摘要

An official building is a five-floor RC frame structure. Because of the architecturernchange, a new floor will be added. The added structure is prestressed cable structure. In this paper, thernprestressed cable structure is accounted briefly first, then the construction period is simulated by thernFEM software. The structure’s deformation and stress due to different load cases is calculated, so therninitial cable stress can be determined. To study this type of structure, one prestressed cable structure isrntested for the construction period. At the end of the paper, the construction technology of prestressedrncable structure is accounted, including the cable prestressing technology, stress monitor technology.rnAnd also the special equipment for prestressing technology can be referenced by other similarrnprojects.
