Effects of Strongbacks and Strappings on Vibrations of Timber Truss Joist Floors

Table 1

Physical and mechanical properties of the adopted oriented strand boards (OSBs).

Thickness (mm)	MOR∥ (MPa)	MOR⊥ (MPa)	MOE∥ (MPa)	MOE⊥ (MPa)	Density (kg/m^3)
15	35.1	20.5	4280	2080	650
18	35.3	22.6	5240	2400

Note. MOE and MOR are the modulus of elasticity and the modulus of rupture, respectively; ∥ and ⊥ denote parallel (major strength direction) and perpendicular (minor strength direction) to the length direction, respectively.
