Finite Element Representation of Approach Slabs
Approaches to bridges are designed to provide a smooth and safe transition from the highway pavement to the bridge deck and back to the highway pavement. Generally this transition area,...

The Automation of Freeway Ramp Junctions Analysis
Congestion on urban freeways has been steadily increasing. In contrast, capacity expansion, by means of constructing new roadways, has not kept pace with the growth in demand. The primary...

Object Based Visualization of Physical Behavior
In engineering science, the physical behavior of solids, fluids, gases and multiphase systems is analyzed with computational models. Numerical methods form the basis of the computational...

An Object Oriented Approach to Computing with Structural Components
The structural analysis process can be modeled in two separate steps: definition of structural systems and analysis of a discrete numerical model; the transmission between these two models...

Using Data Flow Diagrams to Study Communication Process Between Construction Project Participants
The Architecture-Engineering-Construction (AEC) industry is characterized as being highly fragmented. A large number of diverse organizations participate in the planning, design, and construction...

Computer-Aided Decision Model for Selecting a Contractual System
An owner of a construction project often faces the problem of selecting a contractual arrangement. The process of selecting a contractual system depends on the owner's preferred risk sharing...

Linear Scheduling: A Practical Implementation
This paper describes the features and use of a family of planning structures that provides the basis for a superset of the traditional critical path method which includes linear scheduling....

Application of Computer Simulation in the Research of Rail Structure Vibration Reduction
The wheel/rail system is described here as a random vibration system, and the state variables are expressed with quadratic evaluation function. The passive control problem of the random...

The Optimum Parameter Selection for 4-Point Time Domain Integration Schemes
In this paper, a general method of time dimension discretization based on the idea of finite element is presented for dynamic analysis. Two kinds of recurrent formulations are derived...

What is Multimedia Computing?
Computing changed dramatically in the 1980s. The emergence of the personal computer desktop as a standard has spawned the existence of an incredible 60 million personal computers worldwide....

A Structural Engineering Education Image Database
An interactive multimedia environment has been developed to allow students and instructors access to digital images from case studies of structures and structural failures. In this multimedia...

An interactive beam analysis program called GT BEAM, that has been developed at Georgia Tech for use in undergraduate mechanics courses, is presented. The development objectives of the...

Thin-Walled Finite Element for Curved Multicell Box Girders
The generalized Vlasov's thin-walled beam theory was combined with the finite element technique to develop a new curved thin-walled multicell box girder finite element which can model...

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 Finite Difference Approach to the Modelling of Thick Bridge Decks
The finite difference method, although well known as an efficient numerical method, was applied in the past, in the case of slabs, only for the solution of thin slabs. In the present study,...

POE System Development Using Personal Computers
This is a report concerning personal computer utilization such as CAD and spreadsheets which are often used establish the investigation, analysis and evaluation method. These are based...
