Silos are vulnerable structures during severe seismic events due to their slenderness and their interaction with stored material. This investigation presents the results of a special structure that incorporates a basal seismic isolation system, such as the Triple Friction Pendulum System (TFPS). A parametric study was conducted on eight models of reinforced concrete silos to evaluate the effectiveness of TFPS isolators in mitigating the effects of various parameters on their seismic response. This research makes significant contributions by identifying parameters that affect isolated silos, providing valuable insights into their seismic behaviour. The silos were modeled and validated by comparing the forces obtained from a modal spectral analysis with analytical forces from a previous study, achieving acceptable errors for the research objectives. Finally, a nonlinear dynamic time histor...

Reinforced concrete exposed to high temperatures, such as in a fire, poses a serious threat to buildings by weakening the concrete and reducing the structure's stiffness. Therefore, the article investigated the structural behavior of reinforced concrete when subjected to elevated temperatures in Peru, where many structures are not designed to withstand high temperatures, leading to irreparable damages such as loss of human lives and changes in material properties. To enhance the heat resistance of reinforced concrete, carbon fibers were added, and a percentage of ultra-high-strength concrete was incorporated. The material was analyzed using the finite element method. Different frames were evaluated, focusing on the use of matrices and nodes. The proposal involved adding new materials; carbon fibers were added at 0.06%, and ultra-high-strength concrete at 20%. These quantities were chosen...
