FAQ

Where do I get the basic wind velocity for Kazakhstan?

Start typing a settlement name — the wind zone and v_b,0 are filled from the SP RK EN 1991-1-4 map. The zone map is also available as a separate page.

Is internal pressure included?

Yes, c_pi per 7.2.9; internal pressure is given as a separate load and is not added to the external pressure.

Can the report be used in a design?

The report shows formulas, substitutions and clause references. Check national parameters against the current National Annex; the designer is responsible for the result.
