This section of the 1935-miami-dade-building-code details regulations for structural steel, foundations, and masonry walls.
Structural Steel and Iron
Chapter 27 establishes quality standards referencing american-society-for-testing-materials specifications (A9-33, A27-24, A48-32T) for structural, cast steel, and cast iron (p. 206). It defines allowable unit stresses for tension, compression, bending, and shear, including specific formulas for column buckling and beam stability (p. 207-208). The code mandates that trusses be preferably riveted rather than pin-connected (p. 214) and sets strict requirements for welding, including allowable stresses for static loads and welder competency testing (p. 213-214). Detailed provisions cover rivets and bolts, specifying minimum distances, pitches, and workmanship standards such as heating rivets to a light yellow color (p. 212, 217). Steel joists are regulated, limiting their use in buildings over eight stories unless specific connection standards are met (p. 215-216). These requirements align with structural-steel-design.
Excavations and Foundations
Chapter 28 regulates excavations and footings, requiring protection against soil collapse (p. 219). Allowable soil bearing capacities are defined, such as 5 tons per square foot for solid rock and 2.5 tons for natural sand bed (p. 219-220). These parameters inform structural-load-calculations.
Piles
Section 2803 provides formulas for determining safe loads on wood and concrete piles based on hammer weight and penetration (p. 221). Wood piles must be Dade County pine or approved creosoted wood, with load limits of 20 tons for untreated and 15 tons for creosoted piles (p. 221). Concrete piles must meet specific reinforcement and curing standards, with load tests required when deemed necessary by the building-inspector (p. 221-222). These guidelines support pile-foundation-engineering.
Walls and Partitions
Chapter 29 focuses on solid masonry walls, requiring lateral support at intervals to prevent panel areas from exceeding 256 sq. ft. (p. 223). It mandates reinforced concrete tie-beams and columns for stability, with specific dimensions for vertical rods and ties (p. 223). Table No. 1 specifies minimum wall thicknesses based on building height, increasing from 12 inches at the top stories to 20 inches at the basement level (p. 224).
