Bridge MULTICOM Girder Overview and Features
Complete Composite
Action of
Concrete Panel and I-Girder Achieved!
By combining concrete panels with I-girders, issues such as cracks and height differences due to thermal expansion and contraction of the steel during temperature changes before and during the non-shrink concrete pour are completely resolved. This eliminates quality issues caused by differential deflection between the panel and the girder.
Problems with Conventional Methods
When the I-girder is manufactured with greater camber than the concrete panel
The girder’s mid-span height becomes greater than at both ends.
Excellent Constructability,
Outstanding Cost-Effectiveness,
Revolutionary Structural Performance
- Eliminates all high-altitude work, ensuring superior safety
- Simplified full construction process enables easy installation
- Low neutral axis prevents overturning during erection
- Reduces steel usage by 30–50% compared to conventional steel composite girders
- Minimizes land lease area for manufacturing yards
- Short construction cycle reduces overall cost
- Enables concrete crack control by compensating for stress loss during manufacturing stages
- No cracks occur thanks to full prestressing method
- Achieves full composite action between precast panel and steel using T/B connection device
Maintenance Cost Reduction via Re-Prestressing
Efficient maintenance using unbonded PC strands
[ Re-tensioning possible during service life, excellent durability and appearance ]
