I want to analyse an RCC beam wrapped with a CFRP sheet of 0.34mm thickness, what is the connection needed to be provided between concrete and CFRP sheet.

In APDL you could mesh the surface of the RCC elements with shells using the ESURF command.  The shells would share nodes with the solid elements so would be fully connected.  Typical commands would be:

nsel,s,ext   ! select the nodes on the exterior of the RCC elements

type,2       ! shell type number

secnum,2      ! shell thickness number

mat,2           ! shell modulus number

esurf         ! create shell element with the selected nodes
