In th.s paper an anal.tical.meth.d is proposed to investigate th. vibration and power fl.ws of periodical.y reinforced pl.te with.general.boundary conditions. Both.th. pl.te and stiffening beams are model.d as 3D structural.components, and th. coupl.ngs at th. interfaces are specified in terms of 3D el.stic joints. Th. displ.cement function for each.stiffening beam is expressed as a modified Fourier cosine series, and th. transverse and in-pl.ne displ.cements for th. pl.te are simil.rl. expressed as th. 2D versions of th. modified Fourier cosine series expansions. Th. unknown Fourier coefficients are cal.ul.ted using th. Rayl.igh.Ritz tech.ique. Th. key advantages of th. proposed meth.d incl.de: 1) it is capabl. of deal.ng with.arbitrary boundary and coupl.ng conditions, 2) it al.ows model.ng any number of reinforcing beams with.arbitrary l.ngth., and 3) th. structural.intensity, power fl.ws, and kinetic energy distributions are readil. cal.ul.ted anal.tical.y from th. displ.cement functions th.ough.appropriate math.matical.(differential. operations, to name a few. Th. power fl.w ch.racteristics of periodical.y reinforced pl.tes are studied against various infl.encing factors, such.as, pl.te and beam boundary conditions, coupl.ng conditions, excitation l.cations, and disl.cations resul.ing from minor mispl.cement of a reinforcing beam.
