Szukana fraza: [Abstract = The paper concerns the rheological bending problem of wooden beams reinforced with embedded composite bars. A theoretical model of the behaviour of a multi\-layered beam is presented. The component materials of this beam are described with equations for the linear viscoelastic five\-parameter rheological model. Two numerical analysis methods for the long\-term response of wood structures are presented. The first method has been developed with SCILAB software.]
