Higher and higher timber buildings are built today where stabilization against wind, oscillations and vibrations become more critical in design. Due to the low density of wooden structures they can be exposed to large lateral displacements. Wind can also create oscillations and vibrations of the building and cause discomfort for the residents. The stiffness and the mass of the building will affect the dynamic behavior of it with increasing number of floors.
The focus in this project is to study:
- At what height will static displacements and dynamic movements be important design criteria? When do we need special design solutions to meet the requirements regarding oscillations and vibrations?
- What types of building systems are suitable for different building heights? And how can different building systems combine?
The project is performed through finite element modeling, hand calculations and collection of test data. The project is financed by Sweco Structures AB and TräCentrum Norr.
