| Abstract: |
The authors have designed to develop two types of steel and concrete (hereinafter referred to as SC, and the other OSC) composite members not used reinforced bars. The details of SC cross section are composed of steel and concrete composite section encased cruciform steel and covered by thin steel tube. On the other hand, OSC sections are composed of only cruciform steel and concrete, and the cross section shape forms an Octagon. In order to study the elastic-plastic behavior of steel and concrete composite columns under earthquake loading, 14 specimens were tested. From the experimental results, SC columns and OSC columns showed good seismic performance up to large deformation. By comparing the elastic-plastic behavior of SC columns with that of OSC columns, when used high strength concrete, SC columns have advantage due to strong confinement effect to the column confined by encased cruciform steel and steel tube. |
