Behavior of RC Columns with Different Internal Ties Configurations Subjected to Axial Load: Numerical Study

Reinforced concrete columns use a lot of ties, particularly inner cross-ties in large columns. The major goal of this work is to create new approaches for horizontal reinforcement in RC columns and evaluate their effect on column behaviour. The suggested V-ties as transverse reinforcement, which would replace the cross-ties features, are cost-effective. They make it possible to complete projects faster and spend less on labour and material. Numerical study is carried out. FE models for sixty (60) specimens were developed. Each specimen is modeled with different cross-sections (250*250 mm), (500*500 mm), (1000*1000 mm), (250*500 mm) and (250*1000 mm) at different values of spacing 50 mm, 100 mm, and 200 mm. It was discovered that adopting V-tie techniques instead of traditional ties might increase column axial load capacity, reduce early local buckling of longitudinal reinforcing bars, and enhance the concrete core confined to RC columns.
