Large span structures typically result in greater internal visibility and flow capacity with structures with spans larger than 20 meters. The most common types of long-span structures are trusses, folded plates, shell structures, frames, and tent structures or tensile structures. Large span structures has parking space generally between 300 to 350 square feet per parking space. These structures do not have intermediate columns in the parking module and offer a better level of service for people. Before you dive into a new large-span building project, it’s important to determine the best type of foundation for your building. After determining the location of the structure, evaluate the soil bearing capacity of the area where the foundation will be constructed.
