1. Shear in Concrete Structural Elements Subjected to Dynamic Loads
Sammanfattning : Concrete structural elements subjected to severe dynamic loads such as explosions at close range may cause shear failures. In the Oklahoma City bombing in 1995 two concrete columns on the ground level were reported to have failed in shear. LÄS MER
2. Strengthening of concrete structures by the use of mineral based composites : system and design models for flexure and shear
Sammanfattning : A great number of society's resources are invested in existing concrete structures, such as bridges, tunnels, different kind of buildings etc. All of these structures have both an expected function and an expected life span. However, both the function and the life span can be influenced by external factors, e.g. LÄS MER
3. Externally unbonded post-tensioned CFRP tendons : a system solution
Sammanfattning : The introduction of Fibre Reinforced Polymers (FRP) to the civil engineering market in the late 1980s resulted in the emergence of a range of new tools for rehabilitating and strengthening concrete structures. Strengthening using FRPs is typically accomplished using non-prestressed externally bonded FRPs. LÄS MER
