I don't think the “Vierendiel” principle was involved. That, of course, is simply the rigid frame with strenthened corners substituting for diangonals. I confess I don't understant the WTC principle fully, but suppose that the tube of the outer shell itself, so some degree (since the towers were fairly narrow) plus the core were intended to resist horizontal forces. But the floor trusses, I suppose, were not designed as rigid frames but as simple beams with (in effect) pin connections, as the dampers seem to suggest.
Your other point is well taken, however. We do tend to regard diagonals and odd angular forms as "agitated," rather than serene. You don't have to be Japanese to prefer serenity.
