21. Environmental Actions and Response - Reinforced Concrete Structures exposed in Road and Marine Environments
Sammanfattning : The expenses for repair, maintenance and remediation of existing concrete structures have significantly increased. A large proportion of these expenses are due to problems related to a lacking durability of the structure. LÄS MER
22. Assessment of Concrete Structures Including Corrosion and Cracks
Sammanfattning : Reinforced concrete (RC) structures constitute a major proportion of the built environment and society relies continuously on their service. Many of these structures were built in the era following the Second World War and are thus approaching the end of their intended service life. LÄS MER
23. Warhead penetration in concrete protective structures
Sammanfattning : The analysis of penetration of warheads in concrete protective structures is an important part of the study of weapon effects on protective structures. This type of analysis requires that the design load in the form of a warhead is determined, and its characteristic and performance within a protective structure is known. LÄS MER
24. Strengthening of concrete structures with CFRP : shear strengthening and full scale applications
Sammanfattning : Structures can be in need of strengtheing due to many reasons, which are presented in this thesis. A literature review gives the existing methods for enhancing a structures load bearing capacity. In this thesis focus will be set at external bonding with carbon fibre reinforced polymers. LÄS MER
25. Cracking in concrete : crack prevention with air-cooling and crack distribution with steel fibre reinforcement
Sammanfattning : This Licentiate Thesis consists of four parts. The first two parts, paper A and B, deal with air-cooling by means of embedded pipes in order to reduce thermal cracking in concrete structures. These two papers are submitted for publication to RILEM Journal; ‘Materials and Structures'. LÄS MER
