Comparación del efecto P-Delta en edificaciones de hormigón armado con columnas regulares e irregulares

Abstract

The P-Delta effect is a non-linear secondary analysis, which is the product of the application of an axial load to structural elements, whose analysis becomes complex in tall structures and slender sections. In this work, a comparison of the incidence of regular (rectangular) and irregular (type L) columns on the P-Delta effect in a reinforced concrete building was made. This building was analyzed with a structural design software based on the NEC 2015 standard. During the design and modeling process, dimensions of beams and columns were optimized in both directions, as well as the amount of steel, to finally obtain the drifts of each floor. With the results obtained, differences were established in floor drifts, which are a consequence of the geometry and reinforcement of the proposed elements.
