Herein, the sub-structure pseudo-dynamic response tests are performed with or without axial loading subjected to the ground acceleration. An exposed-type column base is a substructure portion tested. Test specimens are composed of two types of thickness of base plate. From the test results, it can be said that the ultimate state of column base is divided into two types, namely the bolt failure mechanism and the base plate failure mechanism. The hysteresis loop of thick base plate is very close to an ideal progressive slip model, and the one of thin base plate is close to degrading stiffness model. The difference of the response behavior of fictitious frame with or without axial loading is not large. However, in the case of thin base plate, the response behavior of column base with axial loading is larger than the case without axial loading. And also, the completely numerical response analysis based on typical hysteresis rules of column base is performed and compared with response test results.
