Hi All.. Hope you all doing great.. I am in trouble of getting stress-strain data of a pushover analysis of a simple RC portal frame consisted of two columns and one beam. I have compared the pushover data with the measured experimental data. It almost matches. However, I am not getting stress-strai...

It would be a great help if you would kindly write me those extra commands or the modification I need to do to apply loads in two nodes.

Thank you so much for your cooperation.

Hi!

How can I apply pushover load in two nodes? The beam I am modeling is supposed to be loaded in two points as it is shown in the actual test. I would be grateful if anyone would help me giving the answer. Thank you.

Kind Regards

Hi! I have tried to model a simply supported beam for pushover analysis. I am facing 3 problems. If anyone could help me solve these 3 problems, I would be really grateful. Thanks. 1. in actual test they applied loads in two points. how can i apply pushover loads in two nodes? # Pushover Analysis fo...

Hello! I am facing some problems writing commands for zero length section. whenever i try to write the code for zero length section it shows error like - Warning BandGenLinLapackSolver: :solve() - LAPACK routine returned 6 Warning Newton Raphson: :solveCurrentStep() -the LinearSysOfEqn failed in sol...

I have fixed the zero length element and it worked.. Thanks a lot..

WoW..!! You are great..!!

Below is my OpenSees commands. Can you please check?

Hi everyone! I am getting this error after model building. Can anyone please let me know why this error happens? Does this comes from gravity load definition?

Thanks

Hi!

Is there any stirrup consideration in OpenSees?

Hi everyone! I have downloaded and run the following file and it shows error. But I have not modified it. I tried to run just after downloading. Examples Manual > OpenSees Example 2c.

Hi. I am trying to get moment-curvature. But I am not understanding the following commands. What do the following lines mean? Thanks.

set mu 15; # Target ductility for analysis
set numIncr 100; # Number of analysis increments
