Improved Image Analysis for Evaluating Concrete Damage
(American Society of Civil Engineers, 2006)The use of images, whether in routine maintenance, or postearthquake reconnaissance, has quickly become the preferred approach to record and archive the exterior damage of existing infrastructure. Postsurvey analysis of ... -
Exploring Concrete Slump Model Using Artificial Neural Networks
(American Society of Civil Engineers, 2006)Fly ash and slag concrete (FSC) is a highly complex material whose behavior is difficult to model. This paper describes a method of modeling slump of FSC using artificial neural networks. The slump is a function of the ... -
General Approach for Training Back-Propagation Neural Networks in Vibration Control of Multidegree-of-Freedom Structures
(American Society of Civil Engineers, 2006)A general approach is proposed for back-propagation training of multilayer feed-forward (MLFF) neural networks for active control of earthquake-induced vibrations in multidegree-of-freedom structures. The training functions ... -
Ontology-Centered Knowledge Management Using Information Retrieval Techniques
(American Society of Civil Engineers, 2006)The paper argues that an effective solution to information and knowledge management (KM) needs of practitioners in the construction industry can be found in the provision of an adapted knowledge environment that makes use ... -
Open Access—Maximizing Research Impact in the Internet Age

Internet-Enabled Remote Observation and Control of a Shake Table Experiment
(American Society of Civil Engineers, 2006)This paper describes a computational framework and the corresponding interfaces required to convert a shake table experiment for remote access including control, observation, and protection from misuse. The laboratory ... -
Bayesian Network for E/M Impedance-Based Damage Identification
(American Society of Civil Engineers, 2006)A Bayesian network is a probabilistic representation of the multiple cause-effect dependency relationships in a domain. It incorporates human reasoning to deal with sparse data availability and to determine the probabilities ... -
Framework to Support the Representations of Semantic Mappings for a Hybrid Integration Strategy
(American Society of Civil Engineers, 2006)To provide an integrated information system for decision support, many previous studies focused on a strategy of sharing a common semantic model among heterogeneous data sources. Such a strategy has many advantages; however, ... -
Performance of Parallel Implementations of an Explicit Finite-Volume Shallow-Water Model
(American Society of Civil Engineers, 2006)Explicit total variation diminishing finite-volume schemes are being adopted on a widespread basis for the solution of depth-averaged hydrodynamic equations. Explicit schemes are constrained by the Courant-Friedrichs-Lewy ... -
Application of Web Services for Structural Engineering Systems
(American Society of Civil Engineers, 2006)The Internet has revolutionized the way computing is done and the way software systems work. Many systems, such as search engines and PC games, have utilized Web-related technologies for Web-based systems. However, the ... -
System Wide Data Quality Control of Inductance Loop Data Using Nonlinear Optimization
(American Society of Civil Engineers, 2006)One of the main criticisms and concerns over the years about inductive loop detector (ILD) data is systematic errors in the data associated with noncatastrophic malfunctioning of the devices. Most of the current approaches ... -
Multi-Agent Framework for General-Purpose Situational Simulations in the Construction Management Domain
(American Society of Civil Engineers, 2006)The need for contextually rich education environments in construction management suggests the development of a general-purpose situational simulation framework that can be used by independent developers to build effective ... -
Human-Assisted Obstacle Avoidance System Using 3D Workspace Modeling for Construction Equipment Operation
(American Society of Civil Engineers, 2006)Equipment operation on construction sites is a major source of construction accidents and injuries related to crushing, electrocution, and falls. Primarily, this is because the operator’s field of view, reaction speed, ... -
Computer Representation to Support Conceptual Structural Design within a Building Architectural Context
(American Society of Civil Engineers, 2006)Computer support for conceptual design of building structures is still ineffective, mainly because existing structural engineering applications fail to recognize that structural design and architectural design are highly ... -
Visualizing Search and Solution Spaces in the Optimum Design of Biaxial Columns
(American Society of Civil Engineers, 2006)Optimum detailing of reinforcement bars for biaxial columns is a nontrivial task and there is no guidance in the codes of practice on this issue. Conventional methods of producing a single design solution and the use of ... -
Automated Estimation of Average Stopped Delay at Signalized Intersections Using Digitized Still-Image Analysis of Actual Traffic Flow
(American Society of Civil Engineers, 2006)Average stopped delay for a given signalized intersection approach is the average time a vehicle waits at a traffic light and constitutes a part of the measure of effectiveness of signalized intersections. The exploratory ... -
Interpretation of Automatically Monitored Lifting Equipment Data for Project Control
(American Society of Civil Engineers, 2006)Interpretation of the data that can be collected by automated monitoring systems on construction sites is the most significant challenge to providing useful management information. Distinct construction operations must be ... -
