Modelo de evaluación de infraestructura y operación de aeropuertos comerciales regulados por la Administración Federal de Aviación : estudio de caso del Aeropuerto Internacional Luis Muñoz Marín
(2014-07)
A number of methodologies have been developed to assess transportation infrastructure. However, a standard methodology for evaluating airports operational infrastructure does not exist yet. Airports infrastructure factors ...
Estimation of volume delay functions for arterials and freeways in the western region of Puerto Rico
(2011-07)
Volume Delay Functions (VDF) are formulas developed to describe the functional relationship between travel time and traffic flow in a travel demand model considering the available capacity of the facility. VDF’s are the ...
Application of the precursor transformation method to investigate cable tension influence in La Plata Bridge in Puerto Rico
(2015)
Bridge engineers are becoming more interested in structural health monitoring of cable stayed bridges in order to understand and mitigate problems such as from vibrations, fatigue, and corrosion. La Plata Bridge in Naranjito, ...
A methodology to incorporate highway safety into transportation planning using generalized linear mixed models
(2014)
Highway Safety has been identified as a significant problem worldwide. Crashes have been found as the second cause of death in the world according to the World Health Organization (2010). In fact, road crashes cost billions ...
Assessment of potential odor problems on McCook Reservoir, Chicago, IL
(2005-12)
The City of Chicago and neighboring communities are served by combined sewer systems, which carry both stormwater and raw sewage. The combined sewer overflows (CSOs) could exceed the capacity of the wastewater treatment ...
Development of effective width equations of RC slabs and RC box culvert bridges for military load rating
(2015)
This study aims to develop a rapid evaluation method for slab and box culvert bridges subjected to military vehicles; by adopting some of the metrics that already exist in the literature provided by the American Association ...
Enhancement of TCE volatilization and vapor extraction from variably-saturated clay using salt and alcohol solutions
(2015)
One of the most common dense non-aqueous phase liquids (DNAPLs) found in polluted underground systems in the U.S. is trichloroethylene (TCE). Most of the remediation technologies for chlorinated solvents like TCE have been ...
Análisis no lineal tridimensional estático y dinámico de pórticos de hormigón armado con deficiencia en el hormigón de columnas
(2015-07)
This work consisted in developing and programming a three dimensional non-linear analysis model for reinforced concrete structures using the incremental method for the application of loads or displacements and the Newmark ...
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 ...
