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.
Features
- Snow load on the ground and on the roof (§3.4): zone, shape coefficient μ1 by roof type and pitch, exposure CE and thermal Ct coefficients
- Wind action (§3.3): basic velocity vb, return coefficient cr, kinetic pressure qr, wind pressure p and friction action pf
- Thermal actions (§3.5): climatic zone, extreme temperatures Tmin and Tmax, uniform temperature variation ΔTu by structure type
- Editable return period TR, with coefficient αR for values other than the 50-year reference
- Colour-coded zoning maps with legend for snow, wind and temperature: the province can be picked straight from the map
- Italian municipality database with altitude a.s.l. resolved automatically from offline data, still editable by hand
- Special zoning cases handled automatically (Trieste, Reggio Calabria, the Sardinia divide, minor islands)
- Every formula written out with substituted values and a reference to the relevant code clause
