dc.description.abstractA new passive control building arrangement is proposed in this investigation with the objective of improving the seismic response of structures. The proposed control arrangement was incorporated to a 1/20 scale model of a steel structure that was constructed. The SAP2000 software program was used to develop an analytical model of the constructed scale model. After using a series of experimental data to calibrate the analytical model, valuable information of the dynamic properties of the arrangement was obtained. Different configurations with distinct parameters of the control arrangement were analyzed in the program to evaluate the variables that affect the dynamic properties of the model. It was determined that the geometric configuration of the arrangement and the spring stiffness value of a spring used in the arrangement affect considerably the dynamic properties. Simulated earthquake tests were performed in two proposed alternatives of the control arrangement to evaluate their effectiveness in improving the seismic response of the scale model. It was observed that the control arrangement can effectively reduce the accelerations and base reactions of the model, but at the expense of higher interstory drift ratios.en_US
dc.description.abstractEn esta investigación se propone un nuevo arreglo de control pasivo para edificios. Un modelo a escala de una estructura de acero fue construido para incorporar el arreglo de control propuesto. Un modelo analítico del modelo a escala construido fue desarrollado en el programa de computadoras SAP2000. Luego de utilizar una serie de información experimental para calibrar el modelo analítico, se obtuvo información valiosa de las propiedades dinámicas del arreglo. Diferentes alternativas del arreglo de control fueron analizadas en el programa para evaluar las variables que afectan las propiedades dinámicas del modelo. Fue determinado que la configuración geométrica y la rigidez de un resorte utilizado en el arreglo afectan considerablemente las propiedades dinámicas. Se simularon pruebas de terremotos en las diferentes alternativas del arreglo de control para evaluar la efectividad del mismo en mejorar la respuesta sísmica de una estructura. Se observó que el arreglo de control puede reducir las aceleraciones y reacciones de base del modelo, pero a costo de aumentar la razón de deriva entre pisos.en_US
