<t>Dear Rui,<br/>
<br/>
I agree on both points. The use of different materials in the sections definition was not the best, since both the cover and core concrete were essentially the same material with different confinement level.<br/>
The discrimination of cover and core area in the criteria ...

<t>Thank you Zoi,<br/>
<br/>
This was exactly my point. The previous version 6.5 had different criterion types for "Cover material strain" and "Core material strain", therefore I assume that each criterion referred to the strain of different fibre areas of the section. <br/>
That is why it seems ...

<t>Hello Zoi,<br/>
<br/>
Thank you very much for your help. I'm sorry i am consuming your time like this, perhaps I was not very clear previously.<br/>
<br/>
Lets suppose that I want to set a criterion for concrete strain to check crushing of concrete core using the proposed value: -0.006.<br/>
When ...

<t>Dear Zoi,<br/>
<br/>
The previous version had different criterion type to detect concrete strain at the core and the cover area. My understanding was that when the criterion was referring to the core, then seismostruct would read the strain values from the confined concrete area. On the other ...

<t>In previous version 6.5, it was possible to determine performance criteria specifically for concrete cover. This way it was possible to detect concrete spalling, if the predefined strain limit was reached. I assume the program would read strain levels at the cover area (outside the section core ...

<t>Dear Rui,<br/>
<br/>
I am sure that Seismostruct developers are checking the posts in all forum sections. I was just referring to the tutorial issue, that is just a detail of this discussion and could easily be overlooked. <br/>
I agree with the need of simplicity in the beginners examples ...

<t>Dear TUC,<br/>
<br/>
Thank you for your very useful comments. I agree with all your considerations regarding the co-existence of fiber modeling and rigid diaphragms, I believe there is a also a related warning in the Seismostruct manual. <br/>

During pushover analysis, application of forces ...

<t>Dear huffte,<br/>
<br/>
Thanks once again for your valuable contribution. I am not suggesting that this a Seismostruct fault, I am just skeptical regarding the accuracy of combining pushover analysis with fiber based sectional behavior in general, without taking any precautions/limitations to the ...

<t>I have a question regarding the implementation of pushover analysis in RC structures and the consequent inelastic behavior of beam elements.<br/>
<br/>
If we consider a 2D frame subject to pushover analysis, when the horizontal force is imposed at one end of the structure, the gradual increase of ...

<t>When I am running an analysis I can see the frame forces diagrams with their respective values on the diagram. Yet, many times, when I change to view another result (e.g. hysteretic curves, global parameters) and then return to the Frame Forces Viewer, the values are gone and won't reappear even ...
