The subject of this diploma thesis is the study of strength properties of oak and oak-poplar laminated veneer lumber (LVL) in static bending prior to exposure to cyclic bending as well as LVL that have undergone cyclic bending. The main aim is to evaluate the impact of cyclic bending on mechanical properties of laminated wood. The thesis briefly documents characteristics, production and use of laminated wood in number of industries. Moreover, it describes materials used for the manufacture of LVL as well as the process of test specimen production. The cyclic bending was executed at 1,000 cycles, 2,000 cycles, 3,000 cycles and 4,000 cycles. During the testing we studied the differences between the strength properties of the LVL exposed to cyclic bending and the LVL that was not exposed to cyclic bending in the cyclic and skid testing. Based on the studied extent of laminated wood cyclic bending we can conclude that its impact on the selected mechanical properties – solidity and modulus of elasticity – was not significant.
