Modelación experimental y analítica del comportamiento dinámico de un suelo blando
(Bogotá - Ingeniería - Maestría en Ingeniería - GeotecniaUniversidad Nacional de Colombia - Sede Bogotá, 2020-09-20)
Se realizaron cinco ensayos en mesa vibratoria de un modelo físico compuesto por un suelo blando fabricado en laboratorio con caolín y un oscilador de un grado de libertad, instrumentando el modelo con acelerómetros a lo ...
Shaking table tests of a reduced-scale rocking bridge
(Universidad de los AndesMaestría en Ingeniería CivilFacultad de IngenieríaDepartamento de Ingeniería Civil y Ambiental, 2021)
Eventos sísmicos recientes han demostrado la vulnerabilidad de tipologías de puentes tradicionales, generando altas pérdidas económicas tanto directas como indirectas. En consecuencia a esta necesidad, se ha presentado en ...
Seismic Response of Single-Degree-of-Freedom Systems with Structural Fuses
(2004-06-25)
Passive energy dissipation (PED) devices have been implemented to enhance structural performance by reducing seismically induced structural damage. In this article, metallic dampers are defined to be structural fuses (SF) ...
Seismic Response of Single-Degree-of-Freedom (SDOF) Structural Fuse Systems
(2004-06-26)
Passive energy dissipation (PED) devices have been implemented to enhance structural performance by reducing seismically induced structural damage. In this paper metallic dampers are defined to be structural fuses (SF) ...
Full-scale shaking table test and numerical modeling of a 3000-liter legged storage tank isolated with a vertical rocking isolation system
(WILEY, 2022)
This paper presents the numerical and experimental evaluation of a vertical-rocking isolation (VRI). This evaluation is done by 1-D shaking table tests performed on a full-scale legged storage tank of 3000-liters capacity ...
Construcción de una mesa vibratoria y análisis de resultados experimentales obtenidos con visión artificial
(Universidad de Cuenca, 2022-06-22)
The objective of this degree work is to determinate and analyze the dynamic properties
of Experimental Structural Models (ESM). A shaking table was designed and built to
successfully complete the objective. Then, dynamic ...
Controle ativo de vibrações em estruturas flexíveis utilizando desigualdades matriciais lineares (LMIs)
(Universidade Estadual Paulista (Unesp), 2008-02-21)
Este trabalho tem como propósito projetar controladores para aplicação em tempo real em uma estrutura flexível, objetivando a redução de vibração estrutural. Os controladores são projetados segundo o enfoque de otimização ...
Reinforcement contribution to the behavior of low-rise concrete walls
(Latin American Journal of Solids and StructuresBrasil, 2014)
Based on steel strains recorded during shake table tests of six wall specimens, the effect and contribution of steel reinforcement to peak shear strength and displacement capacity of low-rise concrete walls is assessed and ...
Estudio experimental de las frecuencias fundamentales de modelos estructurales ante sismos escalados y artificiales.
(Escuela Superior Politécnica de Chimborazo, 2021-06-29)
The instrumentation of buildings allows us to evaluate and analyze the design of an existing building, and identify possible damage after the occurrence of a moderate to severe seismic event, considering the fundamental ...
Degredation properties of reinforced concrete walls with openings
(Universidad Nacional de Colombia Sede Medellín, 2011)
This paper compares the performance of four isolated reinforced concrete (RC) walls with openings: two prototype walls tested under quasi-static cyclic (QSC) loading, and two models tested under shaking table excitation. ...
