Active vibration control of flexible cantilever plates using piezoelectric materials and artificial neural networks
(
Academic Press
, 2016 , Article)
The study presented in this paper introduces a new intelligent methodology to mitigate the vibration response of flexible cantilever plates. The use of the piezoelectric sensor/actuator pairs for active control of plates ...
Effect of surface roughening on concrete/trm bond
(
ISEC Press
, 2017 , Conference Paper)
Textile reinforced mortar (TRM) is applied on the concrete surface with the aim of strengthening reinforced concrete structures. The performance of the strengthened structural system is directly related to the bond between ...
Stadium vibration assessment for serviceability considering the vibration duration
(
Canadian Society for Civil Engineering
, 2017 , Conference Paper)
Vibration problems in grandstand structures have been getting more attention due to increasing slenderness of architectural components and the complexity of crowd loading for structural designers. The vibration serviceability ...
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 ...
A semi-analytical beam model for the vibration of railway tracks
(
Academic Press
, 2017 , Article)
The high frequency dynamic behaviour of railway tracks, in both vertical and lateral directions, strongly affects the generation of rolling noise as well as other phenomena such as rail corrugation. An improved semi-analytical ...
Nonexplosive Deconstruction of Steel Girder Highway Bridges
(
American Society of Civil Engineers (ASCE)
, 2017 , Article)
While the transportation system of the United States rapidly ages and expands, there is increasing demand for the demolition, replacement, modification, or rehabilitation of existing bridges; all of these actions require ...
Analysis of change orders in Qatari construction projects
(
Taylor and Francis Ltd.
, 2017 , Article)
Change orders affect the performance of construction projects and may induce significant cost overruns. The paper identifies the main causes/factors that lead to change orders in Qatari construction projects. It also ...
Locating leaks in water mains using noise loggers
(
American Society of Civil Engineers (ASCE)
, 2016 , Article)
Because of their potential danger to public health, economic loss, environmental damage, and energy waste, underground water pipelines leaks have received more attention globally. Researchers have proposed active leakage ...
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 ...
Multi-Criteria Decision Making Models for Water Pipelines
(
American Society of Civil Engineers (ASCE)
, 2016 , Article)
The deterioration of water pipelines leads to impaired water quality, increased breakage rate, and reduced hydraulic capacity. The planning of maintenance programs for water pipelines is essential to minimize health and ...
