Section ID
Section number (Auto-set to
the last section number +1)
Note
Up to 999999 Section
ID's can be assigned.
Name
Section name (Sect. Name
by default if not specified)
Offset
Display the section Offset currently
set. Location of the Centroid of a section is set as default.

Consider Shear Deformation
Select whether to consider shear
deformation. This option will be applicable for structural analysis,
but will not affect the effective shear areas that appear by clicking
.
Consider Warping Effect
(7th DOF)
Select whether to consider warping
effect. In case of non-uniform torsion which occurs when warping
deformation is constrained, torque is resisted by St.Venant torsional
shear stress & warping torsion. The effects of warping torsion
can be simulated in 1D beam elements for more accurate results
in case of the curved member, eccentric loading, and difference
in centroid and shear center.
When “Consider Warping Effect(7th
DOF)” is considered, warping constant (Iw), warping function (w1,
w2, w3, w4), and shear strain due to twisting moment (γxy1, γxy2,
γxy3, γxy4, γxz1, γxz2, γxz3, γxz4) can be checked in Section
Properties dialog box.

Section Properties
Click to display
the section property data. The section property data table is
either calculated from the main dimensions or obtained from the
DB depending on the method of data entry. [Details]
Note
1
All the above section
property data except for Area and Peri are required for beam elements.
Note
2
The shear deformations
are neglected if the effective shear areas are not specified.
Cyp, Cym, Czp and Czm are used to calculate the bending stresses.
Qyb and Qzb are used to calculate the shear stresses. Peri is
used to calculate the Painting Area.
Note
3
Zyy and Zzz are
used to calculate the strength for pushover analysis when Value
Type Steel Section has been assigned Design > Pushover Analysis
> Define Hinge Properties.
Note
