Lightweight Long Span Roof Structures

The sufficiently advanced stage of cast iron structures.

Lightweight long span roof structures.

Insitu rc tensioned 2. Structural steel prefabricated and installed on spot 5. Stadia sport halls olympic swimming pools ice tracks and skating rinks indoor athletics the state of the art trend on widespan enclosures. Structural fabric is a common choice for long span structures because fabric structures are lightweight inexpensive and can quickly cover large surfaces.

Precast concrete tensioned 3. Portal frame insitu rc 6. The standard length of 2 5m to 13 5m. Many long span structures such as the munich olympic stadium use fabric to create eye catching shapes not available with other materials.

All the panels are. For long span building structures 1. A x dek panel has. Water drainage layer typically gravel lightweight aggregate or profiled plastic sheeting.

Long span roofs can create flexible column free internal spaces and can reduce substructure costs and construction times. Long span lightweight reduced deflection compared to plain members opportunity to support considerable loads. Long span roof construction 4. Portal frame precast 7.

They are commonly found in a wide range of building types such as factories warehouses agricultural buildings hangars large shops public halls gymnasiums and arenas. They create internal space which are barrier free and flexible. The lightweight character of membrane is a cost effective solution that requires less structural steel to support the roof compared to conventional building materials enabling long spans of column free space. They are long span composite roofing panels which provide the necessary structural strength and stiffness and the required level of thermal insulation.

Structural steel erected on spot 4. Multi storey structures can you think of examples of buildings with long span roof construction. Long span structures are today widely applied mainly for sport buildings as. Lightweight timber roof frames can be constructed to suit any shape simple or complex using either individual timber elements stick built or trusses and can be used under metal sheeting or tiles.

They are suitable for green roof solutions and can be used as a standard panel or part of the steel structure. The lightweight structures from compression to tension. The main reasons for using trusses are.
