STUDY ON THE USE OF CONCRETE COLUMNS IN INDOOR AND OUTDOOR SPORTS FIELD CONSTRUCTION PROJECTS IN TANGERANG CITY

In every building construction, the components of all structures must have the strength to withstand the loads they bear. Beams and columns are very important structural components in building construction. For this reason, these two structural components must be calculated and analyzed based on the appropriate combination of factored loads and forces. In preparing this research report, the author reviewed the use of concrete columns in the Tangerang City sports field construction project. This review aims to find out how much steel is used and how much concrete volume is needed for each column. From the results of the author's review, the column used in this project is the K1 column type with dimensions of 60x60 cm, with 12D25 reinforcement, with a column height of 13 m, with a volume per column of 4.68 m3, with a concrete volume per column of 4.6286 m3. So the results obtained from 70 column piles require a concrete volume of 324,002 m3, with a large mixer truck capacity of 7.5 m3, it requires 44 trucks to transport the ready mix concrete.
