Abstract: A timber structural member includes: a first timber round having a first cooperating longitudinal surface, a second timber round having a second and a third cooperating longitudinal surfaces, and a third timber round having a fourth cooperating longitudinal surface. The first cooperating surface cooperates with the second cooperating surface, and the third cooperating surface cooperates with the fourth cooperating surface. The timber rounds are secured together to form a structurally integral unit in which the first cooperating surface is in contact with the second cooperating surface, and the third cooperating surface is in contact with the fourth cooperating surface, and the first, second and third timber rounds are substantially parallel to each other. The timber rounds are secured to each other by a plurality of spaced fasteners provided at acute and obtuse angles from a longitudinal axis of the structural member and extending through the timber rounds.

Abstract: A timber joist is provided, which includes first and second flanges connected together by a web, the web being structurally integral with the flanges. Both flanges comprise timber poles. The web inserts into the first and second flanges a sufficient distance so as to provide resistance to longitudinal splitting or cracking of the timber.

Abstract: A timber structural member is provided. The structural member includes a first timber round having a first cooperating surface extending longitudinally along the length thereof, and a second timber round having a second cooperating surface extending longitudinally along the length thereof. The first cooperating surface is shaped to cooperate with the second cooperating surface and the two timber rounds are secured together to form a structurally integral unit in which the first cooperating surface is in contact with the second cooperating surface and the first timber round is substantially parallel to the second timber round. The first timber round is secured to the second timber round by a plurality of fasteners spaced along the length of the member, the plurality of fasteners including fasteners provided at both acute and obtuse angles from a longitudinal axis of the structural member.
