Answer: Both hinges and links may be used to model localized nonlinear behavior. Depending on modeling goals, either one may be most appropriate. A summary of the primary advantages and comparisons are as follows:
Hinges
...
- Hinges are suitable for pushover analysis since hinge state may be displayed graphically for each pushover increment.
...
- Multiple hinges may be assigned along element length to simulate the distribution of plasticity along the member.Hinges may be used to model strength loss, while link response should increase monotonically.
Links
...
- More modeling features are available for links, including energy-dissipation capability, a variety of hysteresis models, and such advanced seismic properties as isolation and Wen plasticity.
...
- Various link properties are available for modeling steel, concrete, and several types of bearing behavior.
