Figure D-13 Hinges and Deformed Shape for Final Design
D-5.7
Shear Capacity and Other Capacity Checks.
The initial plastic hinge assumption was that only moment hinges could form
in flexural members and axial-moment interactive hinges could form in columns.
Furthermore, any shear force that reaches the ultimate shear capacity of a member
results in an immediate failure. The final check is to make sure that the shear
capacities were not exceeded in any member.
D-5.8
Alternate Path Method Complete.
Once the model converges and no plastic hinges fail, the building has
satisfied progressive collapse requirements per the UFC.
