If you dimension reinforced concrete bars with 1•2•Build, 1•2•Build will determine the optimal width and/or height of the concrete cross-section – if requested, of course. You can also choose a specified width and height at any time during the dimensioning process. Whichever strategy you choose, 1•2•Build will always calculate the required reinforcement sections for you and, of course, allow you to report those calculated sections:
shows the calculated sections for the bottom and top reinforcement; reinforcement sections are always drawn on the side of the section where they are to be applied;
shows the results of the reinforcement parallel to the weak axis (the web reinforcement);
shows the calculated sections for the transverse reinforcement; this transverse reinforcement provides resistance to the transverse force Vz. More specifically, this concerns the section of the vertical legs of the stirrups per unit length of the beam.
When one of the above reinforcement results is displayed in the model window, you can double-click on a bar. A dialogue box will appear in which you can calculate or manually change the buckling length. However, keep in mind that 1•2•Build automatically calculates the buckling lengths of all bars in a safe manner during the dimensioning process. If you manually adjust the buckling lengths for heavily compressed bars, keep in mind that a smaller buckling length may result in smaller reinforcement sections. We therefore recommend that you always leave the buckling lengths equal to the values calculated by 1•2•Build itself.
