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 seismic shim for electronic equipment comprises a base comprising at least a first hole through the base, wherein the first hole is configured to receive a first fastener, and an extension portion extending from the base. The extension portion is perpendicular to the base and comprises at least a second hole through the extension portion, wherein the second hole is configured to receive a second fastener. The seismic shim also comprises a first gusset and a second gusset disposed between the base and the extension portion. The second gusset is spaced apart from the first gusset. The seismic shim is configured for anchoring to an underlying floor structure via the first fastener inserted through the first hole, and is configured for attachment to a surface of the electronic equipment via the second fastener inserted through the second hole.

A tuned liquid damper, including a first outer housing having two ends, the first end being open to the atmosphere and the second end being connected by a conduit to a gas-filled second outer housing. The conduit may be adapted to allow gas flow between the second end and the second outer housing. The tuned liquid damper may also include first and second membranes, each attached to the inside of the first outer housing, and a sealed compartment within the first outer housing defined by the first and second membranes. The sealed compartment may be at least partially filled with a liquid, which prevents gas flow through the first outer housing from the first end to the second end.

A vibration absorption device for acoustic insulation for a building structure comprises an absorbent cushion and a vibration isolation cushion. The building structure is selected from a ceiling structure, a floor structure and a partitioning structure separating two adjacent building compartments or a building compartment and the external environment. The absorbent cushion comprises sound absorbing material and the vibration isolation cushion comprising vibration isolation material. The vibration isolation cushion overlies and is laminated to the absorbent cushion. The vibration isolation cushion is rigid relative to the absorbent cushion. The absorbent cushion is supple relative to the vibration isolation cushion. The vibration absorption device is mountable to the building structure, to isolate vibrations and to provide acoustic insulation between the two separated and adjacent building compartments.

An attachment device for securing a non-structural component of a building to a structural component of the building includes a non-structural component holder defining a receiving space configured to receive the non-structural component to couple the non-structural component to the attachment device. The non-structural component holder applies generally no compressive force against the non-structural component when the non-structural component is disposed in the receiving space so that the non-structural component is free to move relative to the non-structural component holder. A stop is configured to be secured to the non-structural component. The stop is configured to engage the non-structural component holder to inhibit movement of the non-structural component relative to the non-structural component holder when the stop and non-structural component holder are secured to the non-structural component.
