Abstract: 

In this survey, physical and mechanical properties of Quercus Castaneaefolia in Golband site of Noshahr were measured in green moisture content. Based on ASTM Standard, results indicated that the most important mechanical properties of the above-mentioned species of oak with specific gravity 0.618 (based on dry weight & green volume) and volumetric shrinkage 13%. include MOR (744 kg/cm 2), MOE (82556 kg/cm 2), work to maximum load in bending (56 kj/m 3), maximum stress in compressive strength parallel to grain (317 kg/cm 2), stress at proportional .limit in compressive stress perpendicular to grain (112 kg/cm 2), maximum stress in shear strength parallel to grain (109 kg/cm 2), maximum stress in tensile strength perpendicular to grain (63 kg/cm 2), toughness strength (3.34 kg.m), cleavage (90 kg/cm). In addition, hardness of tangential, radial and cross-section surfaces were respectively 642. 661, 665kg, and withdrawal load in these surfaces were 54. 62 and 40 kg/cm. Moreover, the impact of the tree height well as geographical direction of the site on the mechanical properties of oak were investigated.
