A concise hysteretic model of 590 N/mm² grade high performance steel SA440 which is used in Japan for building structure is proposed. First, cyclic loading tests of steel components under constant and programmed strain amplitude are performed. Then, hysteresis characteristics are modeled by decomposing the hysteresis curve into the skeleton part, Bauschinger part and the elastically unloading part. The skeleton part and the Bauschinger part are modeled by using the monotonic test result and bi-linear model, respectively. The proposed model is examined by comparing with test results. In addition, a series of member analysis is conducted with proposed model as for the example of application.

提出了一种在日本用于建筑结构的590 N / mm ²级高性能钢SA440的简捷滞回模型。首先，在恒定和编程的应变幅度下进行钢构件的循环载荷测试。然后，通过将磁滞曲线分解为骨架部分，鲍辛格部分和弹性卸载部分，对磁滞特性进行建模。骨架部分和包辛格部分分别使用单调检验结果和双线性模型建模。通过与测试结果进行比较来检验所提出的模型。此外，以应用模型为例，进行了一系列成员分析。
