Tube structures are architectural designs that utilize hollow, cylindrical shapes to create strong and lightweight frameworks. These structures are often made from materials like steel or aluminum, which provide durability while minimizing weight. The tube shape allows for efficient load distribution, making them ideal for tall buildings and bridges. In engineering, tube structures are commonly used in the construction of skyscrapers and towers. Their design helps resist bending and buckling, ensuring stability under various forces, such as wind and seismic activity. This innovative approach has made tube structures a popular choice in modern architecture and civil engineering.
