Abstract:Column plays an important role as a vertical and lateral load carrying member in building structures. In order to reduce the dimension of the lower-story columns of high rise buildings, the use of high strength materials has become an effective measure. However, most of the available experimental data on the high strength columns came from the testing of reduced-scale specimens due to the limited testing capacity in laboratory. This research reports an experimental study of 5 full-scale specimens (600×600 mm [23.6×23.6 in.]) of columns subjected to quasi-static cyclic loading under high axial load up to 0.67Ag fc˜ . The main purpose of this research is to study the confinement effect and lateral drift capacity of reinforced concrete columns made of concrete with fc˜ > 80 MPa [12 ksi], longitudinal steel with f y = 685 MPa [100 ksi] and transverse reinforcement with f yt = 785 MPa [114 ksi]. Finally, based on test observations, a design equation on the seismic confinement of column is recommended.
