Abstract
Concrete-wooden composite beams are structural systems in which an upper concrete flange is connected to a lower timber web. In this study, the concrete-wooden composite beams are produced by using tangential boards of Pinus sp. (dimensions of 100 cm × 5 cm × 2.5 cm). The concrete is reinforced by nail and wire. Concrete-wooden composite beams are made from two types of design. The two arrangement types include one side of the timber and opposite side concrete and, also, it includes the two side timbers and concrete center. Nails (No. 4 and 5) with 3 cm and 5 cm spacing were used for preparing wooden-concrete composite. The nails were hammered about 1.5 cm deep into the boards. After the wooden-concrete composite beams were constructed, their mechanical properties (three-point bending) were measured. The results showed that composite beams with nailing spaces of 3 cm, the concrete height of 5 cm, and the arrangement of two side timbers have been the best mechanical properties. Whereas composite beams with one-sided timber, nailing spaces of 5 cm, and the concrete height of 10 cm have shown the least mechanical strength. The beams of concrete-wooden composite have shown a nonlinear break behavior.
