1. Acoustical Characteristics of Aircraft Panels
Sammanfattning : A deterministic approach based on a modal expansion and modal receptance method has been developed to evaluate the airborne sound insulation of aircraft panels with stringer and ring frame attachments. Furthermore, this method was extended to predict the noise radiation of stiffening panel subjected to TBL excitation. LÄS MER
2. Sound transmission through aircraft panels
Sammanfattning : .... LÄS MER
3. 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
4. Plate buckling resistance : patch loading of longitudinally stiffened webs and local buckling
Sammanfattning : Incremental launching of steel bridges is a demanding undertaking, on the erection site as well as on the designers desk. Not seldom, the structure itself is during the launching subjected to high concentrated forces on the lower flange when passing over the launching shoe or a intermediate support (e.g. column).

5. Innovative structural details using high strength steel for steel bridges
Sammanfattning : The use of high strength steel has the potential to reduce the amount of steel used in bridge structures and thereby facilitate a more sustainable construction. The amount of steel and what steel grade that can be used in bridge structures and other cyclic loaded structures are often limited by a material degradation process called fatigue. LÄS MER
