| Abstract: | The prestressing technology has been widely used in building structures. This paper attempts to analyze the main characteristics of prestressing technology in building structures, including the realization of building large-span constructions, meeting the requirements of large-scale floor without cracks, ensuring the bending performance and the punch-resistant capability of the slab-column structures, and reaching the demands for large span and heavy load in structure conversion etc. Then, it gives some examples about the application of prestressing technology in building structures, which include large-span steel truss structures, long-span roof structures, large cantilevered truss, large-scale slab, slab-column structures and the transfer floor structures. Finally, the problems of applying prestressing technology in building structures are presented. |
