Influence of ties on compressive strength of concrete piers

The experimental testing of the effect of ties on the compressive strength and deformability of centrically loaded concrete piers of rectangular cross-section is presented. The authors present the way in which the ultimate bearing capacity and deformability of piers are influenced by concrete strength, and by the spacing and area of ties. The results show that the ultimate bearing capacity and the ultimate shortening of tested piers increases with the increase in the quantity of transverse reinforcement. At that, the tie spacing, rather than its thickness, is of primary significance.
