6. Development of connections for fibre reinforced bridge elements and an analysis of sustainability
Sammanfattning : The deterioration of existing bridge structures due to a number of causes has led researchersto pursue new construction materials with high performance, such as fibre reinforced polymer(FRP) composite materials. The inherent properties of FRP materials are their light weight,high strength and high resistance to aggressive environments. LÄS MER
7. Stress-laminated-timber bridge decks subjected to ultimate loads
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
8. Bracing of steel bridges during construction; theory, full-scale tests and simulations
Sammanfattning : A number of steel bridges have suffered lateral-torsional failure during their construction due to their lacking adequate lateral and/or rotational stiffness. In most cases, slight bracing can be of great benefit to the main girders involved through their controlling out-of-plane deformations and enabling the resistance that is needed to be achieved.

9. Testing and finite element modeling of wooden stairs and bridge decks
Sammanfattning : Development of new products in the joinery industry has traditionally been based on testing of prototypes. Computer-aided design tools and finite element analysis can supplement traditional prototype testing and improve the product development process. LÄS MER
10. Mechanisms of Blister Formation on Concrete Bridge Decks with Waterprooving Asphalt Pavement Systems
Sammanfattning : Bridge decks are commonly subjected to harsh environmental conditions that often lead to serious corrosion problems triggered by blisters under the hot mix asphalt bridge deck surfacing and secretly evolving during weather exposure until damage is often detected too late. Blisters may form under both the waterproofing dense mastic asphalt layer or under the waterproofing membrane which is often applied as additional water protection under the mastic asphalt (MA).
