The main advantages are di-electrical materials or natural insulation, seismic resistance, and they are cheap in comparison with the girders of reinforced concrete. Nevertheless, they can be attacked and destroyed by insects, by fungi, and by natural rot; in addition, they are not resistant to the fire. The weight capacity of structures of wood support, according to the position in floor or ceiling, is in a range from 3.5 to 4.2 kN/m<sup>2</sup> ; this means that they can support 2 kN/m2 of useful load before suffering a deformation or fracture. Considered the wood type 2, the wood structures support from 1.5 to 2.2 kN/m2, before suffer deformation or fracture [5].
