Geotechnical considerations on the design of piled rafts on rock
( Research Publishing Services , 2011 , Conference Paper)This research shows the effect of misestimating the pile spring constant (Kpl) and the modulus of subgrade reaction (Ksg) on design of piled rafts on rock. The high mass stiffness of rock contacting the base of such rafts ... -
Virtual environments for improving construction site safety
( Taylor & Francis , 2011 , Article)This paper aims to present a visual simulation technique for improving construction site safety based on virtual construction environments (VCE). Additionally, the paper presents a framework to conduct true ‘what-if’ ... -
Settlement of axially loaded piles entirely embedded in rock - analytical and experimental study
( Taylor and Francis , 2012 , Article)Finite element analysis was performed to study the settlement behaviour of axially loaded piles entirely embedded in nonhomogenous rock. The elastic modulus of the rock mass was taken to increase linearly along the pile ... -
Review of existing transportation sustainability initiatives and their applicability to Qatar
( American Society of Civil Engineers (ASCE) , 2012 , Conference Paper)Sustainable development is Qatar's main national goal. The fact that Qatar has secured the World Cup bid for 2022 will make it the first Arab country to host the world cup. This honor and Qatar's plan to advance its ... -
Developing a framework for pre-design process simulation for green buildings
( American Society of Civil Engineers (ASCE) , 2012 , Conference Paper)There is an increasing awareness towards the construction of sustainable green buildings. Green rating systems worldwide, such as LEED, are providing standards to aid in the construction of green building. During the ... -
A framework for construction workspace management: A serious game engine approach
( 2012 ASCE International Conference on Computing in Civil Engineering , 2012 , Conference Paper)Construction workspace is regarded as one of the main constraints on construction sites. Construction workspaces are generally difficult to proactively plan and manage due to the dynamic nature of a site where workspace ... -
Disruption factor of asphalt mixtures
( Taylor & Francis , 2012 , Article)Typically, aggregate gradation is selected to meet Superpave mix design specification; however, many Superpave mixtures have exhibited deficient field performance. The porosity of the dominant aggregate size range (DASR), ... -
Developing a framework for calculating LCA normalization factors for the State of Qatar
( Canadian Society for Civil Engineering , 2013 , Conference Paper)Life Cycle Analysis (LCA) has recently emerged as a powerful tool for assessing the environmental impact of materials, systems and processes used in building construction. With its ability to clarify the ambiguities of the ... -
Practical teaching and its importance in teaching civil engineering
( Hamad bin Khalifa University Press (HBKU Press) , 2013 , Conference Paper)Students pursuing their civil engineering degree usually learn the theory part in class but may struggle to relate theory to practice if the instructor has no industry experience. Engineering graduates can benefit more ... -
Bearing Capacity and Settlement of Skirted Shallow Foundations on Sand
( American Society of Civil Engineers (ASCE) , 2013 , Article)The behavior of axially loaded skirted shallow foundations resting on sand was studied using an extensive numerical analysis. Surface, pier, and skirted square foundations resting on sand with different shear strength ... -
Measuring construction materials price fluctuation risk
( Canadian Society for Civil Engineering , 2013 , Conference Paper)Construction projects costs are believed to be highly susceptible to a combination of internal and external factors. One of these factors is the prices of construction materials and the risk of their fluctuation. This paper ... -
The significance of industry experience in civil engineering education
( Hamad bin Khalifa University Press (HBKU Press) , 2013 , Conference Paper)Students pursuing their civil engineering degree usually learn the theory part in class but may struggle relating theory to practice if the instructor have no industry experience. Engineering graduates can benefit more ... -
Finite element modelling of shear strengthened reinforced concrete beams
( International Institute for FRP in Construction (IIFC) , 2013 , Conference Paper)This research aims at creating precise finite element models for FRP shear strengthened concrete beams. It is inspired by the fact that the determination of the structural behaviour of the shear strengthened beams requires ... -
A solid-phase extractant based on microemulsion modified date pits for toxic pollutants
( Elsevier , 2013 , Article)Application of microemulsion modified raw date pits as an inexpensive solid extractant for removing methylene blue (MB), copper ion (Cu2+) and cadmium ion (Cd2+) has been presented. The results summarised herein are also ... -
Status quo and critical review of PPV safe limits for subsurface construction blasting close to low-rise buildings
( Taylor and Francis - Balkema , 2013 , Conference Paper)Subsurface construction blasting may result sever man-made ground vibrations.Waves generated due to detonating a charge in a solid medium like rock generate particle movement and travel at different wave velocities. As ... -
Scales of flows: Qatar and the urban legacies of mega events
( Emerald , 2013 , Article)In 2022, Qatar will become the first Middle Eastern and Arab country to host such an important Mega-Event as the FIFA World Cup. Global cultural and sporting Mega Events have driven the urban transformation of cities such ... -
Simplified vibration response prediction for slender monumental stairs
( American Society of Civil Engineers (ASCE) , 2014 , Conference Paper)Slender monumental stairs are major architectural features in hotels, condominiums, hospitals, and other high-end building structures. Architectural requirements for these are usually very aggressive, with long spans and ... -
Evaluation of Combined Excavation Waste and Reclaimed Asphalt Pavement Aggregates for Use in Road Bases and Sub-bases
