Dear all, when modelling a URM building with some "Double I type 2 section – di2" steel profiles, the following error is generated when trying to run a static pushover analysis in SeismoStruct 2023 Release-2 Build-25: """ Errors detected while sending data to solver: Analysi...

Dear all, I am planning to use the shell4n element to model flexible floors in a masonry building in SeismoStruct 2023. My question is can this element have a trapezoid or parallelogram shape or must it be always a rectangle? The information in the help system is not clear about this. Best regards, ...

Thank you for your reply. I will check SeismoStruct v2023.

Thank you for the response. I have two more questions and a request for the developers: - Is there any rule of thumb to adjust the penalty coefficients of the diaphragms for a given floor stiffness? - Going either way, it means that both the vertical loads and the inertial masses/loads have to be di...

I am currently using SeismoStruct 2021 (release 3, build 2) to model a URM building with flexible floor diaphragms. I can only find references in the user manual and examples in the sample models webpage for URM buildings with rigid floor diaphragms. Any ideas how to simulate flexible floor diaphrag...

Dear all, I am working on SeismoStruct 2021 Release 3 Build 2. I am starting to model a 3D unreinforced masonry building and I have looked again at the sample models presented in this webpage: https://seismosoft.com/seismobuild-seismostruct-sample-models/ I downloaded Structure_51 and Structure_53 s...

Dear Zoi Gronti,

thank you for pointing that out. Clearly, the information available through <F1> was insufficient.

Best regards,

Dear Zoi Gronti, thank you for your fast reply. From my tests with this input form I can see the behaviour that you mention: whenever there is I a change in the compressive strength, the modulus of elasticity changes automatically to 1000 times that value. I also gather that I cannot use a modulus o...

Dear all, I am facing a misbehaviour in the mas_par material properties input form: https://user-images.githubusercontent.com/11465815/122261048-e32d1e80-cecb-11eb-8182-45ae701d7f7b.png The modulus of elasticity keeps changing values whenever I change the compressive strength (to a value multiplied ...

Hello all, I am working on SeismoStruct 2021 Release 3 Build 2. I am starting to explore the mas_par and the mas_tl material types for the inelastic masonry frame element. Can you indicate bibliographic references for the parameters for code based checks? For instance, I cannot establish a clear rel...
