Experimental study on shear behavior of reinforced concrete frame column under bilateral horizontal loads

The shear behavior of rectangle RC columns with different quantity of stirrups in both principal directions were investigated based on the experiment and analysis of 2 groups of 8 specimens, in which the first group is under cyclic loading and the second group is under the monotonic load. The test results show that the failure patterns of different quantity of stirrups in both principal directions are the similar to the same area of stirrups. A three-dimensional nonlinear finite element model for test specimens were applied to the analysis of RC frame columns, and the calculated values agree well with the experimental results.
