Modeling load effects of water on coastal structures using STAR CCM+ software
(2019-07-11)
Global warming brings as consequence an alteration in precipitation and increase in the sea water level. These consequences generate flood loads in structures near to the coast. The forces generated by these floods are: ...
Performance of landfills with coal combustion byproducts aggregates as an alternative reactive daily cover
(2012-05)
A landfill is an engineered facility for the disposal of wastes. It is designed and operated to minimize public health and environmental impacts. However, land availability is the limiting factor for the operation and ...
Statistical optimization of pervious concrete pavement containing fly ash and engineered iron oxide nanoparticles for runoff quality and quantity controls
(2014)
Portland cement pervious concrete (PCPC) usage has increased due to its potential to reduce storm water runoff and related pollution. Partial Portland cement substitution by fly ash (FA) in concrete production has the ...
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 ...

(2008-11)
Este trabajo presenta un modelo para la selección, diseño, análisis de viabilidad y análisis económico de sistemas de energía renovable para acueductos comunitarios en Puerto Rico utilizando paneles fotovoltáicos y ...
The use of unmanned aerial vehicles as a platform for site inspection, topography and earthwork volume calculations
(2019-12-03)
In recent years, the use of Unmanned Aerial Systems (UAS), or Unmanned Aerial Vehicles (UAV) has become popular in various industries, including construction. Even though the use and capabilities of UAVs is now firmly ...
Strong motion duration influence on nonlinear seismic response.
(2018-12-11)
The preferred representation of seismic hazard in structural design and assessment continues to be based on the elastic response spectrum. Even when dynamic time history analyses are required, the acceleration time histories ...
