Study on the Deterioration of Shear Capacity and Failure Mode of RC Columns Subjected To High Varying Axial Force
Abstract eng: This paper was written about the deterioration of the shear strength capacity and the failure mode of columns subjected to high fluctuation axial force. Four columns designed to avoid shear failure and develop high ductility were tested under different levels of varied axial force and in unidirectional cyclic lateral loading. The failure mode is explained through the deformation behavior of the different portions all over the height of the column. Plastic analysis was employed to determine the deterioration of the shear capacity. The achieved results are as follows: in the failure mode, flexural behavior and ductility were satisfactorily developed; however, at a large lateral drift angle, the columns presented axial collapse and shear failure. The deterioration of the shear capacity was well predicted by the employed plastic analysis for these columns.
