Yes, but you will have to make sure the node is connected to one of the structure nodes. ok then I will create a node at that point where I need to calculate the Acceleration and connect it with the near by node by a beam without applying any load on this beam. Finally, I will define a diaphragm in...

Dear Sir, Can I define some extra nodes at floor level in order to find the Floor acceleration at that node point ? Actually I need to find the Floor acceleration at Center of Rigidity. But the point where Centre of Rigidity is not lying at any node. Also, If I define any node at floor level, what s...

Do I need to use ZeroLength Element for this ???

You don't need cracked moment of inertia for fiber sections as cracking is automatically considered with the tensile stress-strain relation of concrete. If you are using beamwith hinges, you can input cracked moment of inertia for the elastic part in the middle of the beam

Thank you sir.

You can use rigid joint offsets in the geomTransf command.

Thank you sir...

Also, How to define Rigid Zone Factor ????

Sir How can I provide End (Length) offsets in Opensees as I can do in SAP2000.?
Also, I need to define Rigid Zone Factor for my Beam and Column. Is It possible to do in Opensees ???

Thanks in advance.

How to change the cracked moment of inertia in case I use Fiber section. I do get the option to change the input MOI if I choose Elastic section.

Kindly help how to implement that in fiber section

ankurjain

You mean the displacements are available until the element is removed and they become zero after the element and the node are removed. If so, that sounds normal. yes sir..ok if it is normal.... One more problem that i am facing is that ... If i do the Time History Analysis on a RC Frame analysis wi...

404 error on the github link. Is the repo private?

I'm sorry, I made the repository public. Please tell me if you are able to download the code.
It's my first time using GitHub.

regards!
yup now its working . thanks

Sir how can we input column nonlinearity like P-M2-M3 interaction for column for non-linear analysis. ??

For beam, we can assign ZeroLength Element with ModiMKPinching type Materials. But what about columns ? We need P-M interaction for that so how shall we input that data ?

You need to define masses with the mass command: https://opensees.berkeley.edu/wiki/index.php/Mass_Command or distributed mass on the elements, example: https://opensees.berkeley.edu/wiki/index.php/Displacement-Based_Beam-Column_Element. If you don't have these mass commands, your structure would n...
