Required Reinforcement Total

The table shows the maximum reinforcement areas of all analyzed surfaces, which are determined from the internal forces of the load cases, load and result combinations selected for the ultimate limit state design.

Figure 5.2 Window 2.1 Required Reinforcement Total
Surface No.

This column shows the numbers of the surfaces where the governing points are located.

Point No.

In these FE nodes or grid points , the greatest required reinforcement was determined for each position and direction. The reinforcement type is displayed in the Symbol column E.

The FE mesh nodes M are generated automatically. In contrast to this, the grid points G can be controlled in RFEM, as user-defined result grids are possible for surfaces. The function is described in chapter 8.13 of the RFEM manual.

Point-Coordinates X/Y/Z

The three columns show the coordinates of the respective governing FE nodes or grid points.

Symbol

Column E displays the type of the reinforcement. For the four (or six) longitudinal reinforcements, it shows the direction (#1{1#1}, #2{1}4# and #3{2{6#, if available) as well as the surface side (#4{top#4} and #5{bottom#5}).

The reinforcement directions are defined in the Reinforcement Layout tab of the 1.4 Reinforcement window (see chapter 3.4.2).

Top and bottom position

The top reinforcement is defined on the surface side in direction of the negative local surface axis z (-z). Accordingly, the bottom reinforcement is defined in direction of the positive z-axis (+z). The Figure 3.28 shows axis systems of the surfaces.

The shear reinforcement is indicated by asw.

Required Reinforcement

This column displays the reinforcement areas that are required for the ultimate limit state design .

Basic Reinforcement

This column shows the user-defined basic reinforcement specified in the Longitudinal Reinforcement tab of the 1.4 Reinforcement window (see chapter 3.4.3).

Additional Reinforcement

If you perform the ultimate limit state design exclusively, the column Required displays the difference between required reinforcement (column F) and provided basic reinforcement (column G).

When the serviceability limit state designs were additionally performed, you can see here the reinforcement areas that are required by the specifications in the Longitudinal Reinforcement tab of the 1.4 Reinforcement window (see chapter 3.4.3) to satisfy the serviceability limit state designs. The Provided column shows the reinforcement that is available as additional reinforcement for the serviceability limit state design according to the specification in the Longitudinal Reinforcement tab of the 1.4 Reinforcement window.

Note

The final column indicates non-designable situations or notes referring to design issues. The numbers are explained in the status bar.

The button shown on the left allows you to view all [Messages] of the current design case. A dialog box with a message overview appears.
