1. Vibration Frequencies as Status Indicators for Tensegrity Structures
Sammanfattning : Applications of vibration structural health monitoring (VHM) techniques are increasing rapidly. This is because of the advances in sensors and instrumentation during the last decades. VHM uses the vibration properties to evaluate many civil structures during the design steps, building steps and service life. LÄS MER
2. Vibration-based Assessment of Tensegrity Structures
Sammanfattning : Vibration structural health monitoring (VHM) uses the vibration properties to evaluate many civil structures during the design steps, building steps and service life.The whole function, expressed by stiffness and frequencies of tensegrity structures are primarily related to the level of pre-stress.

3. Stiffness and vibration properties of slender tensegrity structures
Sammanfattning : The stiffness and frequency properties of tensegrity structures are functions of the pre-stress, topology, configuration, and axial stiffness of the elements. The tensegrity structures considered are tensegrity booms, tensegrity grids, and tensegrity power lines.A study has been carried out on the pre-stress design. LÄS MER
4. Stress-laminated-timber bridge decks subjected to ultimate loads
Sammanfattning : Stress-laminated-timber (SLT) bridge decks are a satisfactory alternative to conventional short-span bridges in terms of cost and performance. SLT decks are made from several deck laminations positioned side by side. LÄS MER
5. Power dissipation in car tyres
Sammanfattning : Traffic is a major source of green house gases. The transport field stands for 32 % of the energy consumption and 28 % of the total CO2 emissions, where road transports alone causes 84 % of these figures. LÄS MER
