I need maximum force in every drift in one Composite Shear Wall(CSPSW). I utilized dynamic Explicit and apply cyclic loading . I obtained hysteresis curve of my analysis. But how can I procure backbone curve out of analysis outputs?
Dear Moein,
First of all note that you need to work on the envelope of the hysteresis curves.
Moreover, you require many more than one analyzed case. In fact, backbone curves are generalized force-displacement curves portraying the whole behavior of system from loading initiation until collapse, and should include the material as well as geometrical parameters as variables.
You can use either of numerical (soft computing) or calibrated analytical approaches.
For further information, you can call me whenever you wish.
