wood-concrete composites are floor and deck systems which comprise of a concrete slab integrally connected to wooden beams or a laminated wooden slab . we have also developed expertise in analyzing and designing these systems . asce practice periodical on structural design and construction., 13(4), pp. 167- .

designer towards the most appropriate and cost effective choice of floor system. the range of steel based floor systems is presented in general terms, with the advantages .
composite wood members are becoming more prevalent in structural system design, and they are expected to become even more important as demand for forest products continues to force improved utilization of available fiber resources. prefabricated wood i-beams represent an efficient use of materials .
beams. design guide. by jim destefano, p.e. flitch plate beams are composite mem- bers which combine the strength and stiffness of structural steel with the ver- satility of wood. a flitch plate is a steel plate that is sandwiched between pieces of framing lumber and bolted together. they are used in a similar .

wooden composite beams are produced by using tangential boards of pinus sp. (dimensions of 100cm 5 cm 2.5cm). 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 .
