Durability of calcium-aluminate based binders for rapid repair applications
(2016-05)
Within the last few decades, the amount of vehicle miles traveled within the US has increased approximately 40% with the construction of new roads only increasing 4% during this same time period. This dramatic increase ...
Behavior of the cast-in-place splice regions of spliced I-girder bridges
(2015-08)
Spliced girder technology continues to attract attention due to its versatility over traditional prestressed concrete highway bridge construction. Relatively limited data is available in the literature, however, for ...
Strength, stiffness, and damage of reinforced concrete buildings subjected to seismic motions
(2016-05)
Current analytical tools were calibrated mainly using pseudo-static experimental investigations of individual structural components. Relatively few tests have been performed on reinforced concrete structural systems under ...
Analysis of the shear behavior of prestressed concrete spliced girders
(2016-08)
Implementation of the spliced girder technology in bridges has been growing in recent years. Increased girder lengths can now be realized by splicing shorter precast segments to produce a long span. The research conducted ...
Fatigue behavior of post-installed shear connectors used to strengthen continuous non-composite steel bridge girders
(2016-08)
Many older bridges in Texas are constructed with floor systems consisting of a concrete slab over steel girders. A potentially economical means of strengthening these floor systems is to connect the existing concrete slab ...
Inverse source problems for focusing wave energy to targeted subsurface formations: theory and numerical experiments
(2016-08)
Economically competitive and reliable methods for the removal of oil or contaminant particles from the pores of geological formations play a crucial role in petroleum engineering, hydro-geology, and environmental engineering. ...
Membrane bioreactor treatment of household light greywater : measurement and effects of phosphorus limitation
(2013-05)
As water stresses increase across the U.S., interest in household water reuse is growing. Such reuse typically focuses on light greywater, that is all wastewater generated in the house excluding toilet waste and kitchen ...
Shear behavior of reinforced concrete bridge pile cap girders strengthened with carbon fiber reinforced polymer (CFRP) strips and CFRP anchors
(2016-08)
Externally bonded CFRP strips are ideal for rehabilitating existing members due to their high tensile strength-to-weight ratio, relatively low cost, formability, and expedited installation times. However, without proper ...
Application of diffusive gradient in thin-film passive samplers to assess mercury availability and mobility in a fresh water river system
(2015-12)
The accurate measurement of mercury in sediment porewater is a challenge using conventional sampling techniques which commonly require removal of sediment, transportation, and processing. Passive sampling is an alternative ...
On Bayesian estimation of spatial and dynamic count models using data augmentation techniques : application to road safety management
(2015-08)
Over the past several years, roadway safety management has evolved into data-driven or evidence-based science. The corner stone of a data-driven roadway safety management is the knowledge about useful patterns in the complex ...
