1. Corrosion of steel bars in fibre reinforced concrete: corrosion mechanisms and structural performance
Sammanfattning : The viability of employing fibre reinforcement to improve the durability performance of RC structures by delaying and/or reducing rebar corrosion and by mitigating the structural impact of corrosion-induced damage have been investigated. Given the enhanced crack control of FRC, it could be advantageous to use fibres in civil engineering structures to decrease the ingress of corrosion-initiation substances. LÄS MER
2. Flexural Buckling of High-Strength Steel Columns
Sammanfattning : The European standards dealing with design rules and recommendations for steel structures have been under revision in the past years due to the increased use of high-strength steels. High-strength steels popularity increased at a steady pace in the last decades since they allow for more light-weighted solutions than conventional steels. LÄS MER
3. Structural assessment procedures for existing concrete bridges : Experiences from failure tests of the Kiruna Bridge
Sammanfattning : Assessing existing bridges is an important task in the sustainable management ofinfrastructure. In practice, structural bridge assessments are usually conducted usingtraditional and standardised methods, despite knowledge that these methods oftenprovide conservative estimates. LÄS MER
4. Assessment of shear and energy‐absorption capacity of reinforced concrete elements under impulsive loads
Sammanfattning : Impulsive loads have been observed to cause brittle shear failure in reinforced concrete elements designed for ductile failure modes under static loads. Brittle failure modes exhibit poorer energy absorption capabilities compared to ductile flexural failure modes due to their limited deformation capacity, leading to premature failure. LÄS MER
5. Strengthening reinforced concrete structures with FRP composites
Sammanfattning : Civil infrastructures made of reinforced concrete (RC) play an important role in the economic activities and services of society. However, signs of deterioration and functional deficiency are commonly found in existing RC structures. Thus, there is a great demand for upgrading the capacity and performance of existing concrete structures. LÄS MER
