4. 3. Bridge Monitoring to Allow for Reliable Dynamic FE Modelling : A Case Study of the New Årsta Railway Bridge

   Författare :Johan Wiberg; Håkan Sundquist; Raid Karoumi; Björn Paulsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bridge monitoring; FE modelling; signal analysis; torsion; warping; modulus of elasticity; natural frequency; damping; finite differences; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

   Sammanfattning : Today’s bridge design work in many cases demands a trustworthy dynamic analysis instead of using the traditional dynamic amplification factors. In this thesis a reliable 3D Bernoulli-Euler beam finite element model of the New Årsta Railway Bridge was prepared for thorough dynamic analysis using in situ bridge monitoring for correlation.

5. 4. Structural health monitoring using modern sensor technology : long-term monitoring of the New Årsta Railway Bridge

   Författare :Merit Enckell; Håkan Sundqvist; Daniele Inaudi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Health Monitoring; bridges; sensory technology; fibre optics; concrete.; Building engineering; Byggnadsteknik;

   Sammanfattning : Structural Health Monitoring (SHM) is a helpful tool for engineers in order to control and verify the structural behaviour. SHM also guides the engineers and owners of structures in decision making concerning the maintenance, economy and safety of structures. LÄS MER

7. 5. Prefabricated composite bridges : a study of dry deck joints

   Författare :Robert Hällmark; Ian May; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bridge construction; prefabrication; monitoring; Steel Structures; Stålbyggnad;

   Sammanfattning : This thesis deals with prefabricated composite bridges in general, and prefabricated concrete deck elements with dry joints in particular.As outlined in Paper I and Chapter 2 prefabrication has several advantages over in situ construction, and has hence been discussed for decades in the construction business.
