D1.A.5.7 Design of Web-Tapered Members
AISC 360 05/10 specifications have been incorporated into STAAD.Pro to perform code checking on web tapered wide flange, square, and round shapes.
Note: Member selection cannot be performed on web-tapered members. That is, SELECT ALL, SELECT OPTIMIZE, and PROFILE are not applicable to web-tapered members.
The section properties used for web-tapered members are based on interpolated values between the start and depths of the member. Similar interpolation of values from start and end values is done for square and round tapered members.
