Performance Assessment of Hollow RC Column with Diagonal Bracing

Abstract

Hollow concrete columns 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. And achieving a good degree of strength and ductility. The purpose of this study is to assess the structural performance of hollow column with diagonal reinforcement. Hollow sections are often used for tall bridge columns to reduce their mass, reduce seismic inertia forces, and reduce foundation forces. However, the seismic performance of hollow columns is still not fully understood although a few experimental works were conducted previously. There are several interesting areas which must be investigated for the hollow columns, i.e., ductility capacity, shear strength, effect of diagonal loading in square section. This report presents the flexural ductility capacity of the hollow circular columns with diagonal reinforcement placed near the outside face of the section. And achieving a good degree of strength and ductility. The purpose of this study is to assess the structural performance of hollow column with diagonal confining reinforcement.
