The present invention provides a building comprising a foundation; a wall supported by the foundation; and trusses supported by the wall. A plurality of hold down assemblies connects at least some of the trusses directly to the foundation. Each hold down assembly comprises an anchor; a tie-rod connected to the anchor; a bearing plate operably associated with an end portion of an associated truss for transferring load to the tie-rod; and a fastener securing the tie-rod to the bearing plate, thereby tying the associated truss directly to the foundation.

A hold down system for a building wall comprises a first rigid member and a second rigid member, the second rigid member being vertically spaced apart from the first rigid member, the first rigid member is supported on a horizontal member of a stud wall, the first and second rigid members including first and second openings, respectively; a tie-rod with a lower end portion for being anchored to an anchorage, the tie-rod extending transversely through the first and second openings, the tie-rod dividing the first and second rigid members into a first lateral section on one side of the tie-rod and a second lateral section on a diametrically opposite side of the tie-rod; first support and second support disposed between the first and second rigid members, the first support being disposed in the first lateral section, the second support being disposed in the second lateral section, the tie-rod extending through the first and second rigid members outside of the first support or the second support; and a nut threaded to the tie-rod, the nut exerting pressure on the second rigid member to place the tie rod under tension loading, the tension loading is transferred by the second rigid member to the first and second supports to subject the first and second supports to compression loading, thereby causing the first rigid member to press on the horizontal member of the stud wall via the first and second lateral sections of the first rigid member, thus distributing the compression loading.

A building includes a foundation; a stud wall disposed above the foundation; the stud wall including a bottom plate, first and second studs extending from the bottom plate, and a top plate operably attached to the first and second studs; third and fourth studs operably attached to the respective first and second studs, the third and fourth studs including respective bottom ends; a first cross member disposed on the bottom plate, the bottom ends of the third and fourth studs bearing on the first cross member, the first cross member is made of metal; a second stud wall disposed above the first stud wall; and a tie rod having one end operably connected to the foundation, the tie rod extending through the first cross member and operably attached to the second stud wall.

A hydraulic expandable connector for taking up a slack in a tie rod in a hold-down system includes an inner cylindrical body disposed within an outer cylindrical body; a first actuation spring operably attached to the inner cylindrical body and the outer cylindrical body to urge relative motion between the inner cylindrical body and the outer cylindrical body such that the connector expands axially to take up the slack; a first chamber and a second chamber disposed between an outer wall surface of the inner cylindrical body and an inner wall surface of the outer cylindrical body; a first passageway communicating between the first chamber and the second chamber; and a valve operably disposed in the first passageway in an open position when the connector expands and a closed position when the connector is subjected to an axial load.

A device for compensating for the natural shrinkage of building materials includes a hinged expander mounted on an elongate base plate. The base plate includes a plurality of spaced apart teeth on each longitudinal end that define a notch between each pair of adjacent spaced teeth. The hinged expander included two leafs that are joined at an apex in a hinged relationship. Each leaf has an outer edge configured for receipt within a notch in the base plate. Apex is biased in a direction away from the base plate. The teeth prevent outward movement of the leaf edges while permitting inward movement. The base plate is securely fastened to a first building member. A fastener is longitudinally fixed relative to a second building member and the apex of the hinged expander but not fixed longitudinally relative to the base plate and first building member.

A shrinkage compensating device for seismic restraint in wood building construction combines a spring-operated take-up device (TUD) with a ratcheting split nut. The split nut, attached to or formed as part of a rotatable component of the TUD, acts as the securing nut for the TUD and allows the TUD with the split nut to be slipped over the top of a threaded rod and pulled down along the rod into place against a structural member. Several forms of attachment of the split nut to the spring-operated TUD are disclosed, as is a simplified rotatable split nut version.

A hold down system for a building wall comprises a first rigid member and a second rigid member, the second rigid member being vertically spaced apart from the first rigid member, the first rigid member is supported on a horizontal member of a stud wall, the first and second rigid members including first and second openings, respectively; a tie-rod with a lower end portion for being anchored to an anchorage, the tie-rod extending transversely through the first and second openings, the tie-rod dividing the first and second rigid members into a first lateral section on one side of the tie-rod and a second lateral section on a diametrically opposite side of the tie-rod; first support and second support disposed between the first and second rigid members, the first support being disposed in the first lateral section, the second support being disposed in the second lateral section, the tie-rod extending through the first and second rigid members outside of the first support or the second support; and a nut threaded to the tie-rod, the nut exerting pressure on the second rigid member to place the tie rod under tension loading, the tension loading is transferred by the second rigid member to the first and second supports to subject the first and second supports to compression loading, thereby causing the first rigid member to press on the horizontal member of the stud wall via the first and second lateral sections of the first rigid member, thus distributing the compression loading.
