Default integration, beam in space
Geometric input data
Radius
Default integration
Beam in a plane: 5 points
Beam in space: 3 points radially, 8 circumferentially (17 total; trapezoidal rule). Integration point 1 is situated at the center of the beam and is used for output purposes only. It makes no contribution to the stiffness of the element; therefore, the integration point volume (IVOL) associated with this point is zero.
Nondefault integration input for a beam section integrated during the analysis
Beam in a plane: A maximum of 9 points are permitted.
Beam in space: Give an odd number of points in the radial direction, then an even number of points in the circumferential direction.
Default stress output points if a beam section integrated during the analysis is used
Beam in a plane: Bottom and top (points 1 and 5 above for default integration).
Beam in space: On the intersection of the surface with the 1- and 2-axes (points 3, 7, 11, and 15 above for default integration).
Temperature and field variable input at specific points for beam sections integrated during the analysis
Give the value at each of the points shown below.

Geometric input data

By allowing you to specify l, the origin of the local cross-section axis can be placed anywhere on the symmetry line (the local 2-axis). In the above figures a negative value of l implies that the origin of the local cross-section axis is below the lower edge of the bottom flange, which may be needed when constraining a beam stiffener to a shell.

For a beam in space the temperature is first interpolated linearly through the flanges based on the temperature at points 1 and 2, and then 4 and 5, respectively. It is then interpolated parabolically through the web.
