The issues with the strawberries is different than what is going on with your raspberries.

For your strawberries, we see some leaf spots which should be easy to manage. Pick off the worst affected leaves and put them in the trash. Thin the plants a bit for better air circulation.

Unfortunately the raspberry issue is much more damaging. It is a rust disease that can not be cured. This can even come from rust infected wild brambles nearby. Those plants, including their roots should be dug out, bagged and disposed of in the trash.

My apologies. I got my berry questions mixed up.

The dieback symptoms on your raspberries could be caused by one or more of a number of factors. 

This could include environmental stress, one or more diseases (canker diseases such as cane blight, spur blight, anthracnose),borers, a root problem or site issues like poor drainage. Any fruited canes left from last season that overwintered are naturally dying now too. 

The link shared above covers many of these issues.

At this point we would recommend pulling them out and if you choose to replant, choose a different location with a new bed.
