The pressure of granular mass on container bottom has been experimentally investigated in vertically vibrated granular beds. Pulse signals are found of the pressure, and the pulse strength undergoes subharmonic bifurcations controlled by the scaled vibration acceleration. Condensed state of particles is observed at the bed bottom, in which the particles are closely packed, with small free path, and move like a bulk block.
