Numerical modeling of shear strengthened reinforced concrete beams using different systems
(
American Society of Civil Engineers
, 2014 , Article)
This research aims at creating finite-element models for fiber-reinforced polymer (FRP) shear strengthened concrete beams. It is inspired by the fact that the determination of the structural behavior of shear strengthened ...
Uptake of Reactive Black 5 by pumice and walnut activated carbon: Chemistry and adsorption mechanisms
(
Korean Society of Industrial Engineering Chemistry
, 2014 , Article)
The potential of using pumice and walnut wood activated carbon as low-cost adsorbents for the removal of the diazo dye Reactive Black 5 (RB5) from aqueous solutions was investigated. The Langmuir isotherm fit to the data ...
Evidential Reasoning–Based Condition Assessment Model for Offshore Gas Pipelines
(
American Society of Civil Engineers (ASCE)
, 2016 , Article)
Condition assessment of oil and gas pipelines is a significant component in pipeline operations and maintenance. Such assessments are used to ensure better decisions for repair and/or replacement to reduce pipelines’ failure ...
Estimating the elastic settlement of vertically loaded single piles in rock
(
Trans Tech Publications
, 2014 , Article)
An extensive finite element analysis was performed to study the settlement behavior of vertically loaded piles entirely embedded in non-homogeneous rock. To avoid utilizing interrelated parameters, pile-rock relative ...
Evaluation of Combined Excavation Waste and Reclaimed Asphalt Pavement Aggregates for Use in Road Bases and Sub-bases
(
OMICS International
, 2014 , Article)
More than 15 million tons of aggregates are imported each year to Qatar from neighbouring countries. Large quantities of waste materials (around 20 million tons/year) from excavation waste, demolition rubble and reclaimed ...
A chronological exploration of the evolution of housing typologies in Gulf cities
(
Springer
, 2016 , Article)
This paper traces the evolution of housing typologies in four major cities in the Gulf region, namely Doha, Dubai, Abu Dhabi and Manama. The study reviews the formation and historical events in the region, which had a ...
Integrated performance assessment model for water distribution networks
(
Taylor and Francis Ltd.
, 2016 , Article)
The American infrastructure report card in 2013 rated the US water system infrastructure with grade of ‘D’. The Canadian infrastructure report card in 2012 stated that around 15.4% of Canada’s water infrastructure has a ...
Use of local discarded materials in concrete
(
Elsevier
, 2014 , Article)
Steel slag, a by-product of steel manufacturing, is generated in large quantities in Qatar. In fact, it is estimated that more than 400,000tons of steel slag are generated annually in the country. Gravel, resulting from ...
A model for predicting failure of oil pipelines
(
Taylor & Francis
, 2014 , Article)
Oil and gas pipelines transport millions of dollars of goods everyday worldwide. Even though they are the safest way to transport petroleum products, pipelines do still fail generating hazardous consequences and irreparable ...
Combined influence of temperature and flow rate of feeds on the performance of forward osmosis
(
Elsevier
, 2016 , Article)
The effect of the membrane orientation, feeds flow rate, feeds temperature, and combining effect of both temperature and flow rate on the membrane flux was investigated in order to enhance the performance of forward osmosis ...
