Abstract:
In view of the simply supported hollow slab common diseases,such as horizontal contaet due to thelack of hollow slab delleetion inereases , single plate bearing and other problems, with the finite element soltware ,a simulation study was carried out for the hollow slab bridge ,extemal prestressing steel reinforeement olthe. Change of displacement of strueture before and after applying transversely prestressing assembly type hol.low slab bridge through eomparison and analysis ,to analyze the elleet of reinforeement theory ,and diseusses thetransversely prestress ean improve the whole bridge. The beam boltom transversely preslressed reinforeementfor assembly type hollow slab is verified , transversely load distribution cean improve elfeetively ,inerease the hol.low plate struclure of transversely eonneetion ,thereby reducing the phenomenon of stress of single board.
