Multiscale studies on corrosion-induced bond deterioration of reinforced concrete
Background The development of technology enables the study of the corrosion of steel bars in concrete at various scales (such as micro and macro), facilitating a comprehensive exploration of the effects of corrosion phenomena on reinforced concrete structures. There is still a lack of research on...

Kiruna Hospital Building
Background Kiruna city has experienced ground subsidence and vibrations due to mining activities within the last years. This has caused cracks and inconveniences for the occupants in some buildings in the city. The hospital building has also been affected and cracks have developed in different part...
-
H2SIPP
Background Despite several decades of research on hydrogen releases, there are still important gaps to be filled. The main knowledge gaps relate to jet releases above ground. Those are mostly related to radiation, where the treatment thus far has been oversimplified, where the difference between ...

Improving Sustainability in Concrete Structures using Corrosion-Resistant FRP Reinforcements: A Shear Behavior Study
Background Sweden's extensive coastline necessitates robust coastal infrastructure, crucial for its economy but challenged by corrosion from deicing salts and marine environments, affecting over 10,000 bridges. This corrosion, contributing to annual losses of 4% of Sweden's GNP, undermines infrastr...

Snow galleries on Malmbanan - Monitor snow build-up and alert when it is time to clean it
Background The snow galleries along the Iron Ore railway line in northern Sweden have faced problems in recent years due to increasingly large snow loads with several galleries been damaged. These incidents motivated an evaluation of the maximum load supported by the galleries before collapse. In 2...

Sustainable Construction in Artic Climate – Residual prestressing in prestressed concrete structures
Background The construction industry and built environment in Europe allocate half of their expenditure to repairs, maintenance, and remediation, indicating a significant economic impact due to aging infrastructure. With post-war infrastructure nearing its design life, there's an urgent need for th...

Robust property protection in fire
Background As a consequence of several serious fires in modularized wooden buildings, a number of entrepreneurs have joined forces to address the challenges specific to their structural methods.
-
FINAST
Background The project contributes to the green transition and a carbon dioxide-neutral steel industry through research efforts in collaboration between Luleå University of Technology, Swerim, and SSAB. The overall goal of the FINAST project is to, through industry-related research and collaboratio...

Kalix bridge project - Condition assessment of existing bridges
Replacing an existing bridge often costs two to three times its present value and it is associated with substantial carbon emissions, so it is environmentally important to extend bridges’ lifetimes in a bid to make the built environment more sustainable.
-
Sparks from forestry machinery: A possible or impossible source of forest fires?
Sparks from the contact between metal and stone have been widely debated in recent years, both inside and outside the scientific sphere, especially in forestry, because many of the major forest fires in Sweden are considered to have started from forest machines in work. Exactly how this went, howeve...

TruBridges
Multi and interdisciplinary method to identify the true capacity of concrete bridges.
-
Safe dams
Dams are large structures and are often made out of concrete, a heterogenous engineered material, and built on natural foundations with notorious variations.
-
Characterization of train-induced aerodynamic loads on railway noise barriers
Noise barriers need to be installed along high-speed railway lines to protect nearby inhabitants from the noise pollution caused by the running of high-speed trains.
-
Development of a proof loading method for railway bridges
Special transports that exceed the line capacity are planned in 2024 along the Haparanda line in Northern Sweden.

Partial composite action
Creating design guidance for strengthening of steel girder bridges by introducing partial composite action.
-
Demolition of prestressed concrete bridge - Experience feedback for maintenance - New construction
European infrastructure built after the end of the second World War has reached, or is near to, the end of its nominal design life. With an older generation of bridges, finding the most suitable demolition process for a specific bridge becomes a priority task where knowledge about the area and possi...

Digital Twins for asset management of structures
Current inspection and management processes for civil structures are time-consuming and can even be inaccurate.
-
Using Sustainable Biochar to Lower the Detrimental Effects of Fire in Concrete
At present, concrete has two major issues. On one hand, although concrete is not flammable, it suffers significantly from fire damage.
-
Sustainable technologies for the direct and bulk conversion of waste biomass into graphene
Despite being considered as the ‘wonder material’, graphene’s use is limited by the quantity during its production.
