Book excerpt: Colombia se encuentra en un complejo entorno tectónico debido a la convergencia de diferentes placas tectónicas, lo que genera zonas de subducción y rupturas corticales que han generado sismos de magnitudes considerables en el pasado. La historia reciente de Colombia se ha visto marcada por sismos como los de Popayán en 1983 y Armenia en 1999, los cuales han generado importantes pérdidas económicas además de causar cintos de víctimas mortales. Estos eventos han tenido un impacto tan importante que han servido como referencia para el desarrollo de normativas de construcción sismo resistente, para las cuales se han desarrollado estudios nacionales de amenaza sísmica con el objetivo de definir los parámetros para la construcción de espectros de diseño para edificaciones convencionales. Debido a la importancia de conocer las probabilidades de excedencia de ciertos valores de aceleración, se realiza un modelo probabilista de amenaza sísmica a partir de información actualizada referente a fallas sísmicas...

This book was released on 2012-06 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: En este libro se presenta la evaluacion de la amenaza sismica en Nicaragua basada en el metodo de la sismicidad espacialmente suavizada, tambien se presentan los conceptos basicos relacionados a la amenaza sismica. El parametro usado para determinar la amenaza sismica fue la aceleracion pico del suelo (PGA). Estos valores fueron calculados usando tres relaciones de atenuacion consideradas apropiadas para el area de estudio. Los valores del movimiento del suelo fueron calculados para una probabilidad de excedencia de 10% y 5% dentro de 50 anos. De esta manera se obtuvieron cuatro mapas de amenaza sismica para diferentes periodos de vibracion, uno para PGA, y tres mas para aceleraciones espectrales con periodos de Sa 0.2s, Sa 0.5s y Sa 1.0s para un periodo de retorno de 475 anos. Los mismos periodos estructurales fueron usados para estimar la amenaza sismica para un periodo de retorno de 1000 anos.

This book was released on 2015 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the assessment of seismic risk, hazard is one of its main components, given that, from a probabilistic perspective, provides the annual rates of exceedance of the intensities of strong motion in the site or region of analysis, or alternatively, provides a set of stochastically generated events that fully represent the hazard of the site or region of analysis. This thesis provides methodological elements of two major components of the assessment of seismic hazard: the attenuation of strong motion and site effects. A numerical procedure for the calibration of a source spectrum model to find the optimal combination of seismological parameters and derive unbiased ground motion prediction equations is presented, using available accelerogram recordings as calibration target. The source spectrum model is used to compute the radiated spectra of SH-waves for different seismic moments and hypocentral distances, combining point (far field) and finite (near field) source models. The expected value of the peak ground acceleration is computed from the radiated spectra using random vibrations theory. A genetic algorithm is used to search for the source spectrum parameters that best fit the available strong motion recordings. The procedure can be applied to any region with statistically significant accelerogram records. The proposed methodology is followed to derive spectral ground motion prediction equations compatible with the seismo-tectonic environment of Colombia, using 206 strong motion recordings as the calibration target. The obtained ground motion prediction equations are compared with those used in the latest national seismic hazard assessment study of Colombia. The comparison shows that the strong ground motion prediction equations obtained using the proposed methodology have lower residual bias, showing reasonable matching between them and the real strong motion recordings. Furthermore, in this thesis a methodology for assessing site effects in cities was developed, which is based on the geometry of the prevailing geological formations and their relation to soft soil deposits. The methodology allows to calculate the soil dynamic response at any location within a city, using a geotechnical seismic response model, which is based on the generation of synthetic stratigraphies from the definition of depth profiles of geotechnical properties relevant in assessing the seismic amplification. These geotechnical properties are modeled as random variables, in order to include in the model, in a consistent way, the uncertainty associated with the lack of the exact value of these properties in depth. This site effects model can be applied with three main objectives: i) obtaining transfer functions of the response spectrum for risk assessment, ii) generating Shake-Maps for emergency response purposes, and iii) the seismic microzonation of a city and obtaining elastic seismic-resistant design spectra. The methodologies presented here are a first step towards the construction of more detailed models of seismic hazard, which adequately reflect the specific conditions of the region where they are applied. This leads to the definition of more accurate models of seismic risk, to reduce the uncertainties associated with the assessment of the hazard and, therefore, to obtain tighter estimates of losses in order to provide decision makers with reliable information for the proper management of seismic risk.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "La implementación de una metodología de diseño sismo resistente orientada hacia la probabilidad de colapso uniforme requiere una serie de cambios en la metodología de obtención de los parámetros que describen la amenaza frente a la utilizada para el reglamento vigente (NSR-10). En el presente proyecto de grado, se presenta un análisis de sensibilidad de los parámetros asociados a dichos diseños orientados al riesgo de colapso uniforme y el impacto que genera en los parámetros actuales de diseño sismo resistente del contexto colombiano. Para esto, se llevaron a cabo cuatro fases de análisis: (1) la evaluación de la amenaza uniforme en distintas ciudades de Colombia, (2) la sensibilidad de la aceleración máxima basada en riesgo uniforme (SaMCER) debido a variaciones en el parámetro, (3) la sensibilidad del periodo de retorno asociado al SaMCER frente a distintos factores de seguridad y (4) el análisis comparativo de la amenaza uniforme actual frente a posibles valores de amenaza basadas en riesgo. Los análisis comparativos fueron realizados para 6 ciudades del territorio colombiano, ubicadas en zonas de amenaza sísmica baja, intermedia y alta. La evaluación de los espectros se realizó a partir de las aceleraciones espectrales modificadas para periodos de 0.2 seg y 1 seg. En adición, se tuvo en cuenta un periodo de 0.5 seg con el ánimo de comparar el SaMCER obtenido a partir del ajuste del riesgo de colapso uniforme al 1% con el obtenido de las ecuaciones del espectro de diseño de acuerdo con la ASCE 7-16"-- Tomado del Formato de Documento de Grado.

Book Synopsis Small Satellite Missions for Earth Observation by : Rainer Sandau
Download or read book Small Satellite Missions for Earth Observation written by Rainer Sandau and published by Springer Science & Business Media. This book was released on 2010-01-23 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was compiled from contributions given at the 7th IAA Symposium on Small Satellites for Earth Observation, May 4–8, 2009, Berlin (IAA – International Academy of Astronautics). From the 15 sessions for oral presentations and two poster sessions, 52 contributions were selected which are representative for the new developments and trends in the area of small satellites for Earth observation. They re ect the potentials of a diversity of missions and related technologies. This may be based on national projects or international co-operations, single satellites of constellations, pico-, nano-, micro- or mini-satellites, developed by companies, research institutions or agencies. The main focus is on new missions to monitor our Earth’s resources (Part I), and the environment in which our Earth is emb- ded (Part II). Part III deals with distributed space systems, a unique feature of small satellites and in most cases impractical to do with large satellites. Here we concentrate on constellations of satellites with focus on future missions relying on co-operating satellites. For all the new developments and projects we need well e- cated specialists coming from the universities. Many universities included already the development and implementation of small satellites in their curriculum. The u- versity satellites chapter (Part IV) shows the high quality which is already reached by some of the universities worldwide.
