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

Vertical gravity loads from upper storeys and roof trusses are distributed uniformly along cold-formed C-studs spaced at 400mm or 600mm centers. High-tensile S350GD galvanized steel delivers extraordinary axial compressive strength (Nb,Rd), resisting localized web crippling and flexural-torsional buckling via intermediate track bracings.

2. Lateral Wind & Seismic Ductility

In-plane lateral shear loads caused by high-velocity gale winds and seismic ground accelerations are resisted through engineered X-strap tension bracing or structural OSB/fiber cement diaphragm sheathing. Engineered hold-down brackets anchored into the foundation slab resist overturning moments without anchor bolt pullout.

3. Thermal Break & Moisture Control

External continuous insulation (ETICS/EIFS) paired with high-density mineral wool insulation between studs achieves U-values down to 0.13 W/m²K. Thermal break isolating tapes prevent thermal bridging through steel flanges, completely eliminating cold spots and condensation per EN ISO 13788.
