Reducing railway-induced ground-borne vibration by using open trenches and soft-filled barriers
(
Elsevier Ltd
, 2016 , Article)
A trench can act as a barrier to ground vibration and is a potential mitigation measure for low frequency vibration induced by surface railways. However, to be effective at very low frequencies the depth required becomes ...
Assessment of the taxi service in Doha
(
Elsevier Ltd
, 2016 , Article)
This research focuses on passengers' satisfaction of the taxi service in Doha, Qatar. Qatar is a rich developing country where taxis are widely considered as a public transportation service due to the limited use of the ...
Diaphragm shear strength and stiffness of aluminum roof panel assemblies
(
Elsevier Ltd
, 2016 , Article)
A diaphragm is an assembly of planar structural elements interconnected to each other to provide in-plane bracing system and transmit in-plane forces. The diaphragm geometry, supporting frame, type of the panel profiles, ...
Investigation of Weather Impacts on Pedestrian Volumes
(
Elsevier B.V.
, 2016 , Conference Paper)
This study investigates the impacts of temporal and weather characteristics on pedestrian volumes in a hot climate condition. A major neighborhood located in an urban area in Doha, Qatar was chosen as a case study site. ...
Mitigation of railway-induced vibration by using subgrade stiffening
(
Elsevier Ltd
, 2015 , Article)
Railway-induced ground vibration is often associated with sites with soft ground. Stiffening of the subgrade beneath the railway track is one particular measure that has potential to reduce the vibration level at such ...
Textile-Reinforced Mortar (TRM) System as a Strengthening Technique on Reinforced Concrete Beams
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
There is considerable investment in construction industry in Qatar for civil infrastructures and taking into account the severe environmental conditions, they would entail for proper maintenance, repair and strengthening ...
A comparative study of the treatment of ethylene plant spent caustic by neutralization and classical and advanced oxidation
(
Academic Press
, 2015 , Article)
The treatment of spent caustic produced from an ethylene plant was investigated. In the case of neutralization alone it was found that the maximum removal of sulfide was at pH values below 5.5. The higher percentage removal ...
Inexpensive strengthening technique for partially loaded reinforced concrete beams: Experimental study
(
American Society of Civil Engineers (ASCE)
, 2015 , Article)
This paper constitutes a special importance for developing countries where an affordable trowel-based strengthening system is needed. This paper also provides an affordable strengthening solution when it is not possible ...
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 ...
Experimental determination of carbamate formation and amine protonation constants in 3-amino-1-propanol-CO2-H2O system and their temperature dependency
(
Elsevier
, 2015 , Article)
The equilibrium constant for the formation of carbamate in 3-amino-1-propanol-CO2-H2O system was evaluated at different CO2 loadings, different temperature values, and different amine protonation constant. The studied ...
