A finite element-based approach for predictions of rigid pile group stiffness efficiency in clays
(Springer Verlag, 2013-08-17)
This paper presents a finite element parametric study of several variables that affect the stiffness efficiency of rigidly capped pile groups with a view to developing a solution for preliminary design purposes. Previous ...
Biaxial loading of offshore monopiles: numerical modelling
(American Society of Civil Engineers, 2016-05-18)
In this study, finite-element (FE) modeling was used to examine the influence of biaxial lateral loading of a monopile foundation. Two different soil models were adopted to investigate the influence of state-dependent and ...
Development of a global energy management system (GEMS) for the life sciences industry
(NUI Galway, 2015-08)
For multi-national companies, assessment of cost effective energy efficiency projects across a global site base is a complex problem involving multiple variables. This research project proposes a novel methodology for ...
Energy transfer ratio for hydraulic pile driving hammers
(NUI Galway, 2016-08-29)
The ability of hydraulic pile driving hammers to overcome energy losses during freefall enables a greater proportion of the impact energy to be transferred to the pile in comparison to diesel hammers. This percentage, ...
Diagnostics and intervention methods for façade retrofit of post-WWII non-domestic buildings in Europe for energy efficiency
(NUI Galway, 2016-08-29)
The growing demand of deep façade retrofits in refurbishment projects across Europe, is often accompanied by low-energy targets and architectural attributes. Factors like variability in context, material, environment and ...
Shaft resistance of driven cast-in-situ piles in sand
(NRC Research Press, 2015-06-25)
Driven cast-in-situ (DCIS) piles are classified as a large displacement pile, despite sharing certain aspects of their construction with replacement pile types. However, there are relatively few case histories of load tests ...
Pile group settlement estimation: suitability of nonlinear interaction factors
(American Society of Civil Engineers, 2015-06)
In this paper, predictions of pile settlement determined by appropriate superposition of two-pile interaction factors are compared with those computed from continuum analysis. A finite-element package is used in conjunction ...
Numerical modelling of pile foundation angular distortion
(Elsevier, 2015-05-16)
In this paper, the PLAXIS 3-D Foundation finite element (FE) software package, in conjunction with the nonlinear Hardening Soil (HS) constitutive model, is employed in an extensive parametric study of the angular distortion ...
Real-time control of occupants thermal comfort in buildings
(International Building Performance Simulation Association, 2015-12-07)
Providing satisfactory indoor environmental conditions, air quality and thermal comfort through adequate ventilation is crucial in maintaining safe, healthy and comfortable buildings. Since, heating, ventilation and air ...
Pyritiferous mudstone-siltstone: expansion rate measurement and prediction
(Geological Society, 2015)
The expansion rates of a pyritiferous Irish mudstone-siltstone fill material have been measured over a period of 19 months in an apparatus devised to replicate underfloor conditions. The testing, performed in a ...
