Computer Analysis of Cable-Stayed & Suspension Bridges
The finite element structural analysis of long span bridges is an area of research that has been studied within the past thirty years since the development and emergence of the digital...

The Application of AI in Highway CAD System
In a conventional CAD System, the process for solving a certain particular engineering problem is fixed stationary in the program. As a result, the program is often modified to fit different...

Object Oriented Modeling of Structural Systems
Computational engineering in structural design is no longer restricted to numerical approaches. Increasingly, also non-numerical, in particular, cognitive problems can be implemented into...

Object-Oriented Modelling for Concrete Structures
The use of computers for the design process has reached wide acceptance. The use is developed in several fields such as CAD, CAM or programs for design of structural elements. Recent work...

Object-Oriented Data Exchange for the Integration of Design Processes in Structural Engineering
The computer integration of tasks, activities, tools, user and data exchange interfaces, management of knowledge etc. requires a new approach by object-oriented modeling in civil engineering....

A Model to Quantify Work Space Availability for Space?Contrained Scheduling Within a CAD Environment
In any given process work area, a task or activity requires a specific amount of space for its execution. This required space must be accommodate by the physical space of the work area...

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,...

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...

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
