New design considerations for seismic isolated buildings in Colombia
An important percentage of Colombian population is located in medium-to-high seismicity zones (NSR-10, 2010). Therefore, it is important to protect the buildings, principally the highly crowded ones, and those that are ...
Analysis of seismic pounding of moderate-height RC buildings with aligned slabs
Collision between adjoining buildings is relevant, since the huge impact forces significantly modify the buildings dynamic behaviour. The separation required by the regulations avoids pounding; however, even in recent ...
Análisis estructural sísmico de edificios de acero : un enfoque probabilista
The main objective of this thesis is the probabilistic assessment of the expected seismic damage in steel buildings located in Mexico City. Although a deterministic analysis is performed both, seismic actions and buildings, ...
Evaluación sísmica de edificios de mampostería no reforzada típicos de Barcelona : modelización y revisión de la aplicación del método del espectro de capacidad
Currently, there are very few programs specialized in seismic analysis of unreinforced masonry buildings. Most studies have focused on the seismic behavior of the walls or (in a 3D level) have not integrated the flexibility ...
Advanced computationally efficient modeling of RC structures nonlinear cyclic behavior
Under severe seismic excitation, structural behavior of buildings and other constructions is highly complex. It involves, among other issues, soil-structure interaction, large strains and displacements, damage, plasticity, ...
Vulnerabilidad y daño sísmico de edificios porticados de hormigón armado, irregulares en planta, en Barquisimeto, Venezuela
In this research, the seismic response, the vulnerability and the expected damage in rein-forced concrete residential buildings, with irregular plants, are analyzed. This irregularity is mainly due to inbound and outbound ...
Análisis estructural probabilista orientado a evaluación del daño sísmico con aplicaciones a tipologías constructivas empleadas en Costa Rica
The damage assessment of structures under seismic actions, must seek the implementation of new theories, tools and procedures that reduce the uncertainty associated to the expected structural response of a building. This ...
Design and validation of structural health monitoring system based on bio-inspired algorithms
The need of ensure the proper performance of the structures in service has made of structural health monitoring (SHM) a priority research area. Researchers all around the world have focused efforts on the development of ...
Detección fina de cambios laterales en la geología superficial y en los suelos y caracterización de su influencia en la respuesta sísmica local : aplicación a Barcelona
A complete and reliable Seismic Soil Response prediction requires a thorough knowledge of the Geotechnical and Geological structure, as well as algorithms to find the transfer function. This fact entails a significant ...
Vulnerabilidad sísmica en edificaciones porticadas compuestas de acero y hormigón armado
In this study it was assessed the seismic behavior of framed buildings with composite structure of steel and reinforced concrete (RC) in a specific configuration formed with lower levels with RC (primary structure) and ...
Seismic vulnerability analysis of midheight steel buildings in Bogotá
A number of mid-height steel buildings have been erected recently in Bogotá. Their seismic risk might be high, given the new microzonation of Bogotá and the lack of comprehensive previous studies; noticeably, the response ...
Evaluación holística del riesgo sísmico en zonas urbanas y estrategias para su mitigación : aplicación a la ciudad de Mérida-Venezuela.
The risk coming from natural hazards is usually assessed in physical terms by estimating the losses they may cause. Nevertheless, the risk assessment can involve such aspects as the lack of economic and social development, ...
Robust damage detection in smart structures
This thesis is devoted to present some novel techniques in Structural Health Monitoring (SHM). SHM is a developing field that tries to monitor structures to make sure that they remain in their desired condition to avoid ...
Análisis estructural estático y dinámico probabilista de edificios de hormigón armado. Aspectos metodológicos y aplicaciones a la evaluación del daño.
Esta tesis propone una metodología de evaluación del daño sísmico basada en el método del espectro de capacidad pero con un enfoque probabilista que se apoya en simulaciones Monte Carlo. Así la acción sísmica, la estructura ...
Análisis y gestión del riesgo sísmico de edificios y sistemas esenciales
Los daños por terremotos en edificios y sistemas esenciales han motivado la definición de estándares de comportamiento de estas instalaciones, buscando reducir las pérdidas económicas y la pérdida de funcionalidad. Varias ...
Design and validation of a structural health monitoring system for aeronautical structures.
Structural Health Monitoring (SHM) is an area where the main objective is the verification of the state or the health of the structures in order to ensure proper performance and maintenance cost savings using a sensor ...
Proposal of energy spectra for earthquake resistant design based on turkish registers
This work proposes design energy spectra in terms of an equivalent velocity, intended for regions with design peak acceleration 0.3 g or higher. These spectra have been derived through linear and nonlinear dynamic analyses ...
Un Nuevo enfoque de los precursores sísmicos: monitorización de la interacción frágil-dúctil de la litosfera y su relación con grandes terremotos
The main goal of this thesis is to test the brittle-ductile (BD) interaction hypothesis of the lithosphere. The model uses the correlation of two parameters, the seismicity characterizing the brittle part and the attenuation ...
Modelización numérica del comportamiento estructural de barras de pandeo restringido
The energy dissipators are passive components that are incorporated into buildings and other structures undergoing dynamic excitations, especially earthquakes. Its purpose is to absorb the greatest part of the input energy, ...
