Toltén Bridge’s response under extreme conditions analysis through numerical models

This article presents the structural health analysis of a full-scale vehicular bridge, using a twin model calibrated with experimental information. This structure consists of concrete arches, built more than 80 years ago, and reinforced in the 1990s with a steel structure. Different load combinations were evaluated in this model to determine the strength of the structure according to current design standards. Finally, it was found that several of its components do not meet the current design requirements, putting the structure in a vulnerable condition to seismic hazards and restricting its service to traffic loads

Análisis comparativo en la respuesta lineal de sistemas estructurales muro-pórtico representativos de Bucaramanga incorporando interacción suelo estructura

This paper evaluates the influence of Soil-Structure Interaction (SSI) on the linear structural response of regular wall-frame systems representative of Bucaramanga-Colombia using the substructure approach proposed by Winkler. Information was collected from existing local systems study using official databases. Using the 22 factorial design of experiments, nine artificial buildings were created with different soil types and number of floors. These buildings were designed and detailed under the fixed base idealization, following the local seismic-resistant regulations. Analyses were carried out including and excluding the ISE. The results revealed that the ISE had a significant influence on the linear response of structures located a high seismic hazard zone, presenting variation in the fundamental period, change in the modal response, increase in drifts and decrease in the base shear. In addition, it was found that it also affects the analysis method for the design.El presente artículo evalúo la influencia de la Interacción Suelo – Estructura (ISE) en la respuesta estructural lineal de sistemas muro-pórtico regulares representativos de Bucaramanga-Colombia utilizando el enfoque de subestructura propuesto por Winkler. Se recopiló información de sistemas locales existentes utilizando base de datos oficiales. Mediante el diseño de experimentos factorial 22, se crearon nueve edificios artificiales con diferentes tipos de suelo y número de pisos. Estos edificios fueron diseñados y detallados bajo la idealización de base fija, siguiendo la normativa sismorresistente local. Se llevaron a cabo análisis incluyendo y excluyendo la ISE. Los resultados revelaron que la ISE tuvo influencia significativa en la respuesta lineal de las estructuras ubicadas en zonas de amenaza sísmica alta, presentando variación en el periodo fundamental, cambio en la respuesta modal, incremento de derivas y disminución en el cortante de base. Además, se encontró que también afecta el método de análisis utilizado para el diseño.
