Re: FRP Material

P.S: In the above version of the paper the FRP jacket failure criterion due to buckling of longitudinal compressive steel bars was not included in FRPConfinedConcrete uniaxial material. More information could be found here:

Re: FRPConfinedConcrete uniaxial material:

Dear All,

With the help of Dr. McKenna the problems related to the convergence of FRPConfinedConcrete material in Opensees have been resolved (Source Code Modification Number 5970).

Thank you for your attention.

Kind Regards,

Kostas

FRPConfinedConcrete uniaxial material:

I have received some e-mails from other researchers/students regarding the use of the material model "FRPConfinedConcrete" that it is inserted in Opensees reporting that it is very slow and that it doesn't give any results. Therefore I was wondering if you have any idea about what is causing these p...

Re: 3D Model of one floor RC frame:

Thank you very much for your immediate reply. I understand your comment but I want just to mention that because I have imagined that this might be the case I have already tried the same geometry and connectivity with elastic elements and the static analysis runs without problem. However, I will take...

3D Model of one floor RC frame:

I have prepared the input file for a one floor reinforced concrete frame (3d model) and I run the analysis only with gravity loads and it fails. The messages I get are the following: WARNING BandGenLinLapackSolver: solve () - LAPACK routine returned 4 WANRING NewtonRaphson::solveCurrentStep () - the...
