4.14.5.13. Hyperbolic Gap MaterialΒΆ
- uniaxialMaterial('HyperbolicGapMaterial', matTag, Kmax, Kur, Rf, Fult, gap)
This command is used to construct a hyperbolic gap material object.
matTag
(int)integer tag identifying material
Kmax
(float)initial stiffness
Kur
(float)unloading/reloading stiffness
Rf
(float)failure ratio
Fult
(float)ultimate (maximum) passive resistance
gap
(float)initial gap
Note
This material is implemented as a compression-only gap material.
Fult
andgap
should be input as negative values.Recomended Values:
Kmax
= 20300 kN/m of abutment widthKcur
=Kmax
Rf
= 0.7Fult
= -326 kN per meter of abutment widthgap
= -2.54 cm
