"Higher yield strength steel plates for bridges" that is called "SBHS" has been standardized in Japanese Industrial Standards (JIS). However, there are few studies on material properties and stress-strain relationship of SBHS. Moreover, it is necessary to grasp the feature of stress-strain relationship in the plastic range under cyclic loading of SBHS and to develop the constitutive equation in order to evaluate the elasto-plastic behaviour of steel structures made of SBHS under cyclic loading by analysis. Therefore, the tensile tests and cyclic loading tests of SBHS500 were carried out in order to earn information on the mechanical properties and to grasp the hysteretic behaviour of stress-strain relationship under cyclic loading. On the basis of the test results, the feature of mechanical properties of SBHS500 is examined and the constitutive equation of SBHS500 with high accuracy is proposed.
