capacity, leading to premature failure. LÄS MER
