Product Description

Membrane grand-standby bleacher for Nanjing Olympic Center

Total area: 2169.56 m2

The grand standby bleacher is made of pipe truss being covered with membrane roofing. Membrane structure is widely and mainly used as sports hall, museum hall, exhibition hall, airport terminal and building, storage, warehouse, large span roofing because stable support which is borne by pre-stress and reasonable design with customized beautiful appearance.

The final shape, or form, of a membrane structure depends upon:

➢ shape, or pattern, of the fabric

➢ the geometry of the supporting structure (such as masts, cables, ring beams etc.)

➢ the pretension applied to the fabric or its supporting structure

It is important that the final form will not allow ponding of water, as this can deform the membrane and lead to local failure or progressive failure of the entire structure. So we will pay attention to it in the installation.

This form of construction has only become more rigorously analyzed and widespread in large structures in the latter part of the twentieth century. Membrane/Tensile structures have long been used in tents, where the guy ropes and tent poles provide pre-tension to the fabric and allow it to withstand loads. 

The structural use of membranes can be divided into pneumatic structures, tensile membrane structures and cable domes. In these three kinds of structure, membranes work together with cables, columns and other construction members to find a form. It is same with tensile structure which is a construction of elements carrying only tension and no compression or bending. The term tensile should not be confused with tensegrity, which is a structural form with both tension and compression elements. Tensile structures are the most common type of thin-shell structures.

Most tensile structures are supported by some form of compression or bending elements, such as masts (as in The O2, formerly the Millennium Dome), compression rings or beams.

A tensile membrane structure is most often used as a roof, as they can economically and attractively span large distances. Tensile membrane structures may also be used as complete buildings, with a few common applications being sports facilities, warehousing and storage buildings, and exhibition venues.
