incremental load

[coppi]

Hi, I would like to know whether the pushover (adaptive and non-adaptive) can be assigned automatically to the different nodes of a frame, the various forces incremental or if I have to get them out of the software and then apply them manually.
I have got exercises carried out by Professor Pinho in 2009, which I attended, but there node incremental loads are already assigned.

I don't know if there is an automatical way to do.

I really thank you for an answer.

Hi,

SeismoStruct does not automatically assign incremental loads, since the selection of loaded nodes does require engineering judgement.

If you have to apply incremental loads to several nodes, you may nonetheless want to consider defining such loads in a spreadsheet application (e.g. Excel) and then copy and paste the data into SeismoStruct.

Sorry,
but I don't understand when you say "since the selection of loaded nodes does require engineering judgement".
In checks requests (NTC 2008 - Italian Code), I have to provide different distributions between floors (one proportional to the masses and another proportional to the modal shapes). I also think that once allocated the incremental force to the floor, I have to distribute the load among the various elements nodes according to the rigidity of the vertical elements.
In the previous post I ask you if, once given shear-base of departure for the force incremental (as prescribed in the Help), the software was able to deploy forces to the nodes as described above.

I thank you for the answer.

Hi,

We repeat that the user needs to explicitly assign the incremental loads to the nodes of interest.
