Predicting Damping of Semi-Rigid Glued T-Beams
Keywords:
Strain, energy, damping, beams, composite, nonrigid, floorsAbstract
A theoretical model for predicting damping in composite wood T-beam is provided. The formulation is based on energy dissipation due to relative slip at the interface of the flange and joist. A loss factor parameter as obtained from stress-strain relationship of elastomeric adhesive has been introduced into the formulation. Damping computed from experimental tests is found to about 5% to 8% compared to theoretical values of 4.5% to 6.5%.References
