| dc.description.abstract | Posterior al mega terremoto de Maule 2010 (8.8 Mw), se evidenciaron graves deficiencias en puentes viales chilenos, especialmente aquellos con ángulo de esviaje. Debido a esto, y con el fin de disminuir la vulnerabilidad símica de dichas estructuras, nuevos criterios de diseño sísmico fueron plasmados en el Manual de Carreteras. Sin embargo, estos no garantizan la operatividad post-sismo, afectando la resiliencia de la red vial. Esta tesis, en el marco de un proyecto FONDECYT, presenta el desarrollo y evaluación de un sistema de disipación de energía multidireccional basado en elementos U-Shaped. Se realizaron ensayos experimentales con probetas de acero tipo U, bajo protocolos de carga cíclicos, para caracterizar su comportamiento bidireccional. Los resultados mostraron curvas de histéresis estables y simétricas, sin degradación significativa. Además, se contrastaron los resultados con fórmulas analíticas, obteniendo factores útiles para diseño. Paralelamente, se desarrollaron modelos numéricos por elementos finitos, calibrados con los ensayos. Se identificaron factores CK y CFy, que permiten relacionar rigidez y fuerza de fluencia en distintas direcciones de carga. Finalmente, se simularon configuraciones de sistemas multidireccionales, concluyendo que su comportamiento puede determinarse conociendo el de un solo elemento cargado a 0° y 90°, lo que permitió proponer una ecuación de diseño para este tipo de disipadores. | es |
| dc.description.abstract | Following the 2010 Maule mega earthquake (8.8 Mw), severe deficiencies were observed in Chilean highway bridges, especially those with skew angles. As a result, and in order to reduce the seismic vulnerability of such structures, new seismic design criteria were incorporated into the Chilean Highway Manual. However, these do not ensure post-earthquake operability, thereby affecting the resilience of the national road network. This thesis, developed within the framework of a FONDECYT project, presents the development and evaluation of a multidirectional energy dissipation system based on U-shaped elements. Experimental tests were conducted on U-shaped steel specimens under cyclic loading protocols to characterize their bidirectional behavior. The results showed stable and symmetrical hysteresis curves with no significant strength degradation. Additionally, the results were compared with analytical formulas, from which useful design factors were obtained. In parallel, finite element numerical models were developed and calibrated with the experimental data. CK and CFy factors were identified, allowing for the correlation of stiffness and yield strength in different loading directions. Finally, simulations of multidirectional system configurations were carried out, concluding that their behavior can be fully determined by knowing the response of a single element loaded at 0° and 90°, which led to the proposal of a design equation for this type of dissipator. | en_US |
