Seismic Restraint Manual Guidelines for Mechanical Systems (45 Day Public Review)

This fourth edition of the Seismic Restraint Manual: Guidelines for Mechanical Systems has been updated to conform to the International Code Council for anchorage capacities.

All Seismic Reinforcement Brace (SRB) tables have been updated to provide users with more SRB options including the addition of new tables. Refreshed instructions for using the guidelines. Chapter 9 expansion anchor tables have been updated with new tables. New Appendix B to assist in determining the weight of the duct or pipe to be braced. Many new and updated details have been included to align with changes made throughout the document.

Rectangular Industrial Duct Construction Standards (45 Day Public Review)

This third edition of the Rectangular Industrial Duct Construction Standards includes many of the same assumptions as the first and second edition with a number of added features.

Expanded panel pressure capacity tables and stiffener spacing options for carbon and coated steel, stainless steel and aluminum to accommodate larger ducts and allow for added duct construction options. Stainless steel panel pressure capacity tables added for Class 2, 3 and 4 applications with additional stainless steel operating temperature design capabilities. Laboratory testing, physical testing and data analysis on rectangular duct was completed to further evaluate side wall shear capacities of local buckling to those already introduced in the first and second edition.
