Modular Construction Systems

Chassis Cost Simulator

Model a perimeter floor chassis with Australian load combinations, finite‑element beam analysis, and cost estimation. Adjust spans, loads, and section properties to review deflections and material budgets before fabrication.

Geometry & loads

Floor + fixed on joists: 0.00 kPa of 2.00 kPa

Walls: 0.42 kPa
Ceilings: 0.32 kPa
Roof: 0.40 kPa
Fixed joinery: 0.22 kPa

Dead load distribution

Rebalance the default 2.0 kPa between floor finishes, perimeter walls, fixed joinery, ceilings, and roof weight.

Floor finishes 0.64 kPa
External / internal walls 0.42 kPa
Fixed joinery 0.22 kPa
Ceilings 0.32 kPa
Roof structure 0.40 kPa

How it works

Provide chassis dimensions, Australian-standard loads, and pick perimeter / secondary / floor joist profiles. The simulator builds a grillage of perimeter beams, cross struts, and C‑joists in a finite‑element model, applies SLS/ULS combinations, and summarises deflection, shear, bending stress, and material mass. Use the reset button to revert to default assumptions.
