My entries focused on steel arch buildings
Some of these huts are still in use today. The first Quonset huts were constructed from T design, arched steel rib members supported by wooden purlins. Design flaws soon became evident as the military began using Quonset huts for more than just troop housing and equipment storage. These uses included showers, latrines, dental offices, bakeries and isolation wards, but the huts needed special layouts to accommodate these additional uses and related equipment. The original structure was replaced with a design that employed vertical side walls supporting an arched roof; the new setup provided much more usable space.
