Notes
- 1.
This assumption is taken if a cross sectional area A is specified in the first geometry data field. If \(A=0\) is entered in the first geometry field, Marc uses the beam section data corresponding to the section number given in the second geometry field \((I_x)\). This allows specification of the torsional stiffness factor unequal to \(I_x + I_y\) as well as the shear areas \(A_{\text {s}, x}\) and \(A_{\text {s}, y}\) unequal to the area A or the specification of arbitrary sections using numerical section integration, see [12].

This element uses a one-point integration rule for the stiffness matrix.
