Section Properties - DB/User


  • Enter the sectional properties for the following structural elements: Truss, Tension-only, Compression-only, Cable, Gap, Hook, and Beam Element.
  •  The section data can be entered by the following 2 methods in the dialog box:
    1. Select a section from the DB (database) of the standard sections for a country.
    2. Enter the main dimensions of a standardized section shape.



From the main menu, select [Properties] tab> [Section Properties] group > [Section Properties] > [DB/User]

Section Shape List

Select a section shape (Angle, Channel, H-Section, T-Section, Box, Pipe, Double Angle, Double Channel, Solid Rectangle, Solid Round, Octagon, Solid Octagon, R-Octagon, Track, Solid Track, Half Track, Cold Formed Channel & U-Rib).

User : Enter the main dimensions of a standardized section shape.

H, B1, ... : Refer to the dimension information diagram in the dialog box.

NOTE.png When the user inputs r1 and r2, the calculation of Ixx does not take into account r1 and r2.

DB : Select a section from the DB of the standard sections for a country.

Section Name

Enter directly a DB section name or select a desired DB from the Section list. When the section name is directly entered, it must correspond to the format of the DB section names.

Ex) KS, JIS : H 400X200X8/13, AISC : W36X280, CISC : HP310x110, BS : UB 406x178x54, DIN : HD400x288

NOTE.png When specifying Double Angle or Double Channel sections, assign the sectional shape in the list and select User. Then, select DB and Sect. Name from Get Data from Single Angle (or Channel) or directly enter the main dimensions of the section.

Consider Warping Effect (7th DOF)

You have the option to consider the torsional effects. When there is an uneven torsion resulting from the restricted torsional displacement, torque is resisted by St. Venant's torsional shear stress and warping torsion. In cases involving curved members, eccentric loads, or differences between the center of gravity and the shear center, simulating the warping torsion effect using a 1D beam element can provide more accurate results.

When considering the warping effect (7 degrees of freedom), the warping coefficient (Iw), warping functions (w1, w2, w3, w4), and shear deformations due to the twisting moment can be checked in the sectional properties dialog box.
