Verification of rectangular cross-section made from plain concrete
Verification of rectangular cross-section made from plain concrete
The cross-section is rectangular, loaded by the bending moment MEd, normal force NEd (applied in the cross-section centroid) and by the shear force VEd.The shear strength is provided by (Art. 12.6.3):
where: Acc - compressed area of concrete
Standard value of the coefficientk is built-in the program (Art. 12.6.3) – this value can also be adjusted in the program based on the selected National annex.
Strength of concrete cross-section subject to the combination of bending moment and normal force is derived from the following expressions (Art. 12.6.1) depending on the normal force eccentricity e:
As the greater of:
Formula express the strength with linear stress-strain diagram of cross-section without the crack.
Minimal values of excentricity are from article 6.1(3).
Standard values of coefficientsαcc,pl, αct,pl, γc are built-in the program – these values can also be inputted by the user depending on the selected National annex.
