Material Use and Efficiency in Ultra-Thin Towers
Compared to 20 years ago, a new class of ultra-slender skyscrapers are emerging. These towers, sometimes called “pencil towers," are constructed at aspect ratios greater than 10:1 and are at least 985’ (300m) in height. This thesis looks to determine the material excess typically required for such …
