Reduced and test-data correlated FE-models of a large timber truss with dowel-type connections aimed for dynamic analyses at serviceability level

The rise of wood buildings in the skylines cities forces structural dynamic and timber experts to team up solve one new civil-engineering challenges, namely comfort at higher levels, light weight buildings, with respect wind-induced vibrations. Large laminated structures mechanical joints are exposed turbulent horizontal excitation most wind energy blowing around lowest resonance frequencies 50 150 m tall buildings. Good knowledge spatial distribution mass, stiffness damping is needed predict mitigate sway lighter, flexible This paper presents vibration tests reductions a detailed FE-model truss dowel-type connections leading models that will be useful for engineers. also enable further investigations about parameters slotted-in steel plates dowels governing dynamical response trusses.
