Re: Modelling a rigid arm at the bridge column base

Since the effect (or not) of the elastic element depends on the stiffness that you have assigned to it, I suggest that you use a rigid link (see Constraints module) instead.

Re: Beam and wall modeling at the same floor level

I do no think that there is a tutorial describing this type of modelling; it is simply a manner of connecting different elements through common nodes or rigid links.

Re: incremental dynamic analysis (IDA)

You could reduce the size of the results file by selecting to output only some of the node and the element data (see Output page in the pre-processor). Regarding the analysis time, make sure that you are using a recent version of the program (after v2022), which has parallel analysis capabilities. S...

Re: Beam and wall modeling at the same floor level

You can easily model all these outside the Building Modeller facility, at the SeismoStruct main window, with the manual (i.e. without automation) definition of nodes and elements (with the appropriate offsets).

Re: Beam ends with variable support conditions

Not really. SeismoStruct is not a program specialized in the modelling of loading phases. Elements with different activation and deactivation times is the only thing we could also think for this purpose.

Re: Linear Dynamic Analysis (LDA) - Modal Combination

The modal combination rule employed is CQC. Regarding the modes used in the combination, SeismoBuild considers adequate modes, so that the sum of the effective modal masses is greater 90% of the total.

Re: Center of mass & center of stiffness

Unfortunately, with the current release it is not possible to get the exact coordinates of the center of mass and stiffness of the model.

Re: zero diagonal error in 2d model

An eigenvalue analysis, if it converges, will give you a good insight of what is wrong with the model. If you check the modal shapes will be be able to see what is connected and what is not in your model.

Re: Apply Cyclic Load in Static Time-history Analysis

This is probably an error of the program that must have been fixed in the more recent releases.
Please download the most recent v2024 release and try running the model. If the problem persists, please send the model to support@seismosoft.com

Re: Linear Dynamic Analysis (LDA) - Modal Combination

No, unfortunately such settings cannot be changed manually in SeismoBuild. This can be done only in SeismoStruct.
