This paper describes the various features of the bridge management system being developed by NET Corporation as part of a project funded by the National Cooperative Highway Research Program...
Bridge Management System Implementation at CALTRANS
Development of a new generation of Bridge Management System (BMS) capabilities has been a high priority for CALTRANS for the past four years. Although the Department has had a bridge inventory...
Intelligent Optimal CAD (IOCAD) for Arch Dams
The artificial intelligence, optimization methods and CAD techniques are mixed to develop an integrated system for design of arch dams. It includes a knowledge base, a data base, a stress...
CAD System for Structural Aesthetics of Bridge Form
An exploratory design process for aesthetic bridge structure is proposed in this paper through developing a prototype of comprehensive CAD system. This process is conceived not only for...
A Study on Aseismic Behaviours of Composite Trussed Arch Bridge
Composite trussed arch bridge is a new type bridge structure developed in China recently, It has the following features: good integrality, reasonable inner force distribution, great spanning...
Implementing Qualitative Reasoning for Structural Design Using Constraint Propagation
All designs begin with qualitative reasoning and therefore, this activity has an important influence upon subsequent quantitative stages. In structural design, qualitative reasoning starts...
Nonlinear Trial Load Method of Arch Dams
The trial load method is still an important method for the stress analysis of arch dams at present. However, the trial load method can be used only for the linear elastic analysis of arch...
Secondary Member Contribution to the Behavior of Damaged Multigirder Highway Bridges
This paper examines the effects of secondary members (cross bracing and diaphragms) on the prediction of the response of damaged simple span steel multigirder bridges. Extensive analytical...
Time-Dependent Analysis of Nonprismatic Curved PC Box Girder Bridges
The purpose of this paper is to present a step-by-step computer method for predicting the deflection and stress distribution duo to creep and shrinkage of concrete in nonprismatic, curved,...
Rive, Rive-Grown and Burst Probability of Rolled Compressive Concrete Arch Dam
The rive, every step of the rive grown and even burst of arch dam are regarded as sequence random events. Making use of the probability theory and the achievement of elastic, elastic-plastic...
The Application of Gauss Numerical Integration Method in Arch Dam Trial-load Method Program
The characteristics of Gauss Numerical Integration Method are the unequal distance between nodes and fairly high accuracy. When the number of nodes is n, the algebraic accuracy can be...
Highway Speed Radar for Pavement and Bridge Deck Evaluation
Radar has been developed as an economical alternative evaluating pavement layer properties and estimating quantities of deterioration in bridge decks. These highway applications are based...
Bridge Monitoring Through Sensor Data Synthesis and Interpretation
The objective of this paper is to outline efforts at the West Virginia University Constructed Facilities Center (CFC) to develop and implement a system for interpretation and synthesis...
Corrosion Model for Concrete Structures
The high basic environment created by concrete pore water protects the reinforcing steel from spontaneously corroding. Chloride ions destroy the passivity of steel in concrete and the...
The State of the Art of Bridge Management Systems
The development of Bridge Management Systems, and Pontis in particular, requires states to change many of their traditional inspection and record-keeping procedures. If these are changed,...
Automated Generation of NBI Reporting Fields from Pontis BMS Database
Methods to generate National Bridge Inventory (NBI) condition ratings for deck (Field 58), superstructure(Field 59), substructure (Field 60) and culvert (Field 62) from the bridge database...
