Italian to English Tech/Engineering Architecture

Hi, I'm translating a project description on a website and I came across the above sentence. I can't find a good solution for 'setti'. In Italian it has a very specific connotation, namely "elementi verticali quali pareti in cemento armato, che data la loro massa e la loro elevata inerzia hanno il compito di contrastare le forze sismiche orizzontali o la spinta del vento". It is also different than 'wall' according to this page http://forum.acca.it/it/edilus/id11207/differenza-fra-setto-...
I might settle for "sturdy blind wall" but I wanted to ask you guys first.
Can anyone help please?
