The most important reason for providing ties in a concrete column is to
A)increase the shear strength of a column.
B)allow the formwork to be tied to the longitudinal bars in the column.
C)prevent the buckling of longitudinal column bars.
D)increase the compressive strength of a column.
E)Ties are generally not provided in a concrete column.

Question

Quizplus · Accepted Answer

Providing ties in a concrete column prevents the buckling of longitudinal column bars. When a compressive load is applied to a column, longitudinal bars tend to buckle under the stress. Ties provide lateral support and prevent buckling, thereby improving the column's overall performance. Ties also provide a way to transmit longitudinal stresses from one bar to another and increase the overall strength of the column. Formwork ties are not provided in a concrete column as it might lead to the formation of voids in the concrete.
