Hinge Property [SIG]

Hinges represent the points in the structural model where plastic deformation is expected to occur under seismic loads.

Nonlinear

Hinge Stiffness Option [From Section/User Input]: The user can choose whether the hinge stiffness is determined from the assigned section or by user input.

Hinge Section: If the user selects the ‘Hinge Stiffness Option’ as ‘Set to From Section,’ a section should be defined using the ‘Hinge Section’ column.

Hinge Stiffness: If the user selects the option ‘Set to User Input’ in the ‘Hinge Stiffness Option’ column, further definitions can be made using the ‘Hinge Stiffness’ column's ‘Edit…’ option, detailed by Axial Force/Fixity (Ry)/Fixity (Rz).

Linear

Transition along the axes (Tx, Ty, Tz) and rotation (Rx) can be determined for hinges. The definitions can be made either by numbers or by the option ‘Fixed'.

Tx[Fixed/Stiffness]: Transition along X-axis.

Ty[Fixed/Stiffness]: Transition along Y-axis.

Tz[Fixed/Stiffness]: Transition along Z-axis.

Rx[Fixed/Stiffness]: Rotation along X-axis.
