D14.A.2 Member Dimensions
Concrete members that are to be designed by STAAD.Pro must have certain section properties input under the MEMBER PROPERTIES
command.
The following example demonstrates the required input:
UNIT MM
MEMBER PROPERTIES
*RECTANGULAR COLUMN 300mm WIDE X 450mm DEEP
1 3 TO 7 9 PRISM YD 450. ZD 300.
*CIRCULAR COLUMN 300mm diameter
11 13 PR YD 300.
* T-SECTION - FLANGE 1000.X 200.(YD-YB)
* - STEM 250(THICK) X 350.(DEEP)
14 PRISM YD 550. ZD 1000. YB 350. ZB 250.
In the above input, the first set of members are rectangular (450mm depth x 300mm width) and the second set of members, with only depth and no width provided, will be assumed to be circular with 300mm diameter. Note that area (AX) is not provided for these members. If shear area areas (AY & AZ ) are to be considered in analysis, the user may provide them along with YD and ZD. Also note that if moments of inertias are not provided, the program will calculate them from YD and ZD. Finally a T section can be considered by using the third definition above.
