This course examines the science of wood materials, getting to know the properties of wood, including the structure of wood as an organic material, physical properties of wood, hygroscopic properties of wood, and mechanical properties of wood (direction of fibers and direction of force, elastic modulus, tensile stress, compressive stress , bending stress, shear, moisture content, condition, method and duration of loading). Types and classification of wood (durability, strength and use) commonly used as structural and non-structural materials as well as industry standards for curing and drying, allowable stress. Wood joining tools and wood connections (nail bolts, pegs, adhesives, modern connecting tools and tooth connections), laying construction, beam and pole connections. Structural elements in planning include tension members, compression members (columns with compressive/bending loads), flexible beams, beams supporting moments and normal forces. The appropriate learning model for this course is the direct and cooperative learning method.
