“…For one-story structures, it is possible to implement a green roof in the northwestern part of the city. For structures with more than one story, it is not advisable because the structure, when subjected to an earthquake, can go from suffering moderate damage to severe damage and even reaching a stage close to collapse [32].…”

In recent years, seismic vulnerability in self-built housing is often seen as a problem due to the irregularity and marginalization presented, which means that informal settlements are often characterized by the difficulties of the poorest sectors to access urban land and housing, causing urban growth to have an often-violent impact on the image of the city. However, the majority of constructions houses are made of adobe material and/or noble material as one of the most representative constructive typologies of traditional architecture and local culture, for which these systems have suffered abandonment and displacement. by contemporary materials and techniques, a situation that has only increased after the recent seismic events that have occurred worldwide, whose figures are represented by percentages, due to the problems present in various countries of the world in the systematic review is considered as a primary objective determine the percentage of seismic vulnerability that affects the Self-construction of urban single-family homes, based on the analysis of research articles from the last 10 years, with a methodology that included analysis through information systems in the database such as: Redalyc , Google Scholar, Dialnet, ResearchGate and Scielo, carrying out the classification by means of the flow diagram where articles not corresponding to the subject to be investigated were discarded, being possible to obtain 50 scientific articles to work on, in the analysis it was obtained as results that most of the self-constructions present constructive deficiencies, as well as an incorrect urban planning, which contributed to increase the seismic vulnerability of the buildings.

“…En el año 2021 se publica un trabajo en el que se evidencia una disminución en el desempeño estructural de una vivienda aporticada en concreto reforzado con la inclusión de mampostería y un techo verde extensivo. Este estudio reflejó que dicha disminución sufre variaciones en función de la microzonificación del territorio analizado, afectando mayormente a estructuras de 3 niveles ubicadas en áreas que tienden a tener suelos blandos, cabe resaltar que las estructuras tomadas como referencia son de desarrollo progresivo, por lo que no cuentan con un diseño y seguimiento constructivo alineado a la normativa sismo resistente local (Contreras & Nuñez, 2021).…”

From a linear and static perspective, the increase in displacements of a structure due to the implementation of a green roof could be counteracted by increasing the stiffness of the structure. This article proposes the use of the differential evolution algorithm to optimize the equivalent stiffness of a one- and two-story-high structure by varying the green roof load under the equivalent horizontal force analysis in the Bogotá city. Through the MATLAB software, the optimization algorithm and the matrix analysis method of frame three-dimensional structures subject to compliance with the maximum drift proposed by the Colombian construction regulations are programmed and coupled. A maximum increase in equivalent stiffness of 19.25% and 57.80% (one-story structures), and of 11.12% and 32.97% (two-story structures) for green roof weights of 100 kg/m2 and 300 kg/m2 respectively, is necessary to meet regulatory requirements. It is expected that this research will serve as a starting point to generate constructive solutions for the implementation of green roofs in one- and two-story structures in the Bogotá city.
