The developing of High Strength Concrete (HSC) and High Strength Steel (HSS) utilization in several high-rise building especially in columns gives significant benefits. High-rise buildings that located in seismic region should resist earthquakes in the structure members (i.e., columns). Potential shear failure has to be prevented. Current design codes have emphasis on avoiding shear failure since shear failure is brittle without warning.
This research is conducted to know the shear behavior of column with high strength steel and concrete under low axial load. The low axial load is defined as 10% and 20% axial load ratio. The columns are tested under 10% axial load ratio. Parameters examined including the concrete compressive strength and spacing of the transverse reinforcement. The concrete compressive strengths of 70 MPa and 100 MPa are considered. Longitudinal and transversal reinforcements with specified yield strengths of 685 MPa and 785 MPa, respectively, are considered. This research observes: (1) behavior of the columns, (2) comparison test results and shear predictions, (3) stress of transverse reinforcement, and (4) critical cracking angle. Design suggestions are also discussed in this research.
