Reinforced concrete design suite

Two explicit simplified EN 1992-1-1 beam flexure and concrete-shear models plus a clearly limited linear N–M column-section screening check.

Reinforced concrete design suite

Three explicit calculation modules: simplified beam flexure, concrete shear resistance and preliminary linear N–M interaction for a column section.

EN 1992-1-1 (EN 1992-1-1:2004+A1:2014; explicit simplified subset)

Rectangular singly reinforced beam with assumed yielded tension steel and a fixed rectangular compression block. Equation: f_cd = alpha_cc*f_ck/gamma_C; f_yd = f_yk/gamma_S; x = A_s*f_yd/(0.8*f_cd*b); z = d-0.4*x; M_Rd = A_s*f_yd*z

The tool supports preliminary analysis. The user selects γC, γS, αcc, CRd,c and the x/d and slenderness limits from the applicable project documentation; no National Annex is selected automatically. It does not perform a complete EN 1992-1-1 verification, automatic minimum or maximum reinforcement checks, full SLS, stirrup design, column stability or second-order analysis. The column module excludes tension, biaxial bending and nonlinear section interaction.
