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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
