The article presents the results of experimental investigation in regard of the deformability properties of pre-stress-laminated fiber timber slabs characterized with various combinations of design parameters at bending. Evaluation of deflection at all the points on the slab was made by means of the continuous laser scanning method. There was carried out a complex multi-factorial experiment. As a result, there was obtained a mathematical regression model describing the structure bending process. There has been proved the influence of the combination of such design parameters of the stress-laminated timber slab as its width, the spacing of pre-stressed rods and the effort of pre-stressing on the deformability properties.
