This command is used to construct an elastic perfectly-plastic gap uniaxial material object.
| uniaxialMaterial ElasticPPGap $matTag $E $Fy $gap <$eta> <damage> |
| $matTag | integer tag identifying material |
| $E | tangent |
| $Fy | stress or force at which material reaches plastic state |
| $gap | initial gap (strain or deformation) |
| $eta | hardening ratio (=Eh/E), which can be negative |
| $damage | an optional string to specify whether to accumulate damage or not in the material. With the default string, "noDamage" the gap material will re-center on load reversal. If the string "damage" is provided this recentering will not occur and gap will grow. |
