Suspended Equipment (D10)

This section comprehensively addresses the restraint of Suspended Equipment in seismic applications. It is extremely practical in nature. It avoids the basic sizing of components (which is explained in Chapter D4) and focuses on layout and hardware issues.

This chapter is recommended reading for Installation contractors, design support for contractors and field inspection personnel.

Seismic Forces Acting on Suspended Equipment (D10.1)
This section provides a brief overview of the forces encountered by suspended equipment exposed to seismic forces and how they generate loads in restraint systems.

Basic Primer for the restraint of Suspended Equipment (D10.2)
This section addresses different kinds of by suspended equipment, variations between them and provides some general direction in getting started with a restraint plan.

Pros and Cons of Struts versus Cables (D10.3)
While Struts and Cables are often used to perform the same restraint function and because they appear similar to the casual observer, there are significant differences between them that need to be accounted for in the field. This section addresses these issues.

Suspended Equipment - Definitions and Locations (D10.4.1)
Basic installation "Rules" along with basic definitions of terms used in later sections of this manual make up this section of the manual.

Suspended Equipment Arrangements (D10.4.2)
Illustrated here are a wide range of options for the installation of Restraints suitable for use on suspended equipment.

Attachment Details - Transferring Forces (D10.5.1)
A key element in the effectiveness of a restraint is the details of the connection. Basic parameters required to ensure that these connections are appropriate for seismic applications are included in this paper.

Attachment Details - Cable Clamps (D10.5.2)
There are several end connection details that are suitable for cable restraints. Both appropriate and inappropriate connections are identified in this section along with proper installation techniques.

Attachment Details - Suspended Equipment (D10.5.3)
The connection between the cable or strut and the equipment can be accomplished in a wide variety of ways and through the use of a wide variety of hardware. A wide variety of acceptable arrangements applicable to a broad variety of possible applications are shown and discussed in this section.

Attachment Details - Attachment to Structure (D10.5.4)
Similar to the connection between the cable or strut and the suspended equipment is the connection between the cable or strut and the structure. Cautions are required to ensure that the structure is not weakened by the connection and that the connection is adequate to transfer the design load. As in the section above, this segment illustrates a wide variety of acceptable arrangements that can accomplish this feat.

Connection options for Awkward Situations (D10.6)
Virtually every application will have situations where the basic connection arrangements won't fit or simply are not suitable. This section illustrates several typical "Awkward" situations and offers guidance on possible configurations to incorporate restraints in these areas.
