I need to define the stiffness value (K) of COMBINE 14 element for the coincidence nodes of concrete and prestressing steel (interface nodes both lies at same location), along the length directions to define the slip behaviour of BONDED & UNBONDED type of post tensioned concrete beam in ANSYS APDL.
What are the suitable two different stiffness (K) value can be input for BONDED & UNBONDED condition? What basis it can be provided?
Please provide your valuable reply at earliest possible, also provide any source of references.
Thank you all.
