1. Preliminary design and analysis of a pedestrian FRP bridge deck
Sammanfattning : The interest for Fiber Reinforced Polymers (FRP) as an alternative building material is constantly increasing within the building construction sector worldwide. In order to allow for a commercial breakthrough of FRP based building structures, it is necessary to develop design methods that can readily be adopted by bridge engineers. LÄS MER
2. Footbridge Dynamics : Human-Structure Interaction
Sammanfattning : For aesthetic reasons and due to an increased demand for cost-effective and environmentally friendly civil engineering structures, there is a trend in designing light and slender structures. Consequently, many modern footbridges are susceptible to excessive vibrations caused by human-induced loads. LÄS MER
3. Dynamic properties of two pedestrian timber bridges : Experimental and numerical analysis at several stages of construction
Sammanfattning : Pedestrian bridges can beneficially be made from timber in order for our society to reach a sustainable future. This positive development is partly made possible due to advances in engineered wood products (e.g. glued laminated timber) and the possibilities for pre-fabrication of structural parts. LÄS MER
4. Human-structure interaction effect on the dynamic response of footbridges : An analytical and experimental study
Sammanfattning : Lightweight, slender and lightly damped footbridges are often susceptible to HumanInduced Loads (HILs) when pedestrian step frequencies coincide with the naturalfrequencies of the structure. For vertical vibrations, this can compromise the serviceabilitylimit state of the system. LÄS MER
5. Array Processing Techniques for Direction of Arrival Estimation, Communications, and Localization in Vehicular and Wireless Sensor Networks
Sammanfattning : Array signal processing in wireless communication has been a topic of interest in research for over three decades. In the fourth generation (4G) of the wireless communication systems, also known as Long Term Evolution (LTE), multi antenna systems have been adopted according to the Release 9 of the 3rd Generation Partnership Project (3GPP).
