Trying to perform PSC design in a model I have received this error “Different type of tendon material exists within the Tendon Group.”
As you see below, different tendon properties are used in the same tendon group. This is not allowed for the PSC Design. These two tendon profiles are assigned to two different girder and, thus, these two tendons should not be assigned to the same tendon group. You need to make it different tendon groups.
