Core Structural Detailing
Residential Building Structural Design
- RCC concrete grade used is M-20 for structural strength
- Reinforcement steel grade is Fe-500 or higher
- Structure is designed for G+4 floors
- All designs follow IS 456:2000 and IS 800:2007 standards
- Proper water-cement ratio must be maintained on site
- Minimum clear cover is defined for footing, column, beam, and slab
- Lap length of reinforcement bars should be 50D
- Column sizes vary based on load (C1, C2, C3, C4 types)
- Footing types include isolated and combined footings
- Foundation depth depends on soil condition
- PCC layer (1:4:8) is provided below footing
- Plinth beam ensures structural stability at ground level
- Beam sizes and reinforcement vary as per load requirements
- Slab thickness is approximately 5 inches
- One-way and two-way slabs are used in design
- Staircase is RCC waist slab type with standard riser and tread
- Lintel beams are provided above doors and windows
- Lift pit includes RCC shear wall with proper depth
- Curing time is essential for strength (7–14 days depending on work)
- Formwork removal timing must follow safety standards
Foundation Detail
Foundation Detail for Contraction
- Footing type (isolated, raft, pile)
- Reinforcement (rebar size, spacing)
- PCC (plain cement concrete) layer
- Soil level + compaction notes
- Column starter bars
Key Details:
- Vertical grooves or weakened planes are introduced.
- Spacing typically:
- Slabs on grade: 3–5 m apart
- Footings/walls: 6–12 m apart (depends on design)
- Depth of joint: about ¼ of slab thickness
- Filled with flexible sealant if exposed
Column & Beam Detailing
RCC Structural Basics
- Longitudinal bars (main steel)
- Minimum: 4 bars (rectangular), 6 bars (circular)
- Diameter: usually 12 mm – 32 mm
- Lateral ties (stirrups)
- Hold main bars in position
- Prevent buckling
- Minimum cover:
- 40 mm (or as per design/exposure)
- Tie spacing:
- Generally 150–300 mm
- Near beam-column joints → reduce spacing (100 mm typical)
- Lap length:
- About 40–60 × bar diameter
- Avoid lapping all bars at same level
- Hook angle:
- Ties with 135° hooks for seismic safety
Column & Beam Detailing
Standard Layers (Top → Bottom)
- Finish layer
- Tiles / china mosaic / stone
- Protects waterproofing
- Waterproofing layer
- Membrane / chemical coating / brick bat coba
- Slope screed (1:40 to 1:60)
- Ensures water drainage
- RCC slab (main structure)
- Thickness: 100–150 mm (typical)
- Ceiling plaster (bottom)
- Smooth internal finish
Architectural wall section detail
Architectural
Foundation & Base
- Footing (concrete base)
- Damp-proof course (DPC)
- Plinth beam
- Ground level vs floor level
2. Wall Assembly
- Structural layer (brick, concrete, block, or frame)
- Insulation (thermal/acoustic)
- Vapor barrier
- Internal finish (plaster, drywall)
- External finish (cladding, paint, stone, etc.)
3. Floor Connection
- Floor slab (RCC, timber, etc.)
- Floor finish (tiles, wood, etc.)
- Skirting detail
4. Openings (if section cuts through window/door)
- Lintel (load-bearing support above opening)
- Frame fixing detail
- Sill level and treatment
5. Roof Connection
- Roof slab or truss
- Waterproofing layer
- Parapet wall (if flat roof)
- Drainage slope and outlet
From outside → inside:
- Exterior cladding / paint
- Cement plaster
- Brick/block wall (230mm typical in India)
- Insulation layer (optional)
- Internal plaster (12–15 mm)
- Paint finish
