Strength Design of Anchor Bolts

In masonry construction, anchor bolts are most commonly used to anchor roof or floor diaphragms to masonry walls. As shown in Fig. 5.26, vertically oriented anchor bolts can be placed along the top of a masonry wall to anchor a roof diaphragm resting on the top of the wall. Alternatively, horizontally oriented anchor bolts can be placed along the face of a masonry wall to anchor a diaphragm through a horizontal ledger. In these applications, anchor bolts are subjected to combinations of tension and shear. In this section, the behavior of anchors under those loadings is discussed, and 2008 MSJC strength design provisions are reviewed.
