Building Physics & Export Logistics

Fire Resistance & Acoustic Performance: Concrete base provides sound & fire buffer; steel top provides rapid construction speed
Thermal Performance & U-Values: U-values from 0.22 down to 0.11 W/m²K engineered with continuous external insulation and thermal break isolators (GEG / RE2020 / Passivhaus).
Export Delivery & Container Packing: Engineered interface anchor plates and anchor bolt templates shipped prior to main structure
Serviceability Deflection Limits (SLS): Strict deflection limits from L/300 to L/500 preventing cracks in architectural cladding and interior drywalls.

Structural Mechanics, Load Paths & Finite Element Modeling

How vertical gravity, lateral wind, and seismic forces are dissipated through our engineered framing.

1. Vertical Gravity Load Transfer

Hybrid multi-storey structures where upper storeys utilize lightweight steel framing or structural steel columns mounted atop a reinforced concrete ground-floor commercial podium or around a central concrete elevator/stair core. Vertical reactions are transferred via heavy cast-in anchor baseplates and post-installed chemical anchor studs per ETA standards.

2. Lateral Wind & Seismic Ductility

The rigid concrete core or shear podium provides primary lateral shear and torsional resistance (TEd), while the lightweight steel superstructure dissipates seismic energy through ductile diaphragm connections, reducing foundation moment loads by up to 40%.

3. Thermal Break & Moisture Control

Thermal and acoustic decoupling isolator pads at the steel-concrete interface prevent acoustic flanking noise and condensation. Steel framing cavities house mineral wool achieving U = 0.12 W/m²K.
