Seismic Forces Acting on Curb Mounted Equipment (D6)

Design information relative to the connection of curb mounted equipment, whether hard mounted or isolated, is provided in this Chapter (D6). It offers a technical review of curbs and equipment/curb interfaces as well as more practical installation considerations.

This chapter is recommended reading for Design Professionals or any group responsible for sizing or evaluating the appropriateness of curbs and curb mounted restraint devices and curbs themselves. The is also more practical guidance as to how to increase the capacity of non-seismically rated curb assemblies.

Seismic Forces Acting on Curb Mounted Equipment (D6.1)
This section provides a technical overview of the forces encountered by curb mounted equipment in seismic applications.

Sheet Metal Curb Section

Basic Primer for Sheet Metal Curbs (D6.2.1)
An overview of curbs and curb issues is the key goal of this document. It offers the reader a basic understanding of the issues involved.

Attachment of Equipment to Sheet Metal Curbs (D6.2.2)
Making structural connections to sheet metal structures is often difficult. It is the intent of this paper to offer make the reader aware of key factors needed to have a successful installation.

Transferring Seismic Forces through Sheet Metal Curbs (D6.2.3)
Methods of increasing the seismic capacity of unrated sheet metal curbs are addressed in this document.

Attachment of Sheet Metal Curbs to the Building Structure (D6.2.4)
Similar to the equipment connection, making structural connections to sheet metal structures is often difficult. It is the intent of this paper to offer make the reader aware of key factors needed to securely anchor curbs to the supporting structure.

Limitations of Sheet Metal Curbs in Seismic Applications (D6.2.5)
Guidance as to when a sheet metal curb may be appropriate and when it isn't is covered in this paper.

Rules for Using Sheet Metal in Seismic Applications (D6.2.6)
This document is a summary of the previous (D6.2) documents in this chapter offering basic guidance without going into detail.

Structural Curb Section

Basic Primer for Structural Curbs (D6.3.1)
(Under Construction) An overview of curbs and curb issues is the key goal of this document. It offers the reader a basic understanding of the issues involved.

Attachment of Equipment to Structural Curbs (D6.3.2)
(Under Construction) Access, weatherproofing, and secure attachment all make connecting equipment to curbs more difficult than it would be in an interior environment It is the intent of this paper to offer make the reader aware of key factors needed to have a successful installation.

Transferring Seismic Forces through Structural Curbs (D6.3.3)
(Under Construction) Methodologies used to maximize the seismic capacity of structural curbs are addressed in this document.

Attachment of Structural Curbs to the Building Structure (D6.3.4)
(Under Construction) Because of the long narrow footprint of each of the curb walls, making structural connections to the parent structure is often difficult. It is the intent of this paper to offer make the reader aware of key factors needed to securely anchor curbs to the supporting structure.

Limitations of Structural Curbs in Seismic Applications (D6.3.5)
(Under Construction) Guidance as to when structural curbs are suitable and when they are not, are covered in this paper.

Rules for Using Structural Curbs in Seismic Applications (D6.3.6)
(Under Construction) This document is a summary of the previous (D6.3) documents in this chapter offering basic guidance without going into detail.
