The purpose of this paper is to focus on analyzing its flexural capacity under concentrated force at the two points of a symmetrical load after the 21 old and new different degrees of damege to prestressed concrete hollow slab is strengthened with CFRP by the different paste modes and paste quantities.Meanwhile,according to the initial loading of prestressed concrete hollow slab specimens in which the plastic state, based on the elastic-plastic theory,it presents the theoretical calculation formula of the ultimate bearing capacity produced with the consideration of the secondary load of the prestressed concrete hollow slab strengthened with CFRP.Through the experimental value of the old and new specimens compared with the theoretical one, It provides design suggestions and reference for the prestressed concrete hollow slab strengthened with CFRP,and provides an experimental basis for the repairing and reinforcing practical application of the Wenchuan disaster area.
