{live-template:Tutorial} To model nonlinear frame behavior, frame hinges must be used. The nonlinear material behavior is only used to develop the moment rotation or other response curves for the hinges. h1. |
...
Key Steps to Setup a Model With Hinges |
...
* Define hinge properties using "Define > Section Properties > Hinge Properties" menu command. |
...
* Assign the hinges to the frame elements in the model by using Assign > Frame > Hinges menu command. |
...
* Create a nonlinear load case and run the analysis. |
...
* Use "Display > Show Hinge Results" menu command to plot the deformation of the hinges vs. the applied loads, such as plastic rotation of the hinge vs. moment. h1. |
