Input Transvers Stiffner Definition

Table tbTransverseStiffnerDef

PURPOSE

Add transverse stiffeners to a stringer.

The shear capacity at member ends is very dependant on how the program interprets the end condition. AASHTO 10.48.8.3 specifies that a member’s end will have a reduced shear capacity if it is a “simply supported end ( Shear Theory SS-5.2.3). The program looks at each member end and if (1) the member end has no other attached members of any kind, and (2) the member end node is not constrained in rotation, then it is a simply supported end.
