Efektifitas Kolom Dengan Tulangan Cold-Formed Type Hollow Dalam Memikul Beban Aksial

Abstract

As part of the support component in the building structure, the column is a component that bears an external load and it will give rise to axial force, bending moment and shear force along its height. Pure concrete columns can support very small loads, but their load carrying capacity will increase considerably if added longitudinal bars. Larger strength enhancements can be made by providing lateral restraints in this longitudinal reinforcement. As a result of the compressive load, the column tends not only to shorten in the longitudinal direction but also expands in the lateral direction due to the poison's effect. This research will be carried out by testing the maximum axial load until the crack occurs in the reinforced concrete column with the planning of the two looks, the 20 x 20 x 60 cm column size with the dependent variable of longitudinal steel screw and Cold Formed (mild steel) type hollow steel. The results of this study The use of the column by using screw steel reinforcement is still more effective than by using cold-formed steel reinforcement. Columns with reinforced steel reinforcement have a lower strength of 44.4% of the column by using screw steel reinforcement.
