Structural Concept
Innovation in Foundation Structural Concept
Structural mechanism of foundation reinforcement
-
Flexural resistance mechanism ▶ Determines foundation reinforcement -
Shear resistance mechanism ▶ Determines foundation thickness -
Load path of FRAP using STM
Structural test results of foundation reinforcement
-
Two-way specimen fabrication -
-
Two-way failure testing -
-
Foundation reinforcement improves foundation
performance by 1.6 times. Foundation reinforcement
increases energy absorption capacity
(advantageous for seismic performance).
Applicability
Significant Reduction in Foundation Thickness
This construction method allows a major reduction in foundation thickness by installing foundation reinforcement members that enable strut–tie action within the foundation, efficiently distributing the building loads.
- ㆍReduces foundation thickness by 20~30%
- ㆍReducesconcrete volume
- ㆍLowers construction costs by 10~30%
- ㆍShortens construction duration by reducing excavation and earth-retaining work
- ㆍPrevents ground settlement
| Foundation type | Before change (RC foundation) | Before & after (with foundation reinforcement applied) | Reduction rate (%) | |
| Thickness (mm) | Thickness (mm) | Type | ||
| Parking structure foundation | 800 | 600 | Low-rise | 20 ~30% |
| 900 | 650 | Low-rise | ||
| 1000 | 750 | Low-rise | ||
| High-rise building foundation | 1200 | 900 | High-rise | 20 ~30% |
| 1500 | 1200 | High-rise | ||
| 1800 | 1400 | High-rise | ||
| 2000 | 1500 | High-rise | ||
| 2500 | 2000 | High-rise | ||
| 3000 | 2400 | High-rise | ||

For Apartment Parking Structures
Features
- ·Capable of reducing the thickness of parking structure foundations
- ·Expands the daily concrete-pouring range, reducing construction joints
- ·Significantly shortens excavation time, especially in rock conditions
- ·Able to shorten the overall underground construction period
Maximizing the effect of shortening the construction period by reducing construction joints
For high-rise mat foundations
Features
- ·Possible to reduce the thickness of the mat foundation in the high-rise zone
- ·Reduction of concrete heat of hydration
- ·Reduction in the depth of excavation and earth‑retaining walls
- ·Significant effect on shortening the construction period
- ·Reduction of complaints
- ·Improvement of PQ score through application of new technology
For mat foundations, especially in rock areas, the cost‑reduction effect and the shortening of the construction period are maximized
