Property dialog

Used to assign prismatic cross sections to members.

Opens when the Beam Profiles > Prismatic Profiles tool is selected in the Specifications group on the Specification ribbon tab.

Note: The Properties - Whole Structure dialog also opens simultaneously so that some of the other options available from that dialog may be utilized.

Circle tab

SettingDescription
YD Section diameter.
Material Check this box and select the material from the drop down list if the new member property tag should include the material constants.

Rectangle tab

SettingDescription
YD Depth of the member in local y direction.
ZD Width of the member in the local z direction.

Tee tab

SettingDescription
YD Depth of the member in local y direction.
ZD Width of the flange.
YB Depth of the stem (web).
ZB Width of the stem (web).

Trapezoidal tab

SettingDescription
YD Depth of the member in local y direction.
ZD Top width.
ZB Bottom width.

General tab

SettingDescription
AX Cross sectional area of the member.
AY Effective shear area in local y-axis.
AZ Effective shear area in local z-axis.
IX Torsional constant.
IY Moment of inertia about local y-axis.
IZ Moment of inertia about local z-axis (usually major).
YD Depth of the member in local y direction. Used as the diameter of section for circular members.
ZD Depth of the member in local z direction. If ZD is not provided and YD is provided, the section will be assumed to be circular.
YB Depth of stem for T-section.
ZB Width of stem for Tee section or bottom width for trapezoidal section.

Tapered I tab

SettingDescription
F1 Depth of section at start node.
F2 Thickness of web.
F3 Depth of section at end node.
Note: F3 should be less than F1 (i.e., the section should decrease in depth from start to end). You must provide the member incidences accordingly.
F4 Width of top flange.
F5 Thickness of top flange.
F6 Width of bottom flange. Defaults to F4 is zero.
F7 Thickness of bottom flange. Defaults to F5 if zero.

Tapered Tube tab

SettingDescription
Type of Section Select one of the profile shapes:
  • Round
  • Hexdecagonal – 16-sided
  • Dodecagonal – 12-sided
  • Octagonal – 8-sided
  • Hexagonal – 6-sided
  • Square – 4-sided
d1 Depth of section at start of member.
d2 Depth of section at end of member.
th Thickness of section (constant throughout the member length).
Notes:
  1. 断面特性は、薄肉断面に適用可能な公式を使用して計算されます。
  2. せん断変形は、テーパー付きI形はりおよびテーパー付きポールでは考慮されません。つまり、SET SHEARコマンドは、これらの断面を持つメンバーについての変形の計算には影響しません。

Assign Profile tab

Used to instruct the program to select a suitable steel section based on a profile classification, such as beam, column, double-angle, etc.

SettingDescription
Select Profile Specification Specify a profile by selecting one of the options:
  • Angle
  • Double Angle
  • Beam
  • Column
  • Channel
The program will then assign a section based on that profile from the relevant built-in Steel table.
