Hysteretic shear model under axial force variation
Parameters required for the above ZeusNL curve type is described as below from left
column to right column.
1. The first column represents the level of axial force of interest (zero axial force level,
three levels of compressive axial force and two levels of tensile axial force) which
can be defined by user. Say for instance, if you choose 10%, 20%, and 30% of axial
capacity in compression, and 10% and 30% of axial capacity in tension, you can
define parameters in the first column as 0.0 0.1, 0.2, 0.3, 0.1 and 0.3 from top to
bottom. Hence, level of axial force of interest can freely be defined by user.
2. The first row of the second column is an identifier of each hysteretic curve. The
‘curve number’ stands for a numbering in sequence in order to trace each hysteretic
curve assigned to each direction of a member. For example, if a bridge structure
has three piers, user has to define six curves (three in longitudinal and three in
transverse direction). In this case, user can define the ‘curve number’ as 1 to 6
corresponding to each direction of each pier. The second and the third row of the
second column represent the axial force capacity in compression and in tension,
respectively (these values should be positive)
3. The third column represents shear displacement at cracking corresponding to each
level of axial force defined in the first column.
4. The fourth column represents shear displacement at yielding corresponding to each
level of axial force defined in the first column.
5. The fifth column represents shear displacement at ultimate corresponding to each
level of axial force defined in the first column.
6. The sixth column represents shear force at crack corresponding to each level of
axial force defined in the first column.
7. The seventh column represents shear force at yielding corresponding to each level
of axial force defined in the first column.
8. The eighth column represents shear force at ultimate corresponding to each level of
axial force defined in the first column.
* For the parameters of the curve type ‘hsv’, monotonic shear force-shear displacement
curve subjected to each level of axial force defined has to be evaluated in advance.
