Hello, Kirkaguel and fernnie_gae, We updated today the SeismoBuild release that is currently available. In the new release (v2024 Release-1, build-5) the labels of the textboxes have been changes to Ss and S1 and now it is clear that Fa and Fv are then applied to these values. Apologies for the time...

Thank you both for your feedback.
We sent this post to the developers, they will check things and we will come back to you as soon as possible.

1) In order to increase the number of exported eigen-modes with the Lanczos method, you need to increase the number of iterations of the eigen-solver. 2) If you increase the number of modes, you will probably get the rest of the rotational mass. Note that if you have a basement the basement masses a...

Unfortunately, this printout cannot be done with the current version of SeimoBuild.

Unfortunately, this check is not included in the current version of SeimoBuild. We will keep a note for the development of a similar feature in a future release of the software.

Unfortunately, this is not possible. However, you can copy and paste the data to Excel and make the calculations there .

If you using the Lanczos algorithm, try the more stable Jacobi with Ritz transformation algorithm. Note that if you have a basement the basement masses are extremely difficult to get activated, due to the lateral supports.

You can increase the Maximum Interstorey Drift from the default 2% to a larger value (Code Requirements>Analysis Type - Lateral Load Profile)

Apart from the automatic selection of the control node, according to the requirements of the selected code, there is the possibility of the definition of the control node at the center of a specific slab (Building Modeller settings>Structural Modelling tab). However, it is not possible to directly s...
