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 ...
Análisis dinámico y evaluación sísmica de la represa de contrafuertes Guayabal
(2008-11)
Esta tesis presenta el análisis dinámico y la evaluación sísmica de la represa de contrafuertes Guayabal ubicada en Juana Díaz, Puerto Rico para establecer conclusiones preliminares en cuanto a su integridad estructural ...
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 ...
Amortiguamiento en estructuras de acero utilizando materiales viscoelásticos
(2007)
En esta tesis se evaluó la efectividad de materiales viscoelásticos para disipar energía en edificios de acero mediante simulaciones numéricas con elementos finitos. El material se aplicó con tratamientos a cortante y ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
