Answer
The innovative structural system pioneered by Bangladeshi architect Fazlur Rahman Khan revolutionised the construction of skyscrapers. This system, often referred to as the "tube structure," transformed how buildings could withstand the lateral forces imposed by wind and earthquakes. By integrating the exterior walls and interior columns into a rigid, load-bearing frame, Khan's system allowed for the construction of taller and more slender skyscrapers, which redefined the urban skyline.
