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 ...
Assessment of abnormally low tenders: a multinomial logistic regression approach
(
Taylor and Francis Ltd.
, 2017 , Article)
This study was performed in order to reveal factors affecting abnormally low tenders (ALTs) and to minimize negative effects of them. A thorough literature review was carried out to observe past research about the reasons ...
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 ...
Effect of crushable blockouts on a full-scale guardrail system
(
Taylor and Francis Ltd.
, 2017 , Article)
Since the performance of the guardrail system depends in part on the compatibility of vehicle-to-roadside hardware, it is important to improve the interaction of the vehicle with the guardrail system by adding more compliance ...
Real-time vibration-based structural damage detection using one-dimensional convolutional neural networks
(
Academic Press
, 2017 , Article)
Structural health monitoring (SHM) and vibration-based structural damage detection have been a continuous interest for civil, mechanical and aerospace engineers over the decades. Early and meticulous damage detection has ...
Influence of particle morphology on 3D kinematic behavior and strain localization of sheared sand
(
American Society of Civil Engineers (ASCE)
, 2017 , Article)
The constitutive behavior of sheared sand is highly influenced by particle morphology, gradation, mineralogy, specimen density, loading condition, stress path, and boundary conditions. The current literature lacks a ...
Optimization of linear zigzag insert metastructures for low-frequency vibration attenuation using genetic algorithms
(
Academic Press
, 2017 , Article)
Vibration suppression remains a crucial issue in the design of structures and machines. Recent studies have shown that with the use of metamaterial inspired structures (or metastructures), considerable vibration attenuation ...
Simulation-Based Condition Assessment Model for Sewer Pipelines
(
American Society of Civil Engineers (ASCE)
, 2017 , Article)
Condition assessment models are considered as an evaluation tool that can be used by decision makers to accurately evaluate and assess the condition of pipes. Condition assessment of pipes helps in reaching better decisions ...
The effect of end bearings on the dynamic behaviour of floating-slab tracks with discrete slab units
(
Taylor and Francis Ltd.
, 2017 , Article)
This article builds on previous work in the literature to investigate the dynamic effect of end bearings between consecutive slab units of floating-slab tracks. The work considers a floating-slab track with discrete units ...
Underage driving and seat-belt use of high school teenagers in Qatar
(
Taylor and Francis Inc.
, 2017 , Article)
Many crashes occur every year that involve drivers who are unlicensed and underage. One of the main challenges for traffic safety authorities is the lack of detailed information about this alarming phenomenon. This study ...
