Effect of the Periodic Secondary Irregularity on the Dynamic Behaviour of Railway Bridge-Vehicle System
The deformation and vibration of bridge will be developed due to the moving vehicles, especially for railway bridge. The dynamic deflections in the points under each wheel are called secondary...
Dynamic Response of Bridges Under Traffic Loads
Numerous analytical and experimental investigations have been carried out in the past to study the complex dynamic problem of the response of a bridge deck to a moving vehicle. However,...
A Program Architecture for Interactive Nonlinear Dynamic Analysis of Structures
This paper discusses a general object-oriented architecture for use in nonlinear dynamic structural finite element analyses. In light of the special issues surrounding such analyses, the...
Simulation of ATIS Strategies to Mitigate Special Event Congestion
This research extends the performance and application of DYNASMART, a dynamic traffic simulation model which incorporates the three elements necessary for modeling traffic flow under information:...
Computer Methods Used on Seismic Retrofit Projects
Over a relatively short period of about twenty years, personal computers (PC's) have replaced slide rules in most engineering calculations. PC's are now staple equipment in every engineering...
A Spatial Decision Support System for Vehicle Routing
This paper describes the design, development, and implementation of a computer aided system for planning efficient network maintenance routes. The system has been used to design snow and...
Qualitative Formulation of Load Paths Through a Functional Description of Structures
The past few decades have seen major advances in computer tools to analyze complex structures and loadings. For the most part, these programs have focused on two areas - A, programs for...
Stress Analysis in Concrete with Cooling Pipes
A substructure method of finite element analysis is adopted in this paper to simulate heat transfer and thermal stresses in a concrete dam. The massive concrete structure is cooled by...
A Dynamic Mapping Application for an ATIS
A dynamic mapping application for an Advanced Traveler Information System (ATIS) is described. The application requires tracking maintenance vehicles so that paths can be displayed indicating...
PDS: An Expert System for Distress Diagnosis of Flexible Pavements in Taiwan
Pavement distress diagnosis requires a significant amount of engineering judgement which is difficult, if not impossible, to be quantified. This is an excellent domain for the development...
An Application of Neural Networks to Hysteretic Modeling of Steel Structures
This paper describes an application of the neural networks to realistic hysteretic modeling. The neural networks learn from sample data (training cases) and make predictions for new cases....
Non-linear Analysis of a Cable Stayed Bridge
A concrete single-pylon cable-stayed bridge has been analyzed to investigate the ultimate capacity. Two different methods were used to investigate the nonlinear behaviour. First, a simplified...
Computer-Aided Guyed Tower Analysis for the Rehabilitation of TTI Tower, Baltimore
A large guyed television tower owned by Television Tower Inc. of Baltimore is currently being analyzed in order to evaluate the capacity of the tower to support additional broadcasting...
Deriving Alternative Structural Modifications Based on Qualitative Interpretation at the Conceptual Design Stage
Current computer tools provide little support in deriving alternative modifications based on qualitative structural interpretation of a conceptual design. This paper presents a behavior-based...
Reducing Ambiguity in Qualitative Reasoning
Qualitative reasoning derives the behavior of a physical system using a representation of the fundamental principles for the domain. In qualitative reasoning parameters are mapped into...
IVHS and HOV Facilities
This paper examines the application o f intelligent vehicle-highway systems (IVHS) technology to high-occupancy vehicle (HOV) facilities. Current projects are described and potential applications...
A Numerical Procedure to Compute Bearing Capacity of Shallow Foundations
A simple numerical procedure of calculation of bearing capacity of shallow foundation is proposed. This procedure employs the Terzaghi-Prandtl model of general shear failure. In this paper,...
