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 ...
A variable damping semiactive device for control of the seismic response of buildings
(2005)
This dissertation proposes a new semiactive device, composed of two fixedorifice viscous fluid dampers installed in the form of V whose top ends are attached to the upper floor and their lower ends to a point that can move ...
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 ...
Bending and shear load rating of an arch ring bridge
(2011)
This MS thesis entails an analytical study of the structural behavior of a concrete arch beam from the Lahontan Dam Spillway Bridge located in the city on Fallon, NV. This comes as a necessity from the U.S. Army Corps of ...
Assessment of directional combination rules for the seismic analysis of nuclear power plant structures
(2020-07-22)
To assure the safety of Nuclear Power Plant structures, it is crucial to design them in a way that guarantees the continuous function of systems, structures, and components (SSC) after the seismic event has passed. Seismic ...
Ambient vibration measurements to estimate site fundamental periods in Aguadilla and Aguada, PR
(2019-05-14)
Considering the high risk of seismic activity of the island of Puerto Rico, this research is aimed at determining the fundamental natural periods of the soil deposits in two areas, downtown Aguadilla and the Espinal ...
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 ...
Experimental study of the use of crumb rubber as a structural component in slender steel elements
(2018-12-12)
Facing a serious waste management problem, the accumulation of scrap tires
represents a huge environmental and health problem not only to Puerto Rico, but also to
many nations. It is necessary to consider alternatives ...
Periodos fundamentales de sitio utilizando microtemblores: comparación con otros métodos y aplicación a Mayagüez, Puerto Rico
(2009-11)
Most of the earthquake damage is caused by the amplification due to local geological conditions of the seismic waves propagating from the bedrock. A simple and efficient way to characterize the geological conditions is the ...
Dynamic properties and seismic response of the cable structures and towers of the Arecibo Observatory
(2006-05)
This investigation was requested by the staff of the Arecibo Observatory to determine whether the towers and cables that support the suspended platform are capable of resisting a maximum-credible earthquake in the elastic ...
