## What is ECCS EC3 1.4?

ECCS EC3 1.4 Calculator provides a database of stainless steel products and suppliers and also calculates the resistance of beams and beam-columns (subject to major axis bending) according to EC3-1-1 and EC3-1-4. 

The following verifications are considered:
-	Corrosion resistance class;
-	Classification of the cross section;
-	Calculation of effective properties (reduction factor);
-	Calculation of axial cross-sections resistance: cross-section; flexural buckling; torsional buckling and torsional-flexural buckling;
-	Calculation of bending resistance: cross section and lateral torsional buckling;
-	Bending and compression resistance
-	Shear resistance;
-	Fire design.
