Shear hinge modelling using LimitState model

[ashutoshsonpal]

In the LimitState model for shear failure by Elwood, the sample code given on the website uses the following code to define the shear properties:
----------------------------------------------------------------
element zeroLength 3 3 4 -mat $shearTag $axialFailTag $centerSlipTag -dir 1 2 6
---------------------------------------------------------------

(1) Can anyone please explain why the shear limit tag is associated with local x-direction rather than the local y-direction?

(2) Also, it would be great if someone could explain the pushover analysis they have carried out (load control integrator with a "sp" type loading at the top).

Thanks,
Ashutosh

Hi
Did you find how to model shear hinge ?
Can you explain how it is done?

These directions are the global directions and local axes. Shear limit tag is assigned to the horizontal direction.

Hi
Can you provide any example how to provide both shear hinge and forceBeamColumn element and integrate them with section integrator?
It will be easy for me to understand by going through the example
Thank you
