ABSTRACT:
A method for securing a building to a foundation provides hold-down units that perform double-duty by acting as a compressive load on a floor immediately therebelow due to the force of a seat or base portion thereof. Meanwhile, a flange portion of each hold-down device extends upward to fasten to the upright members in an upper floor applying tension thereto. Thus, an anchoring rod extending through multiple floors of the shear walls may reduce the number of total hold-down devices by an amount approaching half that otherwise required. Likewise, the number of more expensive, automatic, take-up devices used is reduced by approximately half.
