Abstract
The aim of this research was experimentally examination the behavior of metal brackets and wood-based panel connections under cyclic loading. For this purpose, different connections were manufactured using three types of brackets (4, 6 and 8 screws) and particleboard (PB) and medium density fiberboard (MDF). The connections were tested under monotonic and cyclic loading according to EN12512 standard and the mechanical properties such as maximum load, impairment of strength, equivalent viscous damping, ductility and the stiffness were determined. The results have shown that in both PB and MDF the brackets with 8 screws provide maximum strength. MDF and PB exhibited similar ductility and most of the connections exhibited viscous damping of less than 20%, which indicates that they have great potential to withstand against cyclic loading. The mechanism of failure was different for connections with 8 screws and connections with 4 and 6 screws.
