GGU-RETAIN: "Struts" menu item

Struts are defined in this dialog box.

It is necessary to enter the following information:

• Depth [m] = position of the strut head

• Inclination [°] of the strut

• Length [m] of the strut

• EA [kN/m] = axial stiffness of the strut

• EI [kN·m²/m] = bending stiffness of the strut

• V Load [kN/m²/m] = vertical load on the strut

• Hinge (right)
  Here you specify whether the strut is hinged or rigidly fixed to the wall.

• Hinge (left)
  Here you specify the support conditions of the strut on the "opposite side".

If neither hinge option is selected, the following happens:
The strut is then modelled with only half length!! On the left-hand edge of the "half" strut complete fixation is assumed. The support can be vertically displaced.

• If you have defined a vertical load on the strut, you will also get its distribution of moments. Of course, this only works if the strut is divided into several rods (finite elements, see “Theoretical principles: Structural system”). The maximum number of rods that can be specified is 20.
