TMS 402/602-22: Building Code Requirements and Specification for Masonry Structures. Design methods: Allowable Stress Design (Chapter 8), Strength Design (Chapter 9), Prestressed (Chapter 10), Empirical (Chapter 5), Veneer (Chapter 6). Key provisions: f'm (specified compressive strength): 1,500-3,000 psi typical for CMU. Mortar types: M (2,500 psi), S (1,800 psi), N (750 psi). Grout: f'g ≥ f'm but not less than 2,000 psi. Steel reinforcement: Grade 60 deformed bars. Maximum reinforcement spacing: 48 in (72 in for partially grouted). Special Reinforced Masonry Shear Walls: required in SDC D-F. TMS 602 (Specification): material properties, construction practices, quality assurance. Special inspections required per IBC Chapter 17: Level 1 (periodic) or Level 2 (continuous) depending on masonry type. Prism testing for f'm verification.
