Discussion on Field Inspection and Strengthening Method of Prestressed Beams on Roof of a Gymnasium
Prestressed concrete structures have been widely used in various construction projects due to their good crack resistance and high strength.However,with the application of a large number of prestressed concrete structures,the field inspection and strengthening of the existing prestressed concrete structure components have also developed accordingly.Taking the roof reconstruction of a school gymnasium as an example,this paper introduces the design characteristics of large-span prestressed beams,explores the field inspection and strengthening methods of prestressed beams in the proposed renovation area.It provides reference for the early detection work of relevant engineering cases.
