The article discusses the most common types of modified columns in Mexico: composite section columns, high-strength concrete columns, prestressed concrete columns. The procedure for calculating columns and new proposals to improve construction efficiency is described. Columns are one of the most important elements of orthogonal frame buildings, so improving their designs requires special attention. In composite section columns, using high-strength concrete in the outer zone, the strength of the concrete located in the core increases 1.5 times more, which significantly increases the efficiency of the structure. Columns made of high-strength concrete have an increase in efficiency when used in high-rise buildings. Prestressed concrete columns are very effective because they have high resistance to load, they are able to withstand significant stresses.

Keywords: concrete, reinforcement, reinforced concrete, high-strength concrete, prestressing, columns, columns of composite section, eccentricity, stress, deformation
