Double tees may be used for many types of buildings.

Prestressed concrete roof structures.

Concrete roof systems have three basic advantages over competitive materials esthetic appeal structural economy and functional utility. Precast prestressed concrete trusses were introduced in 1978 in the aci journal article titled prestressed concrete trusses. Prestressed concrete is a combination of high strength concrete and steel strands. Prestressed concrete is a form of concrete used in construction.

This combination makes a very strong structural material that is used in the building of roof slabs bridge girders and railroad ties. Double tees are the most widely used prestressed concrete product in the minimum span range. Prestressed membrane roofs have been designed since the invention of prestressed concrete. Prototype i that had a clear span of 6 1 m 20 3 ft and a depth of 0 6 m 2 ft for a span to depth ratio of 10 and prototype ii that had a clear span of 18 4 m 60 8 ft and a depth of 2 6 m 8 5 ft for a span to depth.

The article discussed two prototypes. They are described in the basic books written by pioneers of prestressed concrete. The primary prestressed concrete beams of the floor roof or like structure are first of all erected in position parallel one to another and spaced at predetermined distances apart and spanning the breadth of the structure and after this has been done elements are assembled between and in the same plane as the primary beams which extend at right angles to the primary beams and which co act. Prestressed concrete was invented and patented in 1886 by henry jackson a san.
