Yes, I have, unfortunately it does not work

Hello,

I have a question regarding the version 5.1.0. Can it still be downloaded somewhere?
I have a big problem, because I deleted msi file and now I cannot uninstall it or install a new version.

Best regards,
Marta

Many thanks to Seismosoft support and also to Tim!
I was really curious why Lagrange Multipliers ("conceptually superior") lead to numerical difficulties in my model, but I will read some more literature to be clear about it.

Best regards!

hello seismostruct,

is there any chance that I send you my model (very simple one) to check what is wrong with the constraints? I am very curious about it...

Thank you very much for your answer. I will try to do what you recommended and if it still won't work properly, I will model connections as very stiff beams.
Best regards!

<t>Hello,<br/>
<br/>
I also have problems with constraints - rigid links.<br/>
I am modelling an arch bridge. In the model arch is defined as one beam while the piers above arch are eccentrical to it, so I have to connect them somehow. When I use rigid link (arch node is master, and base nodes of ...

<t>Maybe I didn't formulate the question properly.<br/>
<br/>
In the case of multi-support input motions, it is necessary to formulate the problem in terms of the absolute ground<br/>
motions at the different supports.So, does the program itself integrate acceleration input to obtain velocity and ...

could you please provide the formulation of the problem or give the reference (I ask because input in Seismostruct is in the form of acceleration t-h and not displacement t-h).

<t>I am sorry, I was absent for some time.<br/>

So, I wanted to match vertical components of ground motion to vertical EC spectra with 2% damping. How is it possible? If I load spectrum from file, it seems that during matching it is automatically assumed that my loaded spectrum is spectrum ...

Hello,
I am trying to define vertical target spectrum EC8 with 2% damping. Is it possible or predefined value is 5%? I tried to change it in Settings but it seems it has no effect.

Thank you in advance for help!
