IBC 2009 to Reference 2008 MSJC and Other TMS Standards
Recently, the International Code Council considered proposed code
changes to the "I-Codes" that include the International
Building Code (IBC) and the International Residential Code
(IRC). Several individuals and industry groups joined The Masonry
Society (TMS) and the Masonry Alliance for Codes and Standards (MACS)
to support comprehensive changes to IBC requirements for masonry.
These changes simplify the IBC provisions so that users can more
easily follow design, construction, and inspection requirements
for masonry. Modifications made by the IBC to referenced standards
will also be more apparent.
The IBC now references the 2008 Masonry Standards Joint Committee's
Building Code Requirements and Specification for Masonry Structures
(TMS 402/ACI 530/ASCE 5 and TMS 602/ACI 530.1/ASCE 6). By referencing
the appropriate standards for masonry materials and construction,
redundancy is removed from the IBC. This becomes important because
the documents are on slightly different cycles and when a change
is made in one, the documents contain conflicting information. In
such cases, it may be unclear which requirement governs. The new
approach reduces the potential for this type of confusion.
In addition, the IBC updated fire resistance requirements to be
consistent with ACI 216-07/TMS 0216-07, Fire Resistance Standard
for Concrete and Masonry Assemblies.
For the first time, the IBC will also reference TMS's new Sound
Transmission Class Rating Standard, which was completed in
2007 (TMS 0302-07).
