<t>Hi Muntasir,<br/>
<br/>
Given that you are looking for the Moment-Curvature relationship for the cross section, and you will be using the bending moment at the restrained end-node of the element, you should also use the curvature of the integration point (IP) that corresponds to the same end-node ...

<t>Hi Maryam,<br/>
<br/>
Whenever I wanted to get the moment-curvature response of a section using SeismoStruct I simply used a very short vertical element (let us say 0.5m), with the desired cross section, with a pair of forces on top (a horizontal incremental one, which will assure the necessary ...

Hi Muntasir,

To apply a moment, simply use the Force type Permanent Load, choosing the moment 'direction' you want, rx, ry or rz.

Have you already registered SeismoStruct, Elena?

Hi Gonçalo,
Don't forget that the local axes for a deformed element are defined with respect to its deformed shape at the node of interest. Couldn't the difference you find come from that fact?

<t>Hi meftikal,<br/>
You can easily create a Force Dynamic Time-History Load in the Applied Loading module, which should be applied in agreement with the intended Time-History curve. You will then be able to extract the moment and the curvature in the post-processor. <br/>
All this information is ...

Hi Nicola,
Did you take a look at SeismoStruct Help System? I am sure it will be quite enough for a start-up.
Ciao,

<t>Hello there,<br/>
You should create a distributed mass element corresponding to the distributed load you wish to apply and then select the Automatically Transform Masses to Gravity Loads option present in the Settings-Gravity & Mass menu. Keep in mind that, currently, distributed loads are ...

Hi Muntasir,
Have you tried to use a link element, choosing trl_sym or trl_asym for curve type, defining, therefore, a tri-linear approximation of your moment-curvature relationship?

<t>Hi qalchatti,<br/>
The answer to your question depends a lot on what you want the FRP for. If you're just interested in providing your section with additional confinement, I would say you should increase by yourself the confinement factor of the core section.<br/>
On the other hand, if you want ...
