21. Flexural Buckling of High-Strength Steel Columns
Sammanfattning : The European standards dealing with design rules and recommendations for steel structures have been under revision in the past years due to the increased use of high-strength steels. High-strength steels popularity increased at a steady pace in the last decades since they allow for more light-weighted solutions than conventional steels. LÄS MER
22. Resistance of polygonal cross-sections : application on steel towers for wind turbines
Sammanfattning : Wind power is considered an efficient alternative for production of electrical energy. One advantage that wind power offers compared to conventional ways of producing energy such as fossil energy and nuclear energy is the low emission of carbon dioxide “CO2” during production of electrical energy.

23. Patch loading : resistance of longitudinally stiffened steel girder webs
Sammanfattning : In most cases, longitudinal stiffeners increase the resistance of steel girder webs subjected to concentrated forces, commonly referred to as patch loading. During the last three decades, a number of experimental investigations have been undertaken in all over the world in this regard. LÄS MER

25. Load-Carrying Capacity of Steel Girders and Panels with Thin-Walled Trapezoidally Corrugated Webs
Sammanfattning : This thesis concerns the load-carrying capacity of steel girders and panels with thin-walled trapezoidally corrugated webs. Computer-based numerical methods are used as a tool and emphasis is placed on various parametric studies, covering geometric parameters, initial imperfections, material strain-hardening models, loading types and loading positions, and so forth.
