Assessment of tire-pavement noise by using on-board sound intensity (Obsi) method in the state of qatar
(
CRC Press/Balkema
, 2017 , Conference Paper)
Tire-pavement noise is the dominant source of traffic noise especially at medium and high speeds. Thus, various transportation agencies and researchers are actively investigating for establishment of accurate test methods ...
Evaluation of Noise Performance of Multi-Lane Highways in the State of Qatar
(
Institute of Physics Publishing
, 2019 , Conference Paper)
In recent years, a growing number of people are complaining to transportation authorities for the traffic noise as a result of increased traffic volume on the highways. Therefore, transportation authorities are actively ...
Characterization and application of FRCM as a strengthening material for shear-critical RC beams
(
EDP Sciences
, 2018 , Conference Paper)
This paper investigates the effectiveness of fabric reinforced cementitious matrix (FRCM) systems in shear-strengthening of reinforced concrete beams. Three types of FRCM systems were considered, namely, polyparaphenylene ...
In-service video-vibration monitoring for identification of walking patterns in an office floor
(
International Institute of Acoustics and Vibration, IIAV
, 2018 , Conference Paper)
Footfall-induced vibrations in office floors can create significant problems for the occupants and facility owners. Such vibrations cannot be modeled by traditional load models since the vibration response of a floor depends ...
A simple method to assess walkability around metro stations
(
Inderscience Enterprises Ltd.
, 2018 , Conference Paper)
The ability to walk or ride a bike safely to and from metro stations is essential to the success of any metro service, especially for car users switching to the service. The main purpose of this study is to develop and ...
Evaluation of traffic noise in the state of qatar
(
CRC Press/Balkema
, 2018 , Conference Paper)
Mitigating traffic noise is a major concern for transportation departments worldwide. A number of noise mitigation procedures are recognized to control noise emitting from traffic stream. However, noise reduction potential ...
Ground-borne vibration investigation by model-ling the tunnel-soil interaction using a finite element package
(
International Institute of Acoustics and Vibration, IIAV
, 2018 , Conference Paper)
In 2013, Qatar Rail announced major rail projects that include an urban rail network for the city of Doha with lines running on the surface and underground which are expected to be in operation by 2020. Railway systems are ...
Defect based risk assessment model for prioritizing inspection of sewer pipelines
(
American Society of Civil Engineers (ASCE)
, 2018 , Conference Paper)
In presence of financial constraints and dire need for inspecting deteriorated sewer pipelines, inspection prioritization tools are required. This paper presents a defect based risk assessment model for prioritizing ...
Investigating the behavior of railroad ballast in a box test under sinusoidal & simulated train loading
(
National Technical University of Athens
, 2019 , Conference Paper)
The use of railway transportation systems has been increased throughout the years. Conventional ballasted tracks have been widely used in many countries around the world. Ballast material is the basic element in ballasted ...
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 ...
