  Hello guys,
  
  I am trying to analyse reinforced concrete under cyclic loading using the CPT model, however the solution does not run and always an unknown error obtained. Even though the solution runs while applying only axial load,but application of displacement in x direction results in error.
  
  Here are the snippet commands.
  
  ET,MATID,215
  
  KEYO,MATID,18,2
  
  MP,EX,MATID,25000 ! Define Elasticity Modulus (enter a value for E)
  
  MP,NUXY,MATID,0.2 ! Define Poisson's ratio
  
  TB,MPLA,1,,,DPC !Define Drucker-Prager
  
  TBDATA,1,31.368,36.074,3,1,40000,-40 !fuc,fbc,fut,Rt,D,sigVc
  
  TBDATA,7,2,0,2e-6,7500,2500 !R,gamt0,gamc0,betat,betac
  
  TB,MPLA,1,,,NLOCAL
  
  TBDATA,1,1600,2
  
  and following cyclic loading was applied
  
  Please provide some guidance for using CPT for cyclic loading of concrete.
