Reinforced Concrete Beam Design per. Eurocode 2

Reinforced Concrete Beam Design 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.

EN 1992-1-1	Eurocode 2: Design of concrete structures - Part 1-1: General rules and rules for buildings
EN 1992-1-2	Eurocode 2: Design of concrete structures - Part 1-2: General rules - Structural fire design
EN 1992-2	Eurocode 2: Design of concrete structures - Part 2: Concrete bridges - Design and detailing rules
EN 1992-3	Eurocode 2: Design of concrete structures - Part 3: Liquid retaining and containment structures

Precision:

Input - Insert the dimension of the beam cross-section and span length, loads with their respective safety factors and material properties of the concrete and the reinforcement steel.
