VULNERABILIDAD SÍSMICA Y LA AUTOCONSTRUCCIÓN DE VIVIENDAS UNIFAMILIARES URBANAS EN EL “MUNDO”. UNA REVISIÓN SISTEMÁTICA ENTRE EL 2012 - 2022

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.
