Abstract: In this study, a stress-strain model of fiber-reinforced polymers (FRPs)-confined concrete based on the lateral confinement stiffness was adopted to simulate the lateral response of RC columns retrofitted with external FRP jackets and tested under axial and lateral loads. The adopted model and other five-stress-strain models (established in former studies) were comparatively studied to simulate the seismic response of eight RC-circular columns retrofitted with FRP jackets and experimentally tested under both axial and lateral loads. Compared to the experimental results, the simulation results indicated that all stress-strain models could not identify properly the ultimate lateral displacements of the simulated columns. The adopted stress-strain model was revised to consider the effect of a key influential parameter (eccentricity ratio), which showed a critical impact on the simulation of the seismic response of RC-columns under combined bending and axial loadings. Finally, the proposed model was evaluated in predicting the lateral response of additional three columns and the simulation results exhibited a good agreement with the experimental results.

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

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 problems to appear when somebody is using this specific material in Opensees ?

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 a better look using the display recorder. Thank you very much again.

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 LinearSysOfEqn failed in solve ()
StaticAnalysis::analyze() - the Algorithm failed at iteration : 0 with domain at load factor 0.1
Opensees> analyze failed returned : -3 error flag

I attach the input file for your better information. Could you give me any advice in order to avoid these messages and get it done correctly?

Thank you very much for your help in advance!
