You can edit the parameters of any beams defined. A dialog box opens containing a number
of input lines dependent on the number of beam materials specified in "Boundary/Beams"
.
The following designations apply:
-
EJ = Bending stiffness of beam
-
GJ = Torsion stiffness of beam
-
E = Young's modulus of beam
-
G = Rigidity modulus of beam = E/2 · (1 +
-
J = Moment of inertia of beam
Due to the fractured tension zone often only a fraction of the theoretical torsional stiffness GJ (often even = 0.0) is adopted for reinforced concrete. If the values are not known, they can be calculated by pressing the "Calculate" buttons.
