Steel Column Design per. EUROCODE 2 Calculator and Equations

Steel Column Design Calculator and Equations per. EUROCODE 2

EN 1992 Eurocode 2 applies to the design of buildings and other civil engineering works in plain, reinforced and prestressed concrete. It complies with the principles and requirements for the safety and serviceability of structures, the basis of their design and verification that are given in EN 1990: Basis of structural design. EN Eurocode 2 is concerned with the requirements for resistance, serviceability, durability and fire resistance of concrete structures.

Precision:

Input - Insert the axial load, material property, safety factor, effective length coefficient (by selecting the connection type) and lenght of the steel column.
