Stability charts for uniform slopes in soils with nonlinear failure envelopes
(
Elsevier B.V.
, 2014 , Article)
Based on the results of an extensive parametric study, charts were developed for assessment of the stability of uniform slopes in soils with nonlinear shear strength failure envelopes. The study was conducted using envelopes ...
Condition prediction models for oil and gas pipelines using regression analysis
(
American Society of Civil Engineers (ASCE)
, 2014 , Article)
Although they are the safest means of transporting oil and gas products, pipelines can sometimes fail with hazardous consequences and large business losses. The decision to replace, repair, or rehabilitate depends mainly ...
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 ...
Flexural and interfacial behavior of externally bonded/ mechanically fastened fiber-reinforced polymer-strengthened reinforced concrete beams
(
American Concrete Institute
, 2014 , Article)
The determination of structural behavior requires advanced numerical methods, of which results are substantiated by credible experimental findings. This research aims to create precise finite element models for fiber-reinforced ...
Characteristics of olive mill solid residue and its application in remediation of Pb2+, Cu2+ and Ni2+ from aqueous solution: Mechanistic study
(
Elsevier
, 2014 , Article)
This study investigated the use of untreated olive mill solid residues (OMSR) as a solid extractant for Pb2+, Cu2+ and Ni2+ ions from aqueous solution. It was shown that the solution initial pH value affected the metal ...
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 ...
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 ...
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 ...
