Despite tremendous advances by women in the natural and applied sciences, where in selective fields women have surpassed men in the earning of doctoral degrees for more nearly 20 years, female enrollment levels in engineering ...
Bridge Weigh-In-Motion systems measure bridge strain caused by the passing of a truck
to estimate static axle weights. For this calculation, they commonly use a static
algorithm that takes the bridge influence line as ...
Geotechnical characteristics of Dublin Boulder Clay (DBC) based on detailed site
investigation and site experience from some recent large projects in Dublin are presented.
This paper attempts to synthesise available ...
Creation of an environment in which shallow geothermal energy can thrive
will require a coherent approach and a high level of collaboration with professionals from
countries that have developed technical expertise in the ...
Detailed analysis of potential water chemistry and settlement issues associated with the installation of open-loop geothermal
systems is infrequently carried out. This has led to the failure of several previously installed ...
Rehabilitation of building structures is a critical need facing numerous older urban areas. Many of these structures are supported on pile groups, which do not have adequate load capacity to support the demands expected ...
The experimental procedures and results are presented for a one-tenth scale laboratory investigation of changes in achievable grouted zones through alterations in helical pier parameters. The parameters investigated were ...
Site-specific assessment of the loading to which existing bridges are subject has considerable potential for saving on rehabilitation and replacement costs of the bridge stock. Monte Carlo simulations, with traffic ...
A new development on treatment wetland technology for the purpose of achieving high rate nitrogen removal from high strength wastewater has been made in this study. The laboratory scale alum sludge-based intermittent ...
The Water Framework Directive has been the catalyst for a considerable amount of data collection, analysis and research covering a wide range of physical and biological characteristics and involving a wide range of scientific, ...
A periodic monitoring of the pavement condition facilitates a cost-effective distribution of the
resources available for maintenance of the road infrastructure network. The task can be
accurately carried out using ...
Phosphorus (P) in agricultural runoff is a major pollutant in many of Ireland's surface waters. Identification of areas that are at a high risk for P loss to surface waters is a critical component of river basin management. ...
There are numerous studies on the dynamic amplification factors caused by traffic
flow on a bridge. For short- and medium-span bridges, the road profile appears as a
dominant parameter on the bridge dynamic response. In ...
Upland headwater streams are dynamic systems, responding rapidly to changes in climatic conditions. This study examined the effects of a catastrophic rainfall event, that occured on 24 October 2011 on the east coast of ...
Jet grouting is a ground improvement technique that has become widely adopted over the past three decades, yet relatively little data has been published about performance characteristics of mixes under adverse conditions, ...
To predict characteristic extreme traffic load effects, simulations are sometimes performed of bridge loading events. To generalize the truck weight data, statistical distributions are fitted to histograms of weight ...
In line with the increasing studies on the beneficial reuse of alum sludge from a “waste” into useful raw material, this paper reports an in-depth investigation of the effects of ageing time on the structure and the phosphate ...
Accurate traffic loading models based on measured data are essential for the accurate assessment
of existing bridges. There are well-established methods for the Monte Carlo simulation of single lanes
of traffic, and this ...
Critical static bridge loading scenarios are often expressed in terms of the number of vehicles that are present on the bridge at the time of occurrence of maximum lifetime load effect. For example, 1-truck, 2-truck, 3-truck ...
