More than a method,
a tangible advantage
The stress field method is justified not only by its theoretical rigour — it delivers tangible economic, environmental and structural gains for every project.
Lower construction costs
By precisely modelling the stress flow, ConcrIT avoids the excess thicknesses and superfluous reinforcement imposed by prescriptive approaches. Less steel means direct savings on material, rebar labour and construction schedule.
Invest in thinking rather than in material. The accuracy of the model replaces empirical margins. The engineer regains control of the force flow — and the design office offers its client an economical and justified design. Less material also means less concrete and steel put in place — and therefore a reduced environmental cost (see below).
Verification of complex structures
ConcrIT lets you model any geometry — deep beams, nodes, corbels, discontinuity regions, non-prismatic sections — with the same ease as a standard member, and obtain clear, accurate results. Where classical code-based methods impose simplified models valid only for standard cases, ConcrIT relies on generalized stress fields to handle the real geometry of the structure directly.
Nodes, corbels, openings, changes of section — regions where the Bernoulli (plane sections) assumption does not apply.
Shear verification in slabs, deep beams and walls — including in regions where it combines with bending, exactly where simplified code formulas are least reliable.
A member subjected simultaneously to several actions (axial force, bending, shear, torsion) is checked within a single consistent model — instead of adding up separate checks via approximate interaction formulas.
Before/after state for modifications to existing structures
This same modelling freedom makes it easy to compare a structure’s initial state with its projected state after modification. ConcrIT models the existing (as-built) geometry and reinforcement, then the modified configuration, to directly visualize the stress redistribution and design strictly the strengthening needed — without demolishing or over-designing as a precaution.
A frequent case in technical renovation: cutting an opening (door) in a shear wall, or core drilling a wall or transfer beam to route ducts. ConcrIT compares the before/after state to check the stress redistribution around the opening and design the necessary local strengthening.
Evaluation of the residual capacity from existing drawings and in-situ measurements, then design of the added reinforcement, jacketing or shotcrete required to reach the target state.
Validation of an increased imposed load (e.g. storage → offices → housing) with rigorous justification, instead of systematically replacing the members.
The best structure is often the one you don’t need to rebuild. By proving that the existing structure can absorb the new loads or accommodate an opening, ConcrIT avoids heavy works — and the concrete and steel that would have been needed to carry them out.
Reducing the carbon footprint of structures
Concrete is the most consumed construction material in the world — and among the most energy-intensive. Its production accounts for about 8% of global CO₂ emissions. At the same time, sand — an essential aggregate — is becoming a resource under pressure worldwide. Optimizing a structure directly reduces its material mass and therefore its impact.
Cement clinker production is highly carbon-intensive (≈ 0.8 kg CO₂/kg). Quality sand for concrete is extracted faster than it renews. Reducing concrete volumes is an environmental and economic necessity in the medium term.
Each tonne of reinforcing steel represents ≈ 1.8 t CO₂. Reducing reinforcement ratios by 15% on a standard building typically corresponds to dozens of tonnes of avoided emissions.
ConcrIT turns structural rigour into an environmental lever. Less concrete, less steel, with no compromise on safety — thanks to modelling that truly exploits the structure’s capacity instead of ignoring it.
