26. Probabilistic System Effects in Timber Structures
Sammanfattning : The main purpose of the performed research presented in this thesis is to increase the understanding of the effect of variability of strength properties on the reliability of timber structural systems. Compared to other structural materials such as steel and concrete, structural timber has a considerably higher variability of strength both within and between members. LÄS MER
27. Composite Bridges : Innovative ways of achieving composite action
Sammanfattning : The topic of this thesis is steel-concrete composite bridges and innovative ways of achieving composite action. The typical superstructure consists of three main components: the steel girders, the concrete deck slab and the shear connectors. LÄS MER
28. Geometry linking the art of building and the Universe: Geometric patterns on shells and grid shells
Sammanfattning : Geometry links the art of building and the physics of space-time. Mathematical breakthroughs in geometry have led to new ways of designing our structures and our ability to visualise and describe the world, phenomena in nature and the universe. LÄS MER
29. Fatigue Behaviour of RC beams Strengthened with CFRP : Analytical and Experimental investigations
Sammanfattning : Repeated cyclic loading of reinforced concrete (RC) structures such as bridges can cause reduced service life and structure failure due to fatigue even when the stress ranges applied to the structural components are very low. These problems can be mitigated by using fiber-reinforced polymer (FRP) composites to increase the structures’ load carrying capacity and fatigue life or service life. LÄS MER
30. Restraint Effects in Early Age Concrete Structures
Sammanfattning : One of the widespread issues in concrete structures is cracks occurring at early age. Cracks that appear in the young concrete may cause early start of corrosion of rebars or early penetration of harmful liquids or gases into the concrete body. LÄS MER
