Q: Which is more economical for a 15-storey building?
A: Hybrid systems typically offer 10-15% savings over pure steel.
Q: How to connect steel beams to RCC columns?
A: Use embedded shear connectors with 150mm development length.
Q: Fire rating for hybrid structures?
A: Spray-applied fireproofing (SFRM) on steel + concrete encasement achieves 2-4 hours.

| Parameter | RCC Structures | Steel Structures |
|---|---|---|
| Material Strength | 25-40 MPa (concrete) | 235-690 MPa (steel) |
| Construction Speed | 0.5-1 floor/week | 2-3 floors/week |
| Span Capability | 10-15m (typical) | 20-50m+ |
| Foundation Load | Heavy (120-150 kN/m²) | Light (60-80 kN/m²) |
| Seismic Performance | Brittle failure risk | Ductile behavior |
| Typical Cost | $150-300/m² | $200-400/m² |
| Design Life | 50-75 years | 50-100 years |
RCC is Better For:
Low-rise buildings (<10 floors)
High mass requirements (blast resistance)
Curved/shell structures
High fire resistance needed (3-4 hrs)
Steel is Better For:
High-rise (>15 floors)
Fast-track projects
Long-span structures
Modular construction
A. Common Hybrid Systems:
Steel Frame + RCC Core (high-rises)
Core handles lateral loads
Steel provides column-free spaces
Steel Beams + Composite Deck
50-60% weight reduction vs RCC
Faster construction
RCC Basement + Steel Superstructure
Combines underground strength with speed above
B. Connection Details:
Embedded Plates: Cast into RCC for steel connections
Shear Studs: 19-25mm diameter @ 300-600mm spacing
Grout Pads: 50-75mm non-shrink grout layers
| Component | RCC Specs | Steel Specs | Interface Requirements |
|---|---|---|---|
| Columns | M30 concrete | H350x350 | Base plate with 4-M30 anchors |
| Floors | 150mm slab | 75mm composite deck | Headed studs @ 450mm c/c |
| Connections | - | End plate moment | 35mm thick embed plates |
| Structure Type | Cost/m² | Time Savings |
|---|---|---|
| Pure RCC | $280 | Baseline |
| Pure Steel | $380 | 35% faster |
| Hybrid | $320 | 25% faster |
Hybrid System: RCC core + steel perimeter
Results:
28% less construction time
15% material cost savings
