Masonry Structures With Box Behavior . The masonry walls are 30 feet high on all sides, with the upper 2 feet being a parapet. For example, the toothing between perpendicular walls, the junction with horizontal diaphragms, the interaction with adjacent buildings, etc., can sensibly influence the structural response of masonry buildings (Tondelli et al., 2012). (13 mm) diameter bolts spaced at a maximum of 4 ft (1.2 m), or with other bolts and spacings that provide equivalent anchorage. Building Code Requirements and Specification for Masonry Structures contains two standards and their commentaries: Building Code Requirements for Masonry Structures designated as TMS 402-16 (and formerly designated as TMS 402/ACI 530/ASCE 5) and Specification for Masonry Structures designated as TMS 602-16 (and formerly designated as TMS 602/ACI 530.1/ASCE 6).
