Test Research on Spatial Hysteretic Behavior of Circular Steel Pipe
A test to study the spatial hysteretic behavior of circular steel pipe subjected to cyclic load was designed. The test setup and data acquisition system were applicable for three-dimension load. A total of 30 specimens were selected by cross section and height of the circular steel pipe to cover different slenderness ratios, different load modes. The specimens were divided into five groups by different load modes. The hysteretic curves changing with different slenderness ratios and different load modes were got after completing the experiment. These lay the foundation of the subsequent research on constitutive model about steel.
