| Abstract: |
This paper presents the structural solution for the lifting and rehabilitation of 5 overpasses crossing a Federal Highway, located in the south part of Brazil. All structures were built in the 1960s, a period in which the design practice required a minimum height of 5,0 m to allow the flow of vehicles under the deck. Due to the recent expansion of taller vehicles and increment of traffic in the region, the highway administrator, in order to meet the space requirements of 5,5 m, financed both project and construction works. The main requirement was to carry out the entire construction without causing the interruption of traffic under the overpasses. The proposed solution included: preliminary static load tests, construction of corbels to support hydraulic jacks, localized strengthening of structural components, replacement of the originally designed fixed bearings by new elastomeric bearings and the heightening of the piers using steel plates as reinforcement. |
