1. 21. Performance of Stress-Laminated-Timber Bridge Decks

   Författare :Kristoffer K J Ekholm; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; butt joints; non-linear modelling; stress-laminated timber; linear modelling; prestressing; timber bridges; interlaminar slip; FE modelling; laboratory tests; durability;

   Sammanfattning : Stress-laminated-timber (SLT) bridge decks are a satisfactory alternative to conventional short-span bridges in terms of cost and performance. SLT decks are made from a number of timber or glulam beams positioned side by side and stressed together using high-strength steel bars. LÄS MER

3. 22. Stress-laminated-timber bridge decks subjected to ultimate loads

   Författare :Kristoffer K J Ekholm; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultimate-load tests; Stress-laminated timber; Timber bridges;

   Sammanfattning : Stress-laminated-timber (SLT) bridge decks are a satisfactory alternative to conventional short-span bridges in terms of cost and performance. SLT decks are made from several deck laminations positioned side by side. LÄS MER

4. 23. Application of monitoring to dynamic characterization and damage detection in bridges

   Författare :Ignacio Gonzalez; Raid Karoumi; Eugene O'Brien; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural health monitoring; Traffic monitoring; Bridge monitoring; Bridge Weigh-In-Motion; BWIM; Damage detection; Suspension bridge bearings; Axle loads; Dynamics; Temperature effect;

   Sammanfattning : The field of bridge monitoring is one of rapid development. Advances in sensor technologies, in data communication and processing algorithms all affect the possibilities of Structural Monitoring in Bridges. LÄS MER

5. 24. Plastic Shrinkage Cracking in Concrete

   Författare :Faez Sayahi; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

   Sammanfattning : Early-age (up to 24 hours after casting) cracking may become problematic in any concrete structure. It can damage the aesthetics of the concrete member and decrease the durability and serviceability by facilitating the ingress of harmful material. LÄS MER

7. 25. On modelling of slope stability in sensitive clay

   Författare :Carolina Sellin; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; constitutive modelling; mobilisation of shear strength; destructuration; slope stability; anisotropy; sensitive clay; rate dependence;

   Sammanfattning : The stability of natural slopes is a global problem, with the number of landslides and the associated socioeconomic losses increasing, as a result of the global trend of urbanisation, deforestation and changed weather patterns. The available methods for identifying potential failure modes and assessing the stability, however, overly simplify the modelled soil behaviour within a slope, which might lead to unnecessary mitigation measures or non-conservative results.
