How are space frame structures ideal for hangars?
Step 1: Explanation of space frame structures.
Space frame structures are structures composed of individual elements or rods that are joined together with nodes in three dimensions to form a geometrically stable framework. The resulting structure is both lightweight and incredibly strong, with the ability to span large areas without the need for additional supporting columns or walls. .
Step 2: The benefits of space frame structures for hangars.
Hangars are large, open structures with wide-spanning roofs that require the ability to support heavy loads, such as aircraft and equipment, while still maintaining flexibility to allow for easy movement and access. Space frame structures offer numerous benefits that make them ideal for hangars, including:
1. Large clear spans: Space frame structures can span hundreds of feet without the need for additional supports, making them perfect for hangars of all sizes.
2. Lightweight components: Space frame structures use individual rods or tubes which are lightweight and allow for a high strength-to-weight ratio. This reduces the overall weight of the structure, which reduces the cost of supporting structure and foundation.
3. Quick construction: Space frame structures are prefabricated, which makes for quick and easy construction on-site. Assembly requires minimal labor and equipment, making it an ideal choice for hangars where downtime must be minimized.
4. Durability: Space frame structures are incredibly durable and can withstand extreme weather conditions like heavy snow, wind, and rain. This structural system is strong enough to withstand any type of load without breaking up or requiring too much maintenance.
5. Open design: The open design of space frame structures allows for plenty of natural light and ventilation, making them a great choice for hangars where proper lighting and air circulation are necessary.
Step 3: Space frame structure examples.
One example of a space frame structure for a hangar is the 787 Dreamliner Hangar in Everett, WA. The hangar spans over 340 meters and has a maximum height of 65 meters, making it one of the largest hangars in the world. It is designed with a space frame structure, which uses a series of octagonal steel tubes connected by nodal joints. .
Another example is the Airbus A380 final assembly facility at Toulouse-Blagnac Airport, France. This hangar uses a space frame structure with over 110,000 square meters of usable floor space, making it the largest such facility in the world. Its design allows for minimal obstruction between the aircraft and personnel, which speeds up assembly and reduces the risk of accidents.
In conclusion, space frame structures offer numerous benefits that make them ideal for hangars of all sizes. They provide large clear spans, are lightweight, quick to construct, durable and have open designs that provide adequate lighting and ventilation. Two examples of such structures are the 787 Dreamliner Hangar and the Airbus A380 final assembly facility.
