ABSTRACT
156Anchorage provides the connective interface between masonry and materials, such as steel and timber. Common applications include the connection of wood top plates and ledgers, headed stud anchors on embedded plates to make a welded connection illustrated in Figure 8.1, and anchors for veneer support angles. Anchors consist of two parts: internal and surface elements. Internal components engage the masonry and include anchor bolts, headed studs, or drilled anchors. Surface components consist of plates, angles, and nuts that complete the connection.
We use Section 9.1.6 of Building Code Requirements for Masonry Structures, TMS 402 1 for strength design of masonry anchorage. This covers the vast majority of conditions, but does not consider fatigue due to vibrating equipment, traffic loads, impact, or blast loads. Our goal for this chapter is to become familiar with design requirements and gain an understanding of what variables influence anchorage design.
