Eurocode 2 Shear design of concrete cross-section (rectangular, T-beam, I-beam, box-shaped)

Description:
Calculation of shear reinforcement and verification of concrete strength for general concrete cross-section (rectangular, T-beam, I-beam, box-shaped)
According to:
EN 1992-1-1:2004+AC2:2010 Sections 6.2.1, 6.2.2, 6.2.3
Applicable for:
Rectangular concrete cross-sections and webs of general concrete cross-sections (T-beam, I-beam, box-shaped)
Supported National Annexes:
Nationally Defined Parameters (NDPs) automatically filled for supported countries
All Calculations
Input
MPa
e.g. 30 MPa for concrete class C30/37. For a list of concrete classes see Table of Concrete Design Properties
MPa
cm2
It affects only the strength when no shear reinforcement is required. When in doubt a value of 0 yields conservative results.
MPa
Mean axial stress σcpNEd/Ac in the cross-section due to loading or prestressing (positive when compressive). The influence of imposed deformations may be ignored (see National Annex).
m
The effective depth of the cross-section is measured from the centroid of the tensile reinforcement to the opposite concrete edge in compression along the plane of bending
In the shear analysis of reinforced concrete with small axial force, the approximate value z/d = 0.9 may normally be used, according to EN1992-1-1 §6.2.3(1).
m
For the case where tendon ducts are present within the web a reduced effective web width is applicable as specified in EN1992-1-1 §6.2.3(6)
°
An angle of 90° corresponds to the bars being perpendicular to the plane of the interface. Values less than 90° mean that the bars are in tension due to the shearing action on the interface.
kN
