Accounting for the influence of the free surface on the vibration response of underground railway tunnels: A new iterative method
(
KU Leuven - Departement Werktuigkunde
, 2020 , Conference Paper)
This paper presents a new method for calculating the ground-borne vibration from shallow underground railways. The method is based on an iterative wave-scattering approach, which decouples the problem into two sub-systems: ...
Analysis of the Trajectories of Left-turning Vehicles at Signalized Intersections
(
Elsevier B.V.
, 2020 , Conference Paper)
Internationally, an annual number of more than a million fatalities are caused by road traffic crashes, with particularly signalized intersections being crash prone locations within the highway system. An accumulation of ...
Comparison of site-specific and empirical correlations for drained residual shear strength
(
ICE Publishing
, 2020 , Other)
The discusser has an interest in the topic of the paper (Hayden et al., 2018) on the ability of empirical correlations to predict the residual friction angle of samples from a specific site. In fact, he provided one of the ...
Bond durability of basalt FRP bars to fiber reinforced concrete in a saline environment
(
Elsevier
, 2020 , Article)
This study investigates the influence of basalt fiber reinforced concrete (BFRC) on the bond durability of helically wrapped basalt fiber reinforced polymers (HWBFRP) bars subjected to harsh saline environmental conditions. ...
Undrained interface shear strength of fine-grained soils for near-shore marine pipelines
(
ASTM International
, 2020 , Article)
The peak and residual interface shear strengths for a variety of normally consolidated soils were measured using a torsional ring shear apparatus modified to suit soil and interface testing under the undrained condition, ...
Optimization of Viscoelastic Metamaterials for Vibration Attenuation Properties
(
World Scientific
, 2020 , Article)
Metamaterials (MMs) are composites that are artificially engineered to have unconventional mechanical properties that stem from their microstructural geometry rather than from their chemical composition. Several studies ...
Evaluation of Federal Highway Administration’s Traffic Noise Model for Pavements in Qatar
(
Springer Nature
, 2020 , Book chapter)
Traffic noise is an irritating problem especially for residents near major transportation corridors. It’s in the interest of transportation agencies to check the noise level to develop measures to reduce noise if it exceeds ...
Characteristics, benefits, challenges, and socio-cultural factors of implementing pbl in qatar
(
Aalborg University
, 2020 , Conference Paper)
While project-and/or problem-based learning has been implemented in higher education worldwide for several decades, both modes of PBL remain a new phenomenon in Qatar. Over the past few years, several research projects ...
Short-term flexural performance of seawater-mixed recycled-aggregate GFRP-reinforced concrete beams
(
Elsevier
, 2020 , Article)
Combining seawater, recycled coarse aggregate (RCA), and glass fiber reinforced polymer (GFRP) reinforcement in concrete is potentially advantageous from a sustainability perspective. This paper reports on the results of ...
A novel empirical method for predicting concentration polarization in forward osmosis for single and multicomponent draw solutions
(
Elsevier
, 2020 , Article)
Concentration polarization is one of the inherent problems in forward osmosis membrane process. A quantitative evaluation of concentration polarization is therefore vital to understand its impact on the performance of the ...
