Concrete Cross Section with Steel Profile Verification

Verification of the concrete cross-section reinforced by steel section is carried out for two load cases:

1. for the maximum value of bending moment and the corresponding shear force (M_max + Q)
2. for the maximum shear force and the corresponding bending moment (Q_max + M)

In both cases, the load enters to the assessment with an influence of normal force, which is defined separately. Its value is identical for both of load cases. Internal forces are, prior to analysis, pre-multiplied by the reduction coefficient of bearing capacity. This coefficient represents the degree of uncertainty of the determination of theoretical values of internal forces and as thus introduces into the analysis with such values certain reliability. The value of this coefficient is determined solely by the user.

Verification of cross-section

Internal forces provide by the "Sheeting Check" program are considered per 1 m run of the structure width. Therefore, the units of shear force Q are kN/m and of bending moments M are kNm/m. For dimensioning of individual sections these forces are, prior to verification analysis, automatically multiplied by their spacing a [m] to get their values at the cross-section center of gravity, i.e. shear force Q in kN and bending moment M in kNm.

The program exploits following types of analyses for check of concrete cross-sections reinforced by steel profile:

• Verification according to EN 1994-1-1 (EC 4)
• Verification according to AISC 360-22 (LRFD, ASD)
