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 ...
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 ...
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 ...
Seismic response of inelastic concrete structures using the equivalent linear method
(2016)
The equivalent linear method is widely used in Geotechnical Earthquake Engineering to calculate the accelerations at the surface of soil deposits subject to earthquakes of moderate intensity. The method approximately takes ...
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, ...
Ground response spectra at surface for Mayagüez considering in-situ soil dynamic properties
(2005)
One dimensional ground response analyses was performed at fifteen sites in Mayagüez
Puerto Rico to study their seismic response for the development of response spectra at the surface. Field experiments using the Spectral ...
Impulse load response of lattice steel columns
(2012)
Many bridges that represent an important part of our nation’s infrastructure system are constructed from steel components including steel plates, beams, columns, and cables of different configurations. Because of their ...
Proyecto piloto para microzonificación sísmica en Puerto Rico: el caso de Mayagüez
(2015)
In this study a seismic microzonation of the city of Mayaguez, Puerto Rico was developed, starting from the design spectrum of the IBC-09 code for rock B. A conventional microzonation project requires substantial funds to ...
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 ...
Seismic analysis of horizontal axis wind turbines
(2010)
The wind energy industry has seen a substantial growth in several industrialized countries in recent years. Traditionally, territories in northern Europe, with a low level of seismicity, have been the leaders in the use ...
