El territorio de la República del Ecuador presenta una alta sismicidad. En Ecuador el 95.9% de estructuras de vivienda son construidas con el uso de mamposterías. Se observa que entre los profesionales de la construcción en Ecuador existe un desconocimiento generalizado sobre las propiedades de los materiales constitutivos de las mamposterías y las normas para su diseño estructural. Tal desconocimiento ha generado la proliferación de construcciones que no cumplen con estándares técnicos de sismorresistencia y seguridad estructural, lo que puede generar considerables pérdidas económicas y sobre todo poner en riesgo la integridad física de las personas. El objetivo de esta investigación es determinar de manera cuantitativa la realidad local sobre el conocimiento técnico y uso de mamposterías en Ecuador. Los resultados evidencian principalmente que, el 82% de profesionales de la construcción son profesionales jóvenes; el 33.8% no supera los 30 años de edad; el 51.2% posee una experiencia profesional menor a 5 años; el 71% nunca o casi nunca realiza el diseño estructural incluyendo las mamposterías como elementos del sistema estructural; el 81% nunca recibió contenidos académicos sobre diseño estructural de mamposterías durante sus estudios superiores en Ecuador; existe un desconocimiento generalizado sobre las propiedades mecánicas de los materiales para mamposterías y la norma ecuatoriana para el diseño de mampostería estructural presenta importantes falencias.
Abstract
The territory of the Republic of Ecuador has a high seismicity. In Ecuador, 95.9% of housing structures are built with the use of masonry. It is observed that among construction professionals in Ecuador there is a general lack of knowledge about the properties of the constituent materials of masonry and the standards for their structural design. This lack of knowledge has led to the proliferation of constructions that do not comply with technical standards of seismic resistance and structural safety, which can generate considerable economic losses and, above all, put the physical integrity of people at risk. The objective of this research is to quantitatively determine the local reality of the technical knowledge and use of masonry in Ecuador. The results show that 82% of construction professionals are young professionals; 33.8% are under 30 years of age; 51.2% have less than 5 years of professional experience; 71% never or almost never carry out structural design including masonry as elements of the structural system; 81% never received academic content on structural design of masonry during their higher education in Ecuador; there is a general lack of knowledge about the mechanical properties of masonry materials and the Ecuadorian standard for the design of structural masonry has significant shortcomings.
