In the present investigation, the influence of the irregularity of the mass and the PΔ effect on the structural behavior of a 15-story building is analyzed. The case of a regular 15-story building, 4 cases of buildings with the presence of mass irregularity in an established floor and 4 cases of irregular buildings with PΔ effect is presented. First, through linear dynamic analysis, the structural response is determined in terms of drifts, basal shear force and moment. Subsequently, the non-linear static analysis (Push over) is performed and the capacity curve of the structure is constructed. The ultimate and creep displacements are obtained from the capacity curve, and the overall ductility is estimated. Then, the seismic performance is determined for the different levels of earthquake. Finally, a comparative analysis of the structural response and the seismic performance of the cases is carried out. When analyzing the moments of the irregular structures with the PΔ effect, a variation of up to 5.60% was obtained with respect to the regular building, so that there is a greater increase in the moments when in the structural analysis of a structure with irregularity of the mass the PΔ effect is considered. An increase in the variation of the stiffness has been generated in case 1 when the PΔ effect is considered, in the x-x direction a variation of up to 73.06% and 77.76% in the y-y direction was obtained.
