Abstract. Wooden structure restorationwork in historical buildings requires substitution and/or reparation of structural elements. The aim of this investigation is to compare the density, wave velocity, dynamic module, and quality factor intest pieces of solid wood, laminated wood and a multimaterial of P. pseudostrobus. The work hypothesis proposes that dynamic modules of laminated wood and multimaterial laminated wood reinforced with stainless steel mesh are, at least, equal to solid wood. Small dimension test pieces made of solid wood, laminated wood, and multimaterial wood elaborated with the species P. pseudostrobus were prepared. Humidity content and apparent density of wood were determined. Ultrasound tests in radial, tangential, and longitudinal direction were doneand wave velocity, dynamic module, and quality factor were determined. Empiric evidence indicates that wave velocity, dynamic module, and quality factors are different with the three kinds of test pieces. Laminated wood and multimaterial wood characteristics are similar to P. pseudostrobus solid wood; so that the two compound material have good expectations to substitute some pieces that work as resistance elements in wooden structures.
