Abstract
Esta investigación busca evaluar la vulnerabilidad sísmica de las edificaciones
escolares en Salaverry, específicamente en la I.E. N°81024 “Miguel Grau Seminario” y la
I.E.A.C Parroquial Virgen de la Puerta, utilizando el método Hirosawa. Es importante destacar
que este método es ampliamente reconocido y utilizado a nivel oficial, incluso por el Ministerio
de Construcción de Japón, para determinar la vulnerabilidad sísmica.
El fin detrás de esta investigación surge de la preocupación por la posibilidad de un
terremoto significativo que podría golpear la región costera del Perú. Por lo tanto, el objetivo
principal de esta tesis es analizar la vulnerabilidad sísmica de las edificaciones escolares en el
distrito de Salaverry, 2023. Además, se pretende realizar la modelización de estas estructuras
utilizando el software especializado en análisis y diseño de edificaciones – ETABS 2019.
Los hallazgos de la investigación señalan que la I.E. N°81024 “Miguel Grau
Seminario” no presenta vulnerabilidad sísmica en ninguna de sus direcciones ya que su índice
básico de resistencia sísmica (Is) es mayor que si índice de juicio estructural (Iso) basado en el
método Hirosawa y por medio del análisis sísmico dinámico se obtuvo los valores de las derivas
de entrepiso, siendo 0.005559, 0.006138, 0.005563 y 0.006143 en la dirección X y 0.002572,
0.002475, 0.002575 y 0.002478 en la dirección Y, las cuales cumplen con los requisitos
máximos de los desplazamientos laterales establecido por la norma E 030 asegurando un
comportamiento sismorresistente. Por otro lado, la I.E.A.C Parroquial Virgen de la Puerta
presenta vulnerabilidad sísmica en la dirección X siendo el índice de juicio estructural (Iso)
mayor que su índice básico de resistencia sísmica (Is) en su segundo nivel y el valor de sus
derivas en la misma dirección, obtenidas por el análisis sísmico dinámico, son 0.235601,
0.278741, 0.240957 y 0.296216, estando por encima de los valores establecido por la norma E
030 mostrando el carácter vulnerable de dicha edificación por lo que se recomienda a las
autoridades de la institución elaborar un plan de reforzamiento estructural para mitigar los
posibles daños ante un eventual sismo.
This research focuses on assessing the seismic vulnerability of school buildings in Salaverry, specifically at I.E. N°81024 "Miguel Grau Seminario" and I.E.A.C Parroquial Virgen de la Puerta, using the Hirosawa method. It is important to note that this method is widely recognized and officially used, even by the Ministry of Construction of Japan, to determine seismic vulnerability. The motivation behind this research stems from concerns about the possibility of a significant earthquake striking the coastal region of Peru. Therefore, the main objective of this thesis is to analyze the seismic vulnerability of school buildings in the Salaverry district by 2023. Additionally, the aim is to model these structures using specialized software for building analysis and design – ETABS 2019. The research findings indicate that I.E. N°81024 "Miguel Grau Seminario" does not exhibit seismic vulnerability in any direction, as its basic seismic resistance index (Is) is greater than its structural judgment index (Iso) based on the Hirosawa method. Through dynamic seismic analysis, the values of floor drifts were obtained, being 0.005559, 0.006138, 0.005563 and 0.006143 in the X direction, and 0.002572, 0.002475, 0.002575 and 0.002478in the Y direction, all of which meet the maximum lateral displacement requirements set by standard E 030, ensuring seismic-resistant behavior. On the other hand, I.E.A.C Parroquial Virgen de la Puerta shows seismic vulnerability in the X direction, where the structural judgment index (Iso) exceeds its basic seismic resistance index (Is) on its second level. The values of drifts in the same direction, obtained through dynamic seismic analysis, are 0.235601, 0.278741, 0.240957 and 0.296216, exceeding the values established by standard E 030, indicating the vulnerable nature of the building. Therefore, it is recommended that the institution's authorities develop a structural reinforcement plan to mitigate potential damage in the event of an earthquake.
