i need to model bonded and unbonded post tensioned concrete beams using ANSYS APDL V19. i want to exactly model the bond slip behaviour for these beams.

for bond between concrete and prestressing strand some authors had taken combine element (target 170 & contac174), few had taken combine 39 element and few had taken cobine 14 element. now for ansys V19 which one correct to use.

since they are using these elements to both bonded & unbonded tendons then what is the difference between them & how they model it, i need clear explanation. 

my final request is how can i model bonded & unbonded strand behaviour in ANSYS APDL V19. if possible please provide step wise procedure in GUI manner.
