dc.description.abstractThe Commonwealth of Puerto Rico has over 2200 in-service bridges as part of their inventory and more than 50% of these bridges were constructed over 30 years ago. Seismic design requirements are updated frequently due to research and innovations, and bridges are essential structures in the transportation systems that must be designed to withstand seismic events. Because of this, the seismic analysis of bridges designed and constructed at a time when seismic design provisions were insufficient according to current standards should be considered as a required step to determine their performance and capacity to withstand lateral loads during seismic events. In this study, a detailed seismic analysis was performed on Bridge No. 2001 in Highway PR-22 over Bayamón River & Rio Hondo Channel in Bayamón, Puerto Rico. The seismic analysis of this bridge was completed following the Component Capacity/Component Demand Ratio (C/D Ratio) methodology of the FHWA publication entitled Seismic Retrofitting Manual for Highway Bridges. C/D ratios were determined for various bridge components and it was found that some of these bridge components are in need of possible retrofitting. Bridge components in need of retrofitting include: hinge connections, shear keys, piers, pile caps, piled foundations and soils. Retrofitting measures for the strengthening of these bridge components were presented, as part of this study, to improve their seismic performance as well as the seismic performance of the bridge.en_US
dc.description.abstractEl Estado Libre Asociado de Puerto Rico cuenta con sobre 2200 puentes en servicio actualmente como parte de su inventario y más del 50% de estos fueron construidos sobre 30 años atrás. Como sabemos, los requisitos de diseño sísmico son actualizados continuamente como consecuencia de las investigaciones e innovaciones y los puentes son estructuras esenciales dentro de los sistemas de transportación que deben ser diseñados para resistir cargas sísmicas. Por tal razón se considera el análisis sísmico de aquellos puentes que pudieran no estar en cumplimiento con los requisitos sísmicos actuales como un paso necesario para evaluar su comportamiento y capacidad para resistir cargas laterales durante eventos sísmicos. En este estudio se realizó un análisis sísmico detallado para el Puente No. 2001, construido a mediados de los años 70, en la Autopista PR – 22 sobre el Río Bayamón y el Canal de Río Hondo en Bayamón, Puerto Rico. El análisis sísmico se llevó a cabo siguiendo el método Capacidad/Demanda de la publicación titulada “Seismic Retrofitting Manual for Highway Bridges” de la Autoridad Federal de Carreteras. La razón Capacidad/Demanda se determinó para varios componentes del puente y se concluyó que varios de estos componentes requieren ser rehabilitados. Entre los componentes del puente que requieren ser rehabilitados se encuentran: las conexiones articuladas entre tramos, dientes de cortante, columnas, pilastras, fundaciones profundas y los suelos. Varias medidas de rehabilitación para reforzar los componentes del puente fueron presentadas como parte de este estudio con el propósito de mejorar el desempeño sísmico de los componentes así como el desempeño sísmico del puente.en_US
