This document summarizes the preliminary sizing of columns for a construction project in Porlamar, Venezuela. It provides calculations of the required cross-sectional area for several corner columns, edge columns, and one central column based on the axial load capacity and concrete compressive strength. The corner columns require a minimum cross-sectional area between 93-108 cm2. The edge columns require between 63-141 cm2. The central column requires 371 cm2. Standard column sizes are proposed for each.
