Re: Hysteresis graphs

So you suggest if I change the rotational response properties, I may get a lower peak?
Also I have set the plastic hinge at 50%, because the calculated PH ( originally 15%, and 10%)was causing higher peaks.

Re: Hysteresis graphs

I've ruled out these factors " material strengths, modelling of confinement, modelling of shear failures,"
Modelling of second order effects is done automatically if I've ticked that box, isn't it? I am also using FBPH, so that should not be causing it.

Hysteresis graphs

Hello,

I am doing some hysteresis verification of my own, and I notice that a constant problem is the peak forces don't match up with experimental results. The software always produces higher peaks. What could be causing that?

Re: about verification reports examples (RC joint)

Hello Speedy,

Can you share with me the how you managed to calculate the takeda curve parameters from the reference ? (Yu,2006)

I am trying to follow the mentioned equations but i am having some issues.

Re: Pinched Hysteresis Effect

I have attempted that and there is no change in the pinching effect. Are there any other factors that may affect it?

Re: Pinched Hysteresis Effect

Based on my Seismostruct knowledge, the confinement factor is automatically calculated based on the confinement selected, and I am sure of the confinement details I have entered.

Is there way to change that factor manually?

Pinched Hysteresis Effect

Hello, I am trying to do my own verification against experimental results, however, I am facing a common issue which is that all seismostruct results are very pinched at the center compared to the experimental graphs. I have tried changing the curve parameters for the steel as I have read in the man...

Re: RC beam-column joint

Was there a solution found for the original question of beam-column joint modelling?

Joint Behaviour

When Joints are not explicitly modeled using links, how does the software display their behaviour?
Can it identify failure of joints without their explicit modelling?
How can I read the results of a building's joints from the results section? Where can I find the joints response?

Unidentified section type error

I keep getting this error "Unidentified section type" When trying to graphically input my links. Works fine when i do i via the table.
