Reinforcement details in concrete structures are inherently complex. Therefore, the treatment of reinforcements is one of the most influential factors in the accuracy and efficiency of...

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...

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...

Building Object-Oriented Systems for Diagnostic Problems in Civil Engineering
In recent years, rehabilitation and renovation of existing buildings and roads have grown to occupy a significant share of all civil engineering projects. Proper timing of rehabilitative...

Computer Aided Analysis/Design of Overlays in Cracked Road Pavements
In this contribution CAPA, a user-friendly, PC based, finite element system, capable of analyzing and dimensioning pavement overlays is presented. Because of the generality of the finite...

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...

Application of PC Graphics, CADD, and Solid Modeling Techniques to 3-D Structural Stability of Concrete Monolithic Structures
A computer program for computing 3-D overturning and sliding stability (3DSAD) of concrete monolithic structures has been written and is widely used. This paper describes recent advances...

Simulating Paving Fleets with Non-Stationary Travel
Proper selection of equipment and fleet size can yield substantial savings in both time and cost. A simulation model of asphalt-paving operations is presented and impacts of non-stationary...

Integrated Slab Design Automation System Using Knowledge-based Approach
There has been a strong trend towards the integration of computer aided design and engineering during recent years. But all the systems can not provide the completely integrated functions,...

A Simulation of the Quake-response on the Frame with Large Basement-box under the Earthquake from Deep Soil Layer
This paper treats a study of computing vibratory analysis and its comparison with measurements for the earthquake-responses on an actual 19 storied pure frame-structure with its height...

Modular Software for Editing Paper Drawings
Revising, tracking and storing large format engineering drawings has always been an expensive and complex problem for large industries. The management problem became much more complex...

Linking CAD and Expert Systems for Constructibility Reasoning
This paper describes the prototype expert system COKE (Construction Knowledge Expert) that was recently developed at the Center for Integrated Facility Engineering (CIFE) at Stanford University....

The Use of Numerical Rule Processors in Engineering Calculations
A Numerical Rule Processor uses a declarative approach to the processing of engineering calculations. The rules which link the parameters are set out in a separate rule base and the order...

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...

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...

Sonic NDT for Infrastructure Assessment
Sonic Nondestructive Testing (NDT) techniques are valuable tools for assessing infrastructure. Relatively recent innovations in the field can reveal the internal conditions of concrete...

Promoting Management Systems Within Organizations
