Spatial structures refer to frameworks that are designed to support loads and resist forces in three-dimensional space. These structures can be found in various forms, such as buildings, bridges, and towers. They often utilize materials like steel, concrete, and wood to create stable and efficient designs that can withstand environmental factors like wind and earthquakes. Common examples of spatial structures include geodesic domes, cable-stayed bridges, and trusses. These designs take advantage of geometric shapes to distribute weight evenly, enhancing their strength and stability. By optimizing the arrangement of materials, spatial structures can achieve large spans and open spaces while minimizing the use of resources.
