TR.20.3 Tapered Member Specification
The following commands are used to specify section properties for tapered I-shapes.
argument-list = f1 f2 f3 f4 f5 (f6 f7)
|f1||Depth of section at start node. Must be greater than f3.|
|f2||Thickness of web.|
|f3||Depth of section at end node.|
|f4||Width of top flange.|
|f5||Thickness of top flange.|
|f6||Width of bottom flange. Defaults to f4 if left out.|
|f7||Thickness of bottom flange. Defaults to f5 left out|
MEMBER PROPERTY 1 TO 5 TAPERED 15.98 0.285 11.98 6.745 .455 6.745 .455
See C:\Users\Public\Public Documents\STAAD.Pro CONNECT Edition\Samples\ US\Doubly_Symm-I_tapered.std for an additional example of designing a member with a tapered I section.
- All dimensions (f1, f2, … f7) should be in current units.
- f1 (Depth of section at start node) should always be greater than f3 (Depth of section at end node). You must provide the member incidences accordingly.
- Shear deformation is not considered for tapered I-Beams and tapered poles. This means that the SET SHEAR command has no effect on the deformation computed for members with these cross sections.
