Concrete Spans 2 Lecture 24

Reinforced Concrete Design

  • economical & common
  • resist lateral loads

Concrete Spans 4 Lecture 24 Elements of Architectural Structures

Reinforced Concrete Design

  • beam supported
    • slab depth ~ L/
    • 8”–60” deep
  • one-way joists
    • 3”–5” slab
    • 8”–20” stems
    • 5”-7” webs

The Architect’s Studio Companion

Concrete Spans 5 Lecture 24

Reinforced Concrete Design

  • two-way joist
    • “waffle slab”
    • 3”-5” slab
    • 8”-24” stems
    • 6”-8” webs
  • beam supported slab
    • 5”-10” slabs
    • taller story heights

Concrete Spans 7 Lecture 24

Reinforced Concrete Design

  • one-way slabs (wide beam design)
    • approximate analysis for moment & shear coefficients
    • two or more spans
    • ~ same lengths
    • wu from combos
    • uniform loads with L/D3
    •  (^) n is clear span (+M) or average of adjacent clear spans (-M)

Concrete Spans 10 Lecture 24 Elements of Architectural Structures

Shear in Concrete

  • critical section at d/2 from
    • column face, column capital or drop panel

Concrete Spans 11 Lecture 24

Shear in Concrete

  • at columns with waffle slabs

Concrete Spans 13 Lecture 24

General Beam Design

  • f’c & fy needed
  • usually size just b & h
    • even inches typical (forms)
    • similar joist to beam depth
    • b:h of 1:1.5-1:2.
    • bw & bf for T
    • to fit reinforcement + stirrups
  • slab design, t
    • deflection control & shear^6

Concrete Spans 14 Lecture 24

General Beam Design (cont’d)

  • custom design:
    • longitudinal steel
    • shear reinforcement
    • detailing
