New Observations on the Application of LS-SVM in Slope System Reliability Analysis
(American Society of Civil Engineers, 2017)The stability evaluation of earth slopes is a common practice in geotechnical designs. To account for uncertain characteristics of soil properties, probabilistic evaluation that requires repeated calculations of factor of ... -
Automated Detection of Multiple Pavement Defects
(American Society of Civil Engineers, 2017)Knowing the pavement condition is essential for efficiently deciding on maintenance programs. Current practice is predominantly manual with only 0.4% of inspections happening automatically. All methods in the literature ... -
Modal Identification Using Mobile Sensors under Ambient Excitation
(American Society of Civil Engineers, 2017)The state-of-the-art modal identification for civil structures is limited to the estimation mode shapes with a low spatial resolution. Modal coordinates are identified only at the location of sensors, which are fixed at ... -
Community Sensor Network for Monitoring Road Roughness Using Smartphones
(American Society of Civil Engineers, 2017)Maintenance of ever-expanding road networks all over the world is a critical task and regular monitoring of the road surface is imperative for successful maintenance. Existing monitoring techniques use dedicated vehicles ... -
Evaluation of Vision-Based Measurements for Shake-Table Testing of Nonstructural Components
(American Society of Civil Engineers, 2017)During an earthquake, freestanding equipment and contents in a building may experience large complex 3D motion. Depending on the geometry, mass distribution, and support mechanism (e.g., wheels, casters, legs) of the object, ... -
League Championship Algorithms for Optimum Design of Pin-Jointed Structures
(American Society of Civil Engineers, 2017)In this paper, a new optimum truss design approach based on the league championship algorithm (LCA) is introduced. The LCA is a novel metaheuristic algorithm inspired by sporting competitions in sports leagues. Assuming ... -
Framework of Data Acquisition and Integration for the Detection of Pavement Distress via Multiple Vehicles
(American Society of Civil Engineers, 2017)Street defects, such as potholes and sunken manholes, in general develop quickly compared to other pavement distresses, such as cracking and rutting. Those street defects can result in vehicle damage. This paper proposes ... -
Cloudy with a Chance of Fuzzy: Building a Multicriteria Uncertainty Model for Construction Project Delivery Selection
(American Society of Civil Engineers, 2017)The process of choosing a project delivery method is infused with cognitive uncertainties associated with the decision maker. Fuzzy uncertainties arise because of imprecise understanding and subsequent representation of ... -
High-Resolution DEM Generation of Railway Tunnel Surface Using Terrestrial Laser Scanning Data for Clearance Inspection
(American Society of Civil Engineers, 2017)The current clearance inspection of a railway tunnel is mostly limited to extracting and analyzing 2D cross sections. A novel clearance inspection technique has been introduced to generate the high-resolution digital ... -
Optimum Assembly Planning for Modular Construction Components
(American Society of Civil Engineers, 2017)Geometric variability often creates challenges for component aggregation in the assembly of interchangeable components in modular construction. Despite complete interchangeability-based design, geometric variability resulting ... -
Integration of Data Envelopment Analysis-Based Preference Aggregation Method and α Particle Swarm Optimization Technique into Group Decision Model
(American Society of Civil Engineers, 2017)The design of sustainable infrastructure is a complex process because it involves various fields of expertise such as engineering, economy, environment, social, etc. To make sure experts from various fields are part of ... -
Developing a Virtual Campus Model in an Interactive Game-Engine Environment for Building Energy Benchmarking
(American Society of Civil Engineers, 2016)Energy benchmarking is a critical step of building-retrofit projects because it provides baseline energy information that could help building stakeholders understand energy performance and prioritize potential retrofit ... -
Vision-Based Excavator Detection and Tracking Using Hybrid Kinematic Shapes and Key Nodes
(American Society of Civil Engineers, 2017)Enhancing workplace safety continues to be a major task in the construction industry. Approximately 75% of struck-by fatalities are caused by inappropriate spatial-temporal relationships between construction workers and ... -
Hybrid Procedure for Automated Detection of Cracking with 3D Pavement Data
(American Society of Civil Engineers, 2016)Pavement cracks are considered a major indicator of pavement performance. Because traditional manual crack surveys are dangerous, time consuming, and expensive, technologies have been developed to collect high-speed pavement ... -
Interpreted Information Exchange: Systematic Approach for BIM to Engineering Analysis Information Transformations
(American Society of Civil Engineers, 2016)Transforming a building information model to an engineering analytical model is tedious and time consuming. With the current state of interoperability, after importing the building information model, the designer makes ... -
Two 4D Models Effective in Reducing False Alarms for Struck-by-Equipment Hazard Prevention
(American Society of Civil Engineers, 2016)Over the past decade, several smart and automated systems have been developed to address the issue of struck-by hazards in construction—that is, workers on foot struck by equipment or equipment struck by equipment. False ... -
Roundness and Sphericity of Soil Particles in Assemblies by Computational Geometry
(American Society of Civil Engineers, 2016)The use of computational geometry methods for determining soil roundness (R) and sphericity (S) were evaluated and extended to particles segmented from images of three-dimensional particle assemblies. Two Adobe Photoshop ... -
