Research Abstract

Main results of this study are as follows; (1) A remaining strength estimation method of severely corroded tensile plates was tried to modify with higher reliability by carrying out the tensile test for wide-width specimens. (2) A useful thickness estimation formula was proposed for the thickness measurement by using the portable ultrasonic thickness gauge. (3) Some useful knowledge for strength recovery of aged bridge were obtained by material property tests and the chemical component analyses about previous “Amarube Bridge”. (4) The mechanical influences for load-eccentricity due to corrosion were clarified by the buckling test and FEM analyses for severe corroded plates
