La presente investigación, desarrollará la interacción dinámica suelo estructura IDSE con y sin amortiguamiento aplicado a 3 modelos denominados modelo A, modelo B y modelo C con 4, 8 y 12 pisos respectivamente. Estos modelos serán evaluados en tres tipos de perfiles de suelo S1, S2 y S3 con características (peso específico, coeficiente de poisson y carga admisible) obtenidas de los libros del Sr. Braja M. Das y Willian Rodriguez Serquen. La evaluación de la IDSE se realizará mediante las ecuaciones simplificadas propuestas por la Norma Americana (EEUU) NIST GCR 12-917-21 Soil-Structure Interaction for Building Structures donde se desarrolla la interacción inercial que se hace referencia a los desplazamientos y rotaciones en la base de la estructura (fundación) debido a la respuesta de la estructura cuando da lugar un sismo. Asimismo, la flexibilidad de la fundación y suelo son representados mediante 6 rigideces (3 de traslacionales y 3 de rotación) con y sin amortiguamiento. Para cada modelo se realizará una comparación de cortante basal, momento, desplazamientos, derivas, periodos, frecuencias, modos de vibración, fuerzas internas máximas, y fuerzas internas en un pórtico con la finalidad de observar el comportamiento de las estructuras en los distintos tipos de suelo y tamaños de las modelos propuestas.

Current practice in seismic design often assumes free-field conditions for the estimation of liquefaction-induced building settlement. This is inaccurate, as a structure places additional stresses on the soil, resulting in changes to the spatial and temporal occurrence of liquefaction, accelerations, and deformations. Further complications arise in dense urban environments where closely spaced structures may interact through structure-soil-structure interaction (SSSI). Previous studies have shown that SSSI may have positive or negative effects on the response of adjacent structures in terms of permanent settlement, rotation, and flexural deformations. However, little is known regarding how to maximize the benefits of SSSI with minimal risk of adverse consequence. In this study, centrifuge tests were conducted on both isolated and closely spaced structures to identify how the building separation and ground motion characteristics affect the response of adjacent structures founded on a layered, liquefiable soil profile. Results indicate that properly planned configurations and interactions may be employed in combination with traditional mitigation strategies to improve the settlement-rotation response of adjacent structures, while also reducing the demand imposed on the superstructure.

<p>The state and the arts of research on foundation buried depth effect on building structures are reviewed and summarized in detail from such aspects as static response property and dynamic response property, and a brief discussion is carried out on the future developments and studies. Different scholars have conducted research for this aspect of the issue; the conclusions vary because of differences in the conditions of the upper structure stiffness. Superstructure should consider different stiffness conditions a lot of numerical calculations, foundation depth summary obtained reaction influence on the dynamic characteristics and dynamic soil structure interaction system of law.</p>
