Computational buckling analysis of cylindrical thin-walled above-ground tanks
(2005-06)
This thesis evaluates the stability of cylindrical above-ground steel tanks under imposed support settlements and wind pressures. The tanks considered are representative of tanks constructed in Puerto Rico and in the ...
Curvas de fragilidad para estructuras de pórticos de hormigón armado en Puerto Rico involucrando el efecto de las paredes de mampostería no estructurales
(2008)
Las estructuras de pórticos de hormigón armado con paneles de mampostería como relleno representan una porción significativa de las estructuras construidas en Puerto Rico y en muchas partes del mundo. Muchos de los ingenieros ...
Industrial ecology approach to management of fly ash from fluidized bed combustion: production of slow-release fertilizer and soil conditioner
(2006)
Coal has been a major energy source since the Industrial Revolution. Despite its environmental problems, coal consumption is still growing because of the lack of alternatives such as natural gas and petroleum resources. ...

Multi-objective optimization approach for land use allocation based on water quality criteria
(2009)
Surface water contamination by point and nonpoint sources of pollution is a major concern for public and government agencies around the world due to the excessive contamination of water bodies. Water is an important resource ...
Probabilistic-based design factor for the elastic modulus of a pultruded composite material reinforced with a 3D braided preform
(2005-05)
This work describes research aimed to probabilistically assess the mechanical properties of a pultruded fiber-reinforced polymer (FRP) reinforced with a 3D braid and roving. In addition, reliability-based reduction factors ...
Retrofitting of R/C structures on gravity columns using inverted-Y steel bracings
(2007)
It is common practice in Puerto Rico to build elevated reinforced concrete frame and shear wall structures in hillsides and hilly terrains by supporting them on gravity columns. Recent studies have indicated the vulnerability ...
On time-frequency analysis for structural damage detection
(2008)
An integrated study that explores the capability of Time-Frequency Analysis combined with another technique of signal analysis and system identification for damage detection purposes using only output signals is presented ...
Analysis of open canopy structures with parapets under wind
(2009)
A literature review shows that there is a lack of information on the wind load pressures acting on canopy structures with a parapet on the roof perimeter. On the other hand, a large number of those structures suffered ...
