11. Composite Columns of Hollow Steel Sections Filled with High Strength Concrete
Sammanfattning : In the design of buildings today, great effort is made to increase the structural flexibility. This has resulted in a demand for columns with reduced cross sections. To achieve a high load bearing capacity with a small cross sectional area, it is worthwhile to study the possibility of utilizing high strength concrete and composite effects. LÄS MER
12. Mechanical Characterization of Engineering Materials by Modal Testing
Sammanfattning : This thesis deals with the use of modal testing for establishing elastic constants of engineering materials and for indicating material variability in terms of stiffness and damping properties. The methodology using modal testing techniques, is applied to timber beams, high strength concrete prisms, wood-based panels (oriented strand board and chipboard), an aluminium alloy panel and plastic laminate panels (high-pressure laminate).

14. Durability of fire exposed concrete : Experimental Studies Focusing on Stiffness & Transport Properties
Sammanfattning : Road and rail tunnels are important parts of the modern infrastructure. High strength concrete (HSC) is commonly used for tunnels and other civil engineering structures, since it allows high load carrying capacity and long service life. In general, Swedish road and rail tunnels should be designed for a service life of 120 years. LÄS MER
15. 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
