Chapter 21supercedes Army TM 5-809-3, NAVFAC DM-2.9, AFM 88-3,Chapter 3, Masonry Structural Design for Buildings. Give special attention to control cracking in concrete masonrystructures using the guidance contained in Tables 1-2 and Table1-3. Because the Masonry Society has a waiver for use of metricproducts, brick and concrete masonry units (CMU) are normallynot available in metric sizes.11HEARTLAND ENGINEERS
