dc.description.abstractPuerto Rico is located in a high seismicity zone, hence it is essential the development and implementation of state-of-the-art dynamic analysis in order to predict and prevent possible damages on structures. At present, in Puerto Rico there is a lack of a facility to conduct dynamic tests on structures that are not limited by scale. For this reason, a hybrid simulation facility is being developed at University of Puerto Rico at Mayagüez. Hybrid simulation is a technique that combines experimental tests and analytic models for evaluating the dynamic performance of structures subjected to dynamic loads. The hybrid simulation facility consists of a two channel MTS Flex Test 60 control system with quasi-static hybrid simulation capabilities. The calibration of the system was performed with the analysis and hybrid testing of a 3-story 2-bay steel frame subjected to the Canoga Park seismic record. An exterior column for the first story was tested in the laboratory at a 1:4 scale while the rest of the structure was modeled analytically using the software OpenSees and OpenFresco. Fully numerical coupled simulations were executed as a benchmark to validate the hybrid simulation facility tests. Different substructuring techniques, simplified conventional and conventional substructuring techniques, were considered in search of an efficient technique that produces acceptable results with simple experimental configuration.en_US
dc.description.abstractPuerto Rico está localizado en una zona de alta actividad sísmica por lo que es esencial el desarrollo e implementación de análisis dinámico utilizando las últimas tecnologías con el fin de predecir y prevenir posibles daños en estructuras. Actualmente, en Puerto Rico hay una falta de facilidades para llevar a cabo pruebas dinámicas en estructuras que no estén limitadas por escala. Por esta razón, se está desarrollando unas facilidades de simulación híbrida en la Universidad de Puerto Rico Recinto Universitario de Mayagüez. La simulación híbrida es una técnica que combina pruebas experimentales y modelos analíticos para evaluar el comportamiento dinámico de estructuras sometidas a cargas dinámicas. Las facilidades consisten en un sistema de control MTS Flex Test 60 de dos canales con capacidades de simulación híbrida cuasi-estáticas. La calibración del sistema fue realizado con el análisis y simulación híbrida de un pórtico de acero de 2 pisos y 3 bahías sometido al registro sísmico de Canoga Park. La columna exterior del primer piso fue probadas en el laboratorio a una escala 1:4 mientras el resto de la estructura fue modelada analíticamente usando los programas OpenSees y OpenFresco. Simulaciones acopladas completamente numéricas se realizaron como punto de referencia para validar las pruebas de las facilidades de simulación híbrida. Se utilizaron diferentes técnicas de subestructuración, como las técnicas de subestructuración convencional y convencional simplificada, las cuales se consideraron en busca de una técnica eficiente que produzca resultados aceptables con una configuración experimental simple.en_US
