  • Publication number: 20190218795
    Abstract: A building assembly, for use in a floor and/or ceiling of a building, consisting of a solid wood or mass timber structural panel layer, a lightweight panel layer, and an acoustically absorptive solid volume material layer between the solid wood or mass timber structural panel layer and the lightweight panel layer to provide a separation of an air-borne acoustic vibration or a separation of an impact- or structure-borne acoustic vibration between the lightweight panel layer and the solid wood or mass timber structural panel layer.

  • Patent number: 10267053
    Abstract: A building wall comprises a shear wall panel having a horizontal bottom edge, a bottom left corner, and a bottom right corner. The wall sits atop a horizontal base support located under the horizontal bottom edge of the shear wall panel. A tie-down couples the shear wall panel to the base support at a central point along the horizontal bottom edge of the shear wall panel such that the shear wall panel rocks under horizontal forces. Toe crushing elements are situated under the bottom corners of the shear wall panel. The bottom corners of the shear wall panel compress the toe crushing elements as the shear wall panel rocks about the tie-down under horizontal forces.

  • Patent number: 10081961
    Abstract: A building wall includes a first shear wall panel having a horizontal bottom edge and a right vertical edge, a horizontal base support located under the horizontal bottom edge of the first shear wall panel, and a first tie-down that couples the first shear wall panel to the base support at a central point along the horizontal bottom edge of the first shear wall panel such that the shear wall panel rocks under horizontal forces. The wall further includes a second shear wall panel in plane with and adjacent to the first shear wall panel, the second shear wall panel having a horizontal bottom edge and a left vertical edge. The horizontal base support further is located under the horizontal bottom edge of the second shear wall panel, and a second tie-down couples the second shear wall panel to the base support at a central point along the horizontal bottom edge of the second shear wall panel such that the second shear wall panel rocks under horizontal forces.
