Hello everyone,
I once did incremental dynamic analysis with the 0.0001 displacement and rotation tolerance for Displacement/Rotation based criterion and once with the 0.00000001 and the results were quite different (for example, the Max inter-story drift was close to zero for the 0.0001 criterion ...

Have you selected the "Restrain All" restraint type for all the support nodes? If yes, could you please send me your model at z.gronti@seismosoft.com to check it?

Dear z.gronti,
yes I did. I sent you the files. Thanks a lot

Hi everyone,
I did an incremental dynamic analysis of a 4-Story steel frame, but for scale factors of 0.4 and above some of the records, relocation of the support in deformed shape post-processor is observed. Is this normal? The supports are fixed and all members are infrmDB. (I changed the members ...

Hi everybody
I downloaded the record from Peer. Each Time Series Records has two horizontal components(H1,H2).There are two maximum accelerations for each component(PGA1,PGA2). To scale it, it is necessary to divide the components of each into the maximum acceleration (max(PGA1,PGA2)). I want to ...

Hello to all dear users,
Is it possible to calculate the height of the building from the period obtained from the eigen value analysis in Seismostruct?

I read an article([https://www.scielo.br/j/lajss/a/jjmyXQkR5tpJ7WXKQ5xG8Zs/?lang=en) in which the structure was analyzed by the Seismostruct, but ...

In order to calculate the total overturning moment at the base you need to consider the moments and the individual supports, as well as the moments from the axial loads on the columns, M=(Force)x(lever-arm).

Hi
Is it possible to determine the position and order of formation ...

Could you not use the 'css' section and remove all longitudinal reinforcement? And you could set the transverse hoops to something extreme (say, 2mm bars spaced at 2 meters) to effectively eliminate their influence. It seems you could further reduce the influence of any reinforcement by specifying ...

Dear aliisaberiiii,

Could you please explain what do you mean by "it does not exist"? The sections I mentioned are available in SeismoStruct v2021.

Yes, you may use two sections, as you described, connected to the same two end nodes.


Dear z.gronti,
There are only composite sections with ...

Dear aliisaberiiii,

There is a number of composite sections available in SeismoStruct. Probably the Composite rectangular or circular section might cover your modeling requirements.


Unfortunately it does not exist.
Can two sections be used for one column at a time? One is a steel rectangle ...
