Abstract

In this study, three geographical sites in north of Iran with the elevations of 40, 500 and 1000m were selected. In each site 10 trees, totally 30 trees were randomly marked and felled. From each tree, three 5 cm thick discs at the heights of 1.30,3.00 and 6.00m were cut and the tree trunk was converted into three logs and was carried to the sawmill. Physical and MECHANICAL PROPERTIES including specific gravity; static bending (MOE and MOR), compression parallel to grain, compression perpendicular to grain, shear parallel to grain, tension perpendicular to grain (maximum stress), cleavage resistance, hardness (tangential, radial and cross section), impact resistance, were performed according to ASTM standards. Physical and mechanical tests results indicated that at the elevation of 1000m all MECHANICAL PROPERTIES except that static bending and compression parallel to grain increase with the Increased in density, while at the elevation of 40m they all dealing. The differences between the three sites were significant at 1% significant level. At 500m altitude all of the wood mechanical parameters were good but at in 40m due to the reduction of specific gravity, strength of wood decreased and application of wood was limited.
