Dynamic lateral response of single piles considering soil inertia contribution
(2007-05)
The most widely used model to perform the analysis of piles under lateral loads consists in modeling the pile as a series of beam elements and representing the soil as a group of unconnected, concentrated springs perpendicular ...
Evaluación computacional de la efectividad del método lineal equivalente para la estimación de la respuesta inelástica de pórticos de hormigón resistentes a momento
(2018-12-11)
This thesis examined an approximate method to calculate the nonlinear seismic response of structures known as the Equivalent Linear Model (ELM) which seeks to approximate the true nonlinear response through a series of ...
Finite element modelling of multilayer metallic foam cladding systems for retrofitting reinforced concrete walls to mitigate the effects of explosions
(2016)
In the last decade's blast loads caused by intentional explosions had acquired great importance. The analysis of structures subjected to this type of loads and its design to mitigate their effects have been and still is ...
Uso de microtemblores para determinar los periodos fundamentales en Ponce, Puerto Rico: aplicación del método de Nakamura y los Espectros de Potencia de Densidad Espectral
(2013-05)
A significant portion of the damage caused by earthquakes worldwide is associated with the amplification of seismic waves due to local site effects. The evaluation of local site effects is done with site response analyses ...
Recommendations of bridge distribution factors for military vehicles on steel beam bridges
(2007)
Analyses were carried out to develop live load distribution factors for the seven
most common US Army military vehicles on ninety steel multi-beam bridges. The
bridges were analyzed by the finite element method (FEM) to ...
Use of ambient vibration measurements to estimate site fundamental periods at Condado and Isla Verde, PR
(2016-12)
The knowledge of the natural periods of soil deposits in urban areas can be very valuable for the safe design of structures to avoid resonance conditions. This thesis presents a study aimed to estimate site natural periods ...
Evaluation of structural damage identification methods based on dynamic characteristics
(2005)
In this thesis, structural damage identification methods based on changes in the dynamic characteristics of the structure are examined and new methodologies are also developed. These are based on the modal curvature matrix, ...
Influencia del comportamiento inelástico de pórticos especiales de hormigón armado en la respuesta sísmica de componentes no estructurales
(2016)
Se ha demostrado que considerar la respuesta sísmica de los componentes no estructurales de un edificio es de vital importancia, ya que en muchas ocasiones edificios bien diseñados sobreviven el sismo pero su funcionamiento ...
Response of ISO containers to a variety of dynamic loadings at different standoffs: Comparison of field experimentation and finite element modeling
(2021-05-14)
Intermodal cargo containers, such as the International Organization for Standardization (ISO)
containers, are use in a daily basis for transportation of merchandize. The development of the
intermodal cargo containers ...
Determinación de periodos fundamentales del suelo mediante vibraciones ambientales en el Municipio de Humacao, Puerto Rico
(2014-05)
The Nakamura’s technique has been used worldwide to determine site fundamental periods. The technique is to calculate and plot H/V spectral ratios from ambient vibrations recorded over the ground. Ambient vibration ...
