Floor and Wall Mounted Equipment (D5)

Design information relative to the anchorage of floor mounted equipment, whether hard mounted or isolated, or wall mounted equipment is provided in this Chapter (D5). Offered are both a technical review of the issues involved as well as more practical installation considerations and options.

This section is recommended reading for Design Professionals or any group responsible for sizing or evaluating the appropriateness of particular restraint devices.

Floor Mounted Section

Floor Mounted Equipment Primer (D5.1.1)
This section provides a technical overview of the forces encountered by all floor mounted equipment in seismic applications.

Forces Transferred between Equipment and Restraints (D5.1.2)
A summary of the details relating to the interface between Floor mounted equipment and the restraint is addressed in this document. Items such as impact and load sharing for different restraint arrangements are discussed.

Attachment of Equipment to Restraints (D5.1.3)
In some cases, the direct connection between equipment and restraint is obvious. In others it is not. Issues that need to be understood relative to this connection are highlighted in this paper.

Attachment of Restraints to the Structure (D5.1.4)
There is a wide range of structures to which restraints can be attached. Variations in these structures as well as in the restraints, can significantly impact the capacity of the system.

Oversized Baseplate Section

Oversized Baseplates - How they work and why to use them (D5.2.1)
When connecting to concrete, the brittle nature of the concrete requires that the load capabilities of the hardware be significantly de-rated. As a result, the restraint device normally has considerably more capacity than does the connection. In these cases, an adapter plate can significantly increase the capacity of the system.

Oversized Baseplates - Capacities and Selection Guide (D5.2.2)
This section offers guidance on selecting an appropriate oversized baseplate for a given application.

Wall Mounted Section

Forces Transferred between Wall Mounted Equipment and Restraints (D5.3.1)
(Under Construction) The addition of gravity loads increases the requirements for restraint hardware in wall mounted equipment. A brief review of the appropriate factors is addressed in this document.

Attachment of Wall Mounted Equipment to Structure (D5.3.2)
(Under Construction) As wall structures are frequently very different from ceiling or floor construction, the detail of equipment attachment must also be adapted. This section addresses this interface.
