dc.description.abstract | El objetivo principal de este trabajo es desarrollar una metodología que correlacione el diagrama de presión-tiempo o conocido como el diagrama de Friedländer de una carga explosiva como una solicitación externa sobre una estructura reticulada. Para este pro-yecto se considera que la estructura está siendo afectada por una explosión química, la cual, al intentar equilibrarse con el aire circundante, crea una onda de choque que se po-dría visualizar como una burbuja que impacta a la estructura. Según el FEMA (FEMA, 2003) esta onda inicia en el pico y decrece rápidamente gracias a la disipación de energía y a la divergencia de la geometría. Se realizó un análisis dinámico de la estructura por medio del programa STAAD.pro, asig-nando las cargas por medio del comando Time-History. Para el desarrollo del trabajo se plantearon 3 diferentes casos, el primero considera un edificio de vivienda con sus 3 di-mensiones similares, en el segundo caso se considera un edificio de oficinas donde altura es aproximadamente el doble de la base y en el tercer caso se considera una estructura tipo industrial donde su base es aproximadamente el triple de la altura. Estas estructuras están evaluadas con tres criterios de aplicación de carga: distribución uniforme de la pre-sión, distribución radial de la presión y distribución esférica de la presión. Resultando el criterio de distribución esférica de la presión el más preciso, que, en comparación con casos de la literatura, se encuentra una proximidad de resultados favorable.

dc.description.abstract | The main objective of this work is to develop a methodology that correlates the pressure-time diagram or known as the Friedländer diagram of an explosive charge as an external load on a reticulated structure. For this project, it is considered that the structure is being affected by a chemical explosion, which, trying to balance itself with the surrounding air, creates a shock wave that could be visualized as a bubble that impacts the structure. According to the FEMA (FEMA, 2003), this wave starts at the peak and decreases rapidly thanks to the dissipation of energy and the divergence of the geometry. A dynamic analysis of the structure was performed using the STAAD.pro program, assigning the loads using the Time-History command. For the development of the work, 3 different cases were proposed, the first considered a residential building with 3 similar dimensions, in the second case an office building was considered where the height is approximately twice the base, and in the third case, it was considered an industrial type of structure where its base is around triple the height. These structures are evaluated against three load application criteria: uniform pressure distribution, radial pressure distribution, and spherical pressure distribution. Resulting in the spherical pressure distribution criterion being the most accurate, which, in comparison with cases in the literature, finds proximity of favorable results. | eng |
