The 2005 Building
Code Requirements for Masonry Structures, Specification for Masonry
Structures, and Commentaries are now available in paper
or CD versions. Information in the code has been substantially revised
to keep pace with new technology. Several sections have been updated
since the previous edition and new topics are included as well.
Major Updates to the 2005 MSJC Masonry Code
- Strength design procedures for Autoclaved Aerated Concrete (AAC)
Masonry. (Appendix A) This is a new topic for the code. AAC units
are lightweight, insulating units.
- Complete revision in Prestressed Masonry design philosophy to
a strength design basis with service load checks.
- Revised maximum reinforcement limits for Strength Design.
- Harmonized splice length requirements for Allowable-stress Design
and Strength Design
- Clarification on limits for empirical design in areas with high
wind.
Responsible Organizations
The Masonry Code is a consensus design standard developed by the
Masonry Standards Joint Committee, or MSJC. This is a joint committee
of three organizations: The Masonry Society (TMS), American Concrete
Institute (ACI), and the Structural Engineering Institute of the
American Society of Civil Engineers (ASCE).
 Each
assigns its own code number to the documents, which are the building
code and specification with commentaries. Hence the designations
Building Code Requirements for Masonry Structures (ACI
530-05/ASCE 5-05/ TMS 402-05), Specification for Masonry Structure
(ACI 530.1-05/ASCE 6-05/ TMS 602-05), Commentary on Building
Code Requirements for Masonry Structures (ACI 530-05/ASCE 5-05/
TMS 402-05), and Commentary on Specification for Masonry Structures
(ACI 530.1-05/ASCE 6-05/ TMS 602-05).
