Abstract
El presente trabajo de investigación se llevó a cabo en la ciudad de Trujillo, Perú,
con el objetivo de determinar el comportamiento sismorresistente de los sistemas
estructurales diagrid y de muros estructurales en una edificación de 18 pisos. Para alcanzar
este objetivo, se adoptó un enfoque de diseño no experimental, transversal y descriptivo, que
implicó el análisis de dos poblaciones. La primera población consistió en una edificación de
18 pisos con sistema estructural diagrid, variando el ángulo de diagrid en cinco modelos
diferentes. La segunda población se basó en el uso del sistema de muros estructurales como
punto de comparación. La metodología de recolección de datos comprendió la revisión
documental y la observación indirecta, utilizando fichas de resumen y guías de observación
como instrumentos de recopilación. La estadística descriptiva se empleó como técnica de
análisis de datos. El estudio se centró en la problemática de la falta de sistemas estructurales
modernos en el país que sean compatibles con las exigencias de la ingeniería estructural a
nivel mundial. Se señaló que la persistencia en el uso de sistemas estructurales
convencionales se debe a la falta de conocimiento y divulgación de sistemas más modernos,
como el diagrid. Los resultados del estudio revelaron que el sistema estructural diagrid Tipo
3 con un ángulo de 60.95° logró una aceleración de 1.20 m/s², en comparación con la
aceleración de 1.91 m/s² obtenida para el sistema de muros estructurales. Asimismo, se
observaron desplazamientos máximos de 25.30 mm y 51.99 mm, respectivamente. En cuanto
al consumo de material, se identificó una disminución del 11.10% en la cantidad de concreto
y del 32.76% en la cantidad de acero en el sistema estructural diagrid en comparación con
el sistema de muros.
The present research work was carried out in the city of Trujillo, Peru, with the aim of determining the seismic-resistant behavior of diagrid structural systems and structural wall systems in an 18-story building. To achieve this objective, a non-experimental, cross-sectional, and descriptive design approach was adopted, which involved the analysis of two populations. The first population consisted of an 18-story building with a diagrid structural system, varying the diagrid angle in five different models. The second population was based on the use of structural wall systems as a point of comparison. Data collection methodology included document review and indirect observation, using summary sheets and observation guides as data collection instruments. Descriptive statistics were employed as a data analysis technique. The study focused on the problem of the lack of modern structural systems in the country that are compatible with global structural engineering requirements. It was noted that the persistence in the use of conventional structural systems is due to a lack of knowledge and dissemination of more modern systems, such as the diagrid. The study results revealed that the Type 3 diagrid structural system with an angle of 60.95° achieved an acceleration of 1.20 m/s², compared to the acceleration of 1.91 m/s² obtained for the structural wall system. Additionally, maximum displacements of 25.30 mm and 51.99 mm were observed, respectively. Regarding material consumption, a reduction of 11.10% in the quantity of concrete and 32.76% in the quantity of steel was identified in the diagrid structural system compared to the wall system.
