Mediciones de vibraciones ambientales en tres edificios de concreto reforzado de 28, 11 y 6 pisos
Ambient vibration tests on three reinforced concrete buildings of 28, 11 and 6 floors
(2016-11-21)
Se presentan los resultados de cinco mediciones de vibraciones ambientales realizadas en tres distintos edificios de San José, Costa Rica. El objetivo principal fue el medir la mayor cantidad de periodos naturales en cada ...
Model reference pi controller tuning for second order inverse response and dead time processesand science
(2016-09-06)
In this paper, a One-Degree-of-Freedom PI controller is optimized using the model reference tuning approach for a Second Order Inverse Response and Dead Time Process operating as a servo control. In addition, a graphic ...
Spectral Strong Motion Attenuation in Central America
(1994)
A bayesian regression analysis of response spectral ordinates based on 218 digitized strong ground motion accelerograms (largest horizontal component) from Central America, augmented by 62 similar, high-magnitude observations ...
Robotic architecture design to map an action language to a low level motion commands for skillful manipulation
Diseño de una arquitectura robótica para mapear un lenguaje de acción a comandos de movimiento de bajo nivel para manipulación hábil
(2019)
This paper gives an overview of a robotic architecture meant for skillful manipulation. This
design is meant to close the gap between the high level layer (reasoning and planing layer) and the
object model system (physical ...
Nonlinear behavior of reinforced concrete masonry structures
Comportamiento no-lineal de estructuras de mampostería de concreto con refuerzo integral
(2018-01)
Las estructuras que emplean paredes de mampostería se caracterizan por
tener una gran rigidez y capacidad ante cargas paralelas a su plano debido, principalmente, a la gran inercia de algunos elementos que la componen. ...
Identificación de modos de torsión empleando la medición de vibraciones ambientales y el análisis espectral en dos edificios de concreto reforzado
Identification of torsional modes using ambient vibrations and spectral analysis in two reinforced concrete structures
(2020)
En esta investigación se realizó un análisis espectral de la respuesta estructural de dos edificios de concreto reforzado, de 18 m y 56 m de altura y con distintos niveles de irregularidad en planta, al ser sometidos a ...
Processed Strong-Motion Records from the Limón, Costa Rica Earthquake of 22 April 1991
(1995-10)
Strong-motion records were recovered from 15 accelerographs at 14 stations operated by the Strong Motion Instrumentation Program of the Earthquake Engineering Laboratory (EEL) at the University of
Costa Rica (Santana and ...
Myxomycetes associated with three different types of Neotropical urban landscapes
(2022-12-05)
Urban ecology is a research field gaining momentum due to contextual pressures to study macroecological effects on biodiversity. Herein, we
evaluated the occurrence of myxomycetes in three urban Neotropical environments ...
Dynamic Analysis of Modified Structural Systems
(1987-05-20)
The subject of this study is the development of a set of methods for the calculation of the changes in the frequency of vibration and mode shape of a structure due to changes in the physical system. Such changes may consist ...
