Sažetak
Vibrations of timber floors in residential buildings and timber bridges under vehicle and pedestrian loading are a subject of research for the new version of the European norms for the design of timber structures. One of the topics that is least understood is the principle of damping in timber beams which are one of the main structural elements in timber floors and bridges. Overall dampingξin beams can be described as a sum of material (internal) dampingξintand structural damping. Structural damping depends on connections in the structural system (floors, bridges) and values can only be found using numerical computation in a finite element software. On the other hand, material damping depends on the material properties, internal friction and the level of stress. There are various models which are used for modelling internal damping but here the emphasis is on hysteretic damping model. The basics of its use in modelling damping comes from the result that energy dissipation per cycle of vibration is a consequence of internal friction known as material hysteresis. The dissipated energy is independent of frequency and using the hysteretic damping factor the SDOF equation for vibrations can be solved.
