“…Los resultados presentados en la Figura 4 muestran que, la FPT y el criterio H ∞ , proporcionan resultados semejantes. Asimismo, aunque aparentemente la técnica de los puntos fijos proporciona un camino menos complicado para obtener el diseño óptimo del DVA, el criterio H ∞ constituye una metodología robusta y precisa para el cálculo de los valores de diseño óptimo del DVA [16] .…”

Este trabajo se preocupa con la solución del problema de optimización H∞ para estructuras mecánicas amortiguadas de un grado de libertad (SDOF) acopladas al Absorbedor Dinámico de Vibraciones (DVA) clásico, bajo el efecto de movimientos armónicos del suelo. Con el objetivo de obtener primeramente fórmulas simples de diseño, se toma en cuenta la función de respuesta en frecuencia (FRF) de la estructura primaria no amortiguada como la función objetivo a ser minimizada en las frecuencias invariantes de control cuadradas. Para abordar esto, se aplica la técnica de los puntos fijos (FPT) basada en el enfoque de Krenk, y luego se producen soluciones cuasi-óptimas. Inspirado en la metodología de Nishihara, se calculó la medida de rendimiento de control H∞ resolviendo numéricamente un conjunto de ecuaciones no lineales, y tomando en cuenta las soluciones de forma cerrada producidas por la FPT como puntos de inicio para las iteraciones. Se observó que los puntos de resonancia de la estructura primaria amortiguada disminuyen cuando aumenta el amortiguamiento estructural. Independientemente del amortiguamiento estructural agregado al sistema mecánico, la metodología de optimización utilizada proporciona un buen compromiso para reducir con precisión los puntos de resonancia de la FRF.

“…However, most of the current studies have been conducted based on fixed base structure models [19][20][21][22][25][26][27][28], neglecting the effects on building structures using electromagnetic dampers when soil-structure interactions are considered. Soil-structure interaction refers to the additional inertia forces and additional stiffnesses resulting from the interaction between the soil and the building structure.…”

Currently, the application of electromagnetic dampers in structural vibration control and energy harvesting has become increasingly widespread. The optimization research of electromagnetic dampers in building design has also received more attention. Previous studies on vibration control of building structures with electromagnetic dampers have been conducted under fixed foundations, neglecting the effect of soil-structure interaction on building structures with electromagnetic dampers. The main contribution of this paper is to fill the research gap in the study of building structural vibration control with electromagnetic dampers considering soil-structure interaction. An effective design and parameter optimization method for building structures with both soil-structure interaction and electromagnetic energy harvesting is explored. The soil-structure interaction is taken into account, and the building model with electromagnetic dampers is improved to form a coupled vibration reduction system with both structural vibration control and energy harvesting functions. The dynamic equations of the system with both structural vibration control and energy harvesting are derived and then optimized using the H2 norm criterion and Monte Carlo-mode search method. A single-layer building structure is used as an example to study the influence of soil-structure interaction on building structures equipped with electromagnetic dampers under strong earthquake action. The dynamic response and energy harvesting of building structures under earthquake action considering soil-structure interaction are analyzed and evaluated. The results show that the influence of soil-structure interaction on building structures equipped with electromagnetic dampers needs to be considered. As the soil density decreases, the dynamic response of the building structure under earthquake action becomes larger using the electromagnetic damper system. Compared to the use of fixed foundations, the energy harvesting effect of building structures with electromagnetic dampers is weakened when considering soil-structure interactions.
