Masonry Magazine September 2010 Page. 35
For many years, the industry has followed the standard veneer wall construction of the ACI 530/ASCE 5/TMS 402, and this excerpt, "the anchor must be capable of withstanding 100# load in tension and compression without deforming or developing play in excess of 0.05," has been used to describe the requirements of an anchoring system. But, as you may have already guessed, the days of "picking an anchor out of a catalog" are quickly becoming a thing of the past. The requirements for every project need to be reviewed when selecting a suitable anchoring system to meet the demands of today's masonry walls. Strength, movement capability, adjustability, and air barrier interface are all items that need to be considered.
With all of the components involved in the modern masonry wall, perhaps the most important factor to consider is the compatibility of all elements going into the wall assembly. With so many anchor types, air and vapor barrier materials, and flashing products on the market, it is becoming increasingly difficult for both architects and contractors to determine what constitutes a high-quality assembly. As the industry evolves, "complete systems" with single-source warranties should become popular, similar to the roofing industry with independent testing and compatibility requirements for all components.
