SKYSCRAPER

The superior performance of steel structures plays an irreplaceable role in super high-rise buildings. Compared to concrete, steel structures show significant advantages in terms of seismic resistance, strength, and sustainability, making them an ideal choice for future ultra-high-rise buildings.
Steel structures have excellent seismic performance. Due to its toughness, steel is able to absorb seismic energy, greatly reducing the likelihood of structural damage. The seismic performance of steel structures is much better compared to concrete, providing a stronger guarantee for the stability of the building in an earthquake.
The strength of steel structures is much higher than that of concrete. The tensile and compressive strength of steel is significantly higher than that of concrete, which means that steel structures have a greater load-bearing capacity at the same height. In the example of a fortified 6-degree area, the height of a steel building can be about twice as high as that of a concrete building, providing more space for vertical urban development.
From a sustainability point of view, pure steel structures are more favorable than concrete. Over time, concrete buildings may reach the end of their design life and need to be demolished. During this process, the disposal and recycling of concrete may pose environmental problems, including landfill waste. In contrast, steel structures are more recyclable and can be reused through furnace forging, reducing the amount of waste and meeting the concept of sustainability.
The choice of steel over concrete for ultra-high-rise buildings is based on steel's excellence in various aspects such as seismic resistance, strength, and sustainability. Its high load-bearing capacity, fast construction, environmental protection and energy saving make it better able to adapt to the needs of future urban construction and provide strong support for sustainable urban development.
