The new non-consolidation of isolated structure proposed for low-rise and multi-storey buildings structure and the non-consolidation bearing were conducted in the paper. The static tests of viscoelastic material and the non-consolidation bearing were performed in order to study mechanical properties of viscoelastic material and the non-consolidation bearing. Experimental results show that the two viscoelastic material have similar energy dissipation capacity, and the vertical stiffness is great and the vertical energy dissipation capacity is limited of the bearings. Experimental results also show the bearing the horizontal hysteresis curve is a double cone, and the equivalent damping ratio is 15% to 35% at different parameters.
