Building Code Requirement for Masonry Structures (ACI 530-95/ASCE 5-95/TMS 402-95), Specification for Masonry Structures (ACI 530.1-95/ASCE 6-95/TMS 602-95), Commentary on Building Code Requirements for Masonry Structures (ACI 530-95/ASCE 5-95/TMS 402-95), and Commentary on Specification for Masonry Structures (ACI 530.1-95/ASCE 6-95/TMS 602-95) is a joint effort of the American Concrete Institute, the American Society of Civil Engineers, and The Masonry Society. The Code covers the design and construction of masonry structures, while the Specifications is concerned with the quality, inspection, testing and placement of materials used in construction. Some of the topics covered in the Code are: definitions, analysis and design, strength, axial loads, shear, beams, and seismic design. On the other hand, the bonding and anchoring of masonry, and the placement of grout and reinforcements. Since the Code is written as a legal document and the Specification as a master specification required by the Code, the two Commentaries present background details, committee considerations, and research data used to develop the Code and Specifications.
