Due to miscalculations of post-tension losses and bending deformations, due to concrete shrinkage and creep, additional deformations were detected with arrows up to 30 cm. This implied vertical displacement of the joints in the center of the spans of between 5 and 20 cm. The principle of rehabilitation and reinforcement applied by DSI foresaw the placement of external tendons that, on the one hand, reduced deformations and, on the other, reinforced the structure. The remaining arrow could be compensated with an additional layer of asphalt. Twelve 19-0.6 "tendons of DYWIDAG were placed in each bracket, anchoring them in new concrete blocks executed within the box of the deck. With short and smooth DYWIDAG bars of Ø 36 mm the new anchor blocks were friction joined to the concrete of the web ancient. downloads Systems and Concepts for Rehabilitation and Reinforcement 19. october 2016 531.93 KB Download Plus … Projects PORTO SUDESTE IN ITAGUAÍ: DSI PREPRON PROVIDES TECHNICAL SUPPORT ...
