The Masonry Standards Joint Committee (MSJC) has proposed the  Errata below to the 2008 Building Code Requirements for Masonry Structures (TMS 402-08/ACI 530-08/ASCE-5-08). The MSJC is sponsored by the American Concrete Institute (ACI), the Structural Engineering Institute of the American Society of Civil Engineers (SEI/ASCE), and The Masonry Society (TMS).  In accordance with the rules of The Masonry Society, and consistent with the rules of the other sponsoring organizations, proposed changes to standardized documents must be open for public comment for a period of not less than 45 days.

Comments from the public on this proposed Errata will be accepted through March 31, 2010. Click here to submit comments on this proposed Errata.

1.17.4.3.1 Design of nonparticipating elements — Nonparticipating masonry elements shall comply with the requirements of Section 1.17.3.1 and Chapter 2, 3,4, 5, or Appendix A. Nonparticipating masonry elements, except those constructed of AAC masonry, shall be reinforced in either the horizontal or vertical direction in accordance with the following...

Reason for Errata

During the 2011 MSJC cycle an inadvertent error to the 2008 MSJC was discovered. With the reorganization of Section 1.17, a mistake was made in transcribing the provisions for non-participating elements – Section 1.17.4.3.1 - which accidentally omitted the reference to Chapter 5 in the section.  This was confirmed as an error with the 2008 MSJC Seismic Subcommittee Chair and Secretary. They agreed there was no intention to omit Chapter 5 from this list. This was also confirmed with the 2008 MSJC Main Committee Chair. The minutes for the subcommittee and main committees were searched, again with no reference to this as an intentional action. With this accidental omission from Section 1.17.4.3.1, a conflict has been created within the MSJC as is detailed in the Committee ballot, which can be accessed by clicking here. 

After being sure this was an inadvertent mistake made during the 2008 cycle, we balloted the 2011 Seismic subcommittee to re-insert “Chapter 5” into section 1.17.4.3.1 as errata to the 2008 MSJC.  The work was coordinated with needed MSJC Subcommittees. After a successful Seismic Subcommittee ballot, the item was balloted at the MSJC Main committee and approved. The Technical Activities Committees of The Masonry Society and the American Concrete Institute had an opportunity to review this change when reviewing proposed changes to the next edition of the MSJC Standards. No opposition from TAC was made to the Errata and it is therefore submitted to the Public for comment.
