Article Preview

In this paper, a new type of large span prestressed concrete integral roof was studied. The test uses full scale specimens, the roof’s span is 24 meters, the width is 2 meters, across the tallest is 3.6 meters. The different condition of roof structure properties is examined. Through experiment obtaines the deformation and the ultimate bearing capacity of the roof, the design is proved to be correct. Test results show that the roof system with one piece casting has enough bearing capacity and rigidity. Roof destruction presents brittleness nature, destroying position is in lower chord board near the end of place. This research conclusion provides a reference data for this type of roof of popularization and application.
