Capacity Calculation on Reinforced Concrete Beams Strengthened by Externally Prestressed Transverse Tensioning Method

Eight reinforced concrete beams (six externally reinforced and two contrast beams) were tested under the primary or secondary load experiment. According to the test results, the existing formulas and specifications were applied to make calculations on reinforced beams. Besides, comparisons were made between test and calculation value, the differences were pointed out and improvement measures were proposed. Comparisons were made between test and calculation value on normal section flexural bearing capacity of reinforced concrete beams strengthened by externally prestressed transverse tensioning method and they are in good agreement.
