Factory beams strengthened by bonded steel plate

Considering the obvious difference in the bearing capacity of the reinforced beam, close to 40%, the obvious weakness of the stress lag of carbon fiber, after consultation with the construction party, it is decided to strengthen by epoxy bonded steel plate.

Project overview

The five storey factory building of an industrial area in Zhuhai, Guangdong province has been overloaded because of its private rebuilding and stacking, and 10 vertical beams with cracks at the bottom of the middle beam. The span of L=9000mm, section size: 250x700mm, verified the beam bottom 4 Phi 22 (1520m m). The stirrup is 8@200~210mm, no encryption. According to the actual usage by PKPM and SATWE to calculate and check the beam bottom reinforcement to 2010m square meters, is slightly less than the stirrup. It is necessary to strengthen and strengthen. Considering the obvious difference in the bearing capacity of the reinforced beam, close to 40%, the obvious weakness of the stress lag of carbon fiber, after consultation with the construction party, it is decided to strengthen by epoxy bonded steel plate.
