AMetric Toolbox
A single application bundling calculation and verification tools for structural engineering, designed for everyday work in professional studios and engineering firms. Four tools are free forever.
Each tool is self-contained but shares the same interface and the same usage logic.
A single installer brings every tool to your computer: four of them stay free forever, while the paid modules can be tried for 30 days with no feature limitations.
The suite is developing rapidly. If a feature you need is missing, write to me: I'll do my best to include it in the next release.
Available Free Variable loads NTC 2018
Snow, wind and thermal actions to NTC 2018Three tabs — snow, temperature and wind — all driven by a single input: the location. Once the municipality is picked, the app derives province and altitude, finds the code zone on the map and develops the calculation step by step, showing every NTC 2018 formula with the values already substituted, ready to be copied into the design report.

Available Free AMetric_sez_CA
Reinforced-concrete section analysis & checksAMetric_sez_CA verifies rectangular reinforced-concrete sections to Italian NTC 2018 and the 2019 Circular: ultimate limit state (ULS) resistance, shear checks and serviceability (SLS) checks on stresses and crack width. Geometry, reinforcement and internal forces are defined in a few steps, and every check comes with its domain plot, with the N-M action points overlaid on the resistance boundary.

Available Free Seismic spectra NTC 2018
Elastic and design response spectraDefines the seismic action of a site to Italian NTC 2018, from basic hazard to the design spectrum. Once the point is placed on the map, the app interpolates the ag, F0 and Tc* parameters from the four surrounding nodes of the reference grid and builds the spectra for every limit state; each plot carries a draggable point that reads the period T and returns the corresponding acceleration and displacement.

Available Seismic Isolator HDRB
Design, optimization and verification of circular HDRB seismic isolatorsSoftware for the design and verification of circular HDRB (High Damping Rubber Bearing) seismic isolators to EN 15129, EN 1337-3 and NTC 2018. The built-in optimizer automatically searches for the smallest-diameter isolator geometry that satisfies every check, while still delivering the stiffness and damping the designer requires. Checks are summarized with bar charts and reported in a detailed calculation report with formulas, results and comparison against the code limits. The isolator's technical drawing updates in real time as parameters change, while the F-Δ hysteretic diagram shows the force-displacement loop and the energy dissipated per cycle.

Available Free Activity Coordination
Shared schedule for the practice's activitiesA Gantt chart for the practice's work, built for people working alone or in a small team. Tasks belong to a project, are assigned to a person, and are dragged to change dates and progress. The data lives in a folder you choose — on your NAS, Google Drive or OneDrive — and never passes through an AMetric server: there is no account to create and no subscription to renew.
