1. 21. Serviceability Limit State for Steel Girders during Bridge Launching - A Patch Loading Problem

   Författare :Per Granath; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel; patch loading; plate girders; bridge launching; post-buckling; behaviour; finite element analysis; serviceability limit state;

   Sammanfattning : Incremental launching is a construction method in which bridge girders are first assembled in the vicinity of the future permanent position of the bridge. When the elements have been welded together the girders are launched to their permanent position. LÄS MER

3. 22. Tendon Healing : Mechanical Loading, Microdamage and Gene Expression

   Författare :Malin Hammerman; Per Aspenberg; Pernilla Eliasson; Ludvig Backman; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Mechanical loading and the inflammatory response during tendon healing might be important for the healing process. Mechanical loading can improve the healing tendon but the mechanism is not fully understood. LÄS MER

4. 23. Influence of neuromodulators and mechanical loading on pathological cell and tissue characteristics in tendinosis

   Författare :Gloria Fong; Patrik Danielson; Alex Scott; Ludvig Backman; Paul Ackermann; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; substance P; acetylcholine; transforming growth factor; neuromodulators; mechanical loading; tendinosis; anatomi; Human Anatomy;

   Sammanfattning : Background: Tendinosis is a painful chronic, degenerative condition characterized by objective changes in the tissue structure of a tendon. Hallmark features in tendinosis tendons include increased number of cells (hypercellularity), extracellular matrix (ECM) degradation and disorganized collagen. LÄS MER

5. 24. Excess pore water pressure generation in fine granular materials under cyclic loading -A laboratory study

   Författare :Tan Manh Do; Jan Laue; M. Kubilay Kelesoglu; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Excess pore water pressure; migration of particles; fine granular materials; cyclic loading; Soil Mechanics; Geoteknik;

   Sammanfattning : Abstract Excess pore water pressure can be generated in subgrades of both railway and pavement sub-structures under cyclic loading caused by heavy traffic. When saturated subgrades are subjected to cyclic loading, excess pore water pressures accumulate over time which then could lead to migration of particles into overlying layers. LÄS MER

7. 25. Patch loading of stainless steel girders : experiments and finite element analyses

   Författare :Emma Unosson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

   Sammanfattning : This thesis deals with the behaviour of stainless steel girders subjected to patch loading. The current loading situation arises for example at beam- column connections or at crane girders where the load is travelling along a girder. At bridge launching it is also important to consider patch loading. LÄS MER
