3Muri at a glance

The leading software for nonlinear structural analysis of masonry structures.

3Muri — Full 3D model — church with structural roof

3Muri — full 3D model of a church with structural roof
FME method Frame by Macro-Element
Innovative FME computation method An innovative computation method (FME — Frame by Macro-Element) captures the structure's real behaviour under seismic actions, rather than a simplified approximation.
Macro-element modeling Macro-element modeling of existing masonry structures represents real wall behaviour faithfully, without resorting to oversimplified or overly generic assumptions.
Wide range of functionalities A wide range of functionalities and additional modules lets you extend the software exactly as far as each project needs, from basic checks to advanced, specialised analysis.
Reinforcement of masonry structures Strengthen existing masonry using steel or FRP frames, or reinforced masonry techniques, all designed and verified directly on the model.
Purpose-built pushover analysis Not a generic FEM tool adapted for masonry — 3Muri was designed from the ground up for nonlinear pushover and static analysis of new and existing masonry buildings, under EC6, EC8, NTC and SIA.
Simple input, full 3D model Draw the structure graphically with intuitive commands and 3Muri builds the complete 3D calculation model — walls, floors, roofs and reinforcement — automatically behind the scenes.

Modelling.

Model the building exactly as it is — no shortcuts, no oversimplified assumptions, just a structural model you can trust.

Draw it as it really is Model masonry panels, RC, steel and timber beams and columns, tie rods and bond beams as real structural objects — checking both data and results interactively as you build.
Import DXF and IFC in minutes Bring in existing geometry straight from DXF and IFC files, then assign material properties from built-in standard tables — nothing gets redrawn from scratch.
Floors and roofs, exactly as built Model floors with their real, physical stiffness instead of assuming they're rigid, and shape structural or non-structural roofs — down to irregular, non-planar pitches over existing walls.
Composite elements in one step Combine a panel with a tie beam, a beam, a tie rod or reinforcement inside a single object, while loads on floors and walls distribute automatically according to how the building actually carries them.

Analysis.

An engine built to tell you the truth about how masonry behaves in an earthquake — not just whether it passes on paper.

See the real seismic behaviour The FME (Frame by Macro-Element) method schematizes the building as an equivalent frame of macro-elements, pinpointing exactly where it's weak and exactly what intervention fixes it.
Loads that follow reality Self-weight is calculated automatically, and permanent and variable floor loads are routed to the walls that actually carry them, based on real flexible or rigid diaphragm behaviour.
One model, every material Analyse masonry side by side with reinforced concrete, steel and timber in a single 3D model — for a brand-new design or the seismic assessment of an existing building.
Compliant wherever you build Checks run automatically against EC6, EC8, NTC, SIA and other national codes, applying the correct national annex as soon as you set the project's location.

Retrofit & Reporting.

From diagnosis to strengthening design to a finished calculation report — without ever leaving the model.

The report writes itself The built-in post-processor turns results straight into a complete, ready-to-submit calculation report — no manual assembly of graphs, checks and tables.
A full toolkit for strengthening Simulate tie rods, FRP/FRCM strengthening, reinforced plaster, wall injections, floor stiffening, and reinforced concrete or steel encirclements — directly on the existing model.
A seamless handoff to AxisVM and SaiTu New reinforced concrete or steel elements added during a retrofit are designed automatically in connection with AxisVM, with further checks available through SaiTu.
Catch what the global model misses Go beyond the overall model with the Local Mechanisms module and Local Verification Suite, checking out-of-plane collapse mechanisms and local safety in detail.

3Muri is a structural analysis software purpose-built for the seismic and static design of masonry and mixed structures. It covers both new buildings and the assessment and strengthening of existing masonry, using the validated FME (Frame by Macro-Element) calculation method, with full compliance to Eurocode 6 and Eurocode 8. 3Muri is widely regarded as the No. 1 nonlinear analysis software for existing masonry buildings.

3Muri isn't a generic FEM package adapted for masonry — it was engineered from the ground up to capture how masonry actually behaves under seismic action, giving a far more faithful picture than simplified approximations. The FME method has been validated at numerous national and international universities and research centres, not just in-house.

3Muri is also one of the leading masonry structural analysis solutions internationally, with a long track record of completed projects and years of real-world engineering experience behind it — and to date, there is no proper alternative that matches what 3Muri offers for masonry structures.

3Muri is offered in several packages — START, PRO and EXPERT — each including a full, unrestricted, perpetual license of 3Muri Professional, with additional modules available on top such as Local Verifications, Multi-threading, FEA and Time-History analysis. Because the right combination depends on your workflow, there's no single number that covers every user.
