Study on Strengthening of Deteriorated Corrugated Steel Beams Using Post Tensioning
Steel beams have been a part of the construction industry since the last decades of the nineteenth century and they have gained importance due to their improved functionality compared to conventional concrete structural elements. Among various types of steel beams corrugated steel beams are special light-weight beams with corrugations at the web portions. Weight reduction aspects of corrugated steel beams aids in considerable savings in cost of structure. Corrugated beams suffer deteriorations mainly due to unexpected excessive loading and exposure to extreme surroundings. Various researches in this field suggest that the strengthening of deteriorated corrugated steel beams can be done by post tensioning techniques in the locations of deterioration. The post tensioning technique is recommended in the areas where damages are mainly due to corrosion. The deteriorations are provided at different locations of the beam. Post tensioning is achieved through reinforcement bars of suitable diameter. The result includes the ultimate load carrying capacity, total deformation, and strain and stress distribution of strengthened beams. The present study focuses on the effect of post tensioning as an innovative strengthening technique for retrofitting the deteriorated corrugated steel beams. Strengthening of corrugated steel beams is expected to increase the ultimate load carrying capacity as well as improve the functional utility and life span of the structure.
