Calculation of Shear Capacity of Continuous Compound Spiral Hoop Reinforced Concrete Column

Abstract

High-ductility stirrups, which yield strength standard value is great than 1100MPa, are usually employed as a horizontal reinforcing steel bar of continuous compound spiral hoop reinforced concrete column to improve the anti-seismic performance of the short column. In this paper, a method is proposed to calculate the shear capacity of the continuous compound spiral hoop reinforced concrete column by regression analysis on the existing test data. Furthermore, the engineering application of the proposed method was illustrated in a specific case. This study provides supports for engineering projects of continuous compound spiral hoop reinforced concrete columns.
