En el estudio, se evaluaron las conexiones soldadas RCFT en pórticos a momento con el objetivo de analizar su comportamiento bajo cargas sísmicas y gravitacionales. Para ello, se realizaron simulaciones numéricas mediante el método de elementos finitos utilizando el software IDEA StatiCa, el cual permitió modelar tanto las placas base como los pernos de anclaje y las uniones soldadas. Se analizaron las tensiones y deformaciones generadas en las conexiones y se verificó su comportamiento frente a las normativas AISC 360-16 y NEC-15. Los resultados mostraron que las conexiones RCFT distribuyeron adecuadamente las tensiones y presentaron un comportamiento satisfactorio frente a momentos flectores y fuerzas de compresión. Asimismo, las derivas por piso se mantuvieron dentro de los límites establecidos por la normativa, lo que garantiza la estabilidad estructural de las edificaciones bajo eventos sísmicos. En conclusión, las conexiones soldadas RCFT optimizadas mediante el método de elementos finitos son una solución efectiva para mejorar la seguridad y resistencia de las estructuras en zonas de alta sismicidad.

Abstract
In this study, welded RCFT connections in moment frames were evaluated with the objective of analyzing their behavior under seismic and gravitational loads. Numerical simulations were carried out using the finite element method with the IDEA StatiCa software, which allowed the modeling of base plates, anchor bolts, and welded joints. The generated stresses and deformations in the connections were analyzed, and their performance was verified against the AISC 360-16 and NEC-15 standards. The results showed that the RCFT connections effectively distributed the stresses and demonstrated satisfactory behavior under bending moments and compressive forces. Additionally, the inter-story drifts remained within the limits established by the regulations, ensuring the structural stability of buildings during seismic events. In conclusion, RCFT welded connections optimized through the finite element method are an effective solution to improve the safety and strength of structures in high seismicity areas.
Keywords: welded connections, RCFT, finite elements, moment frames, seismic-resistant design.
