Beach Hut = barraca de praia

Deck Chair = cadeira de praia

[Thomas]

For BARRACA DE PRAIA. a large one may be called a "cabana" (I think the term is common on the East Coast), and a small one might be a "shade". In California, no closed tents are permitted on the beach. People often use a style of tent that is completely open on one side.

For CADEIRA DE PRAIA, I would suggest "beach chair". The problem with "deck chair" is that a "deck" is an elevated wooden structure, much like a patio. It has nothing to do with the beach.
