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...

Thank you for your suggestion. We will consider making this change in a subsequent version of the program.

Yes, of course you can (provided that the parameters of the hysteretic curves for the hinges are correctly calibrated).

The exact conditions of the basement nodes depend on the soil profile and the adjacent buildings. You can change the boundary conditions, after you create the model with the Building Modeller.

In pushover analysis there is not a distinction between the cracked and uncracked stiffness, since the stiffness is constantly calculated and updated, depending on the current level of deformation. Having said that, in the necessary eigenvalue analysis (it is needed for the calculation of the target...

In SeismoStruct there are 30 hysteretic curves that can be used with the nonlinear link element (NLlink). Please refer to the manual or the help of the program for the specific details and input parameters on each curve. Specifically for your needs (multilinear model with strain hardening), you can ...

I am not sure that I understood what you mean. At the beginning of the analysis there is a general check of the model, before starting the execution of the actual analysis.
