“…The test variables were the transverse steel ratio, longitudinal steel ratio, arrangement of the transverse steel, existence of the longitudinal steel near the inside wall face, hollow ratio, and axial force ratio. Prado et al 9 evaluated the arrangement of transverse reinforcement in hollow piers subjected to lateral load. Cassese 10 proposed a modeling approach for existing shear‐critical RC bridge piers with hollow rectangular cross section under lateral loads.…”

The bridge piers are the main components, and their destruction can cause significant damage to bridges. The concentration of failure in one or two piers of irregular bridges has led to challenges in codes and studies regarding the simultaneous failure of the substructure components. The RC hollow sections are structurally adequate for application in isolated bridges with unequal pier heights due to their large strength/mass and stiffness/mass ratios. In the previous studies, the isolation devices have been used to produce uniform lateral stiffness for different pier‐isolator systems of bridges with unequal pier heights. However, this approach leads to the flexural moment concentration in the tall piers and extra ductility demand in the short‐pier isolators. This article presents a new performance‐based design method for isolated hollow RC piers with irregularity in height to provide uniform performance along the bridge. The target performance level is achieved by proper selection of the characteristics of LRBs and pier cross‐sections. This method is used for two continuous span bridges with slight and severe irregularities, and the responses are compared with other design methods. The results show that the proposed method produces similar performance levels in all piers, besides uniform ductility demand, uniform shear strain, and simultaneous failure of all LRBs. Furthermore, the damage probability of tall piers decreases and gets close to that of the short ones.

Hollow concrete columns (HCCs) reinforced with steel bars have been employed extensively for bridge piers, ground piles, and utility poles because they use fewer materials and offer higher structural efficiency compared to solid concrete columns with the same concrete area. Many experimental studies have been conducted to investigate the behavior of HCCs under different loading conditions and found that the structural performance of HCCs is critically affected by many design parameters. If not designed properly, HCCs exhibit brittle failure behavior, due to longitudinal bars buckling or the concrete wall failing in shear. In addition, the corrosion of steel bars has become an issue in reinforced-concrete structures. Therefore, this paper critically reviews the different design parameters that affect the performance of HCCs and identifies new opportunities for the safe design and effective use of this construction system. Moreover, the use of GFRP bars as reinforcement in hollow concrete columns is explored with the aim of developing a non-corroding and structurally reliable construction system.
