16. Plastic design of steel bridge girders
Sammanfattning : This thesis assesses the feasibility of a modified plastic design method for continuous steel or composite bridges with slender I-girders. The feasibility evaluation of the design method is closely connected to the moment-rotation relationship of the I-girders at internal supports. LÄS MER

18. Between square and circle : A study on the behaviour of polygonal steel profiles under compression
Sammanfattning : The present study explores the structural properties of regular convex polygonal cross section (RCPS). Such profiles are commonly used to construct masts and towers, e.g. transmission towers, light poles etc. LÄS MER
19. Reinforcement in Tailor-made Concrete Structures
Sammanfattning : In tailor-made concrete structures of complex geometries, the formability of concrete is an asset. To use this formability in load-bearing structures, the concrete needs to be reinforced. During the past century steel bars were used; however, in recent decades, alternative reinforcement methods have been introduced. LÄS MER
20. Bracing of steel bridges during construction; theory, full-scale tests and simulations
Sammanfattning : A number of steel bridges have suffered lateral-torsional failure during their construction due to their lacking adequate lateral and/or rotational stiffness. In most cases, slight bracing can be of great benefit to the main girders involved through their controlling out-of-plane deformations and enabling the resistance that is needed to be achieved.
