Dear Opensees Community

Is there any beam column element in opensees, which is developed based on Timoshenko beam column element formulation and accepts fiber cross section with nonlinear constitutive relationships.

Thanks in advance...

Could anybody please explain what is the difference between these two functions, which I found in "FAFourSteelRCPlaneStress.h and .cpp", It seems both types are doing the same action, i.e. returning the same vector. Type - 1 : const Vector &getStress(void); const Vector &getStrain(...

Hi Many times the sever is not responsive, sometimes it is up and sometimes it is down, Please keep trying, Trying in different systems sometimes helps. Also, Please check the following information 1. Which operating system you are using?? 2. If you are using Windows, have you installed Tortoise SVN...

Dear Joshwoods Thank you very much, I Just downloaded the Opensees 3.0.0a version .exe file. I will soon let you know about the input file, status. Could you please send any two dimensional model (such as shear walls, hollow columns etc...) example input file(ndm 2), if you have any. Regards... Vijay

I think in the source code the number of macro fibers are limited to 5 downside, When I increase more than 5 no error, but when I decrease less than 5 it is happening...

Dear FMK Thank you very much. It seems, "PlasticDamageConcretePlaneStress " and "PlaneStressLayeredMaterial " are available in the latest revisions. I downloaded the source codes. I will update the status on the new materials soon. Could you please send the download details of Dr...

Dear OpenSEES Community members Can anyone tell me the meaning of the following parameters, which are defined in "ndMaterial" source code, getCommittedStrain getCommittedStress commitState What does these variables CommittedStrain, CommittedStress and commitState represents?? Thanks and re...

Dear Selim Gunay

Right now I am using a tolerance of 0.01 (NormDispIncr) and KrylovNewton Algorithm for analysis. Could you please suggest any other algorithms which can help solving the error.

Thank you

Dear OpenSees Community Members I am using "nDMaterial FAReinforcedConcretePlaneStress" for modelling a framed shear wall, I used nonlinear beam column elements to model the beams and columns and used "nDMaterial FAReinforcedConcretePlaneStress" for modelling wall elements. Joine...

Dear OpenSEES Community Members When I run the input file using the opensees executable, the program is not giving me the values I expected, there is some problem within the source code. Hence, I have no way but to understand the functioning of the source code, line by line using break points in vis...

Dear Aydindaei Eventhough the below code is written for eqrthquake, it will help you understand, implementing adaptive step size in the pushover analyses --------------------------------------------------------------------------------------------------------------------------------------------------...

Dear OpenSEES Community members I am analysing a bridge column under earthquake load, which is 29 sec long. I am using "transient" analysis command. With an adaptive step size algorithm, The maximum and minimum step sizes used in the analysis are 0.01 and 0.0001 with a decrement 0.00001. i...

Dear OpenSEES Community members

Are there any upcoming workshops happening on OpenSEES framework, My requirements are

1. Need to understand the framework, so that I can Implement my own code for elements, materials, recorders, integrator.

Thank you
