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...

A CAD-Based Construction Simulation Tool Kit for Construction Planning
Current planning and scheduling techniques place considerable reliance on the planners judgement, imagination and intuition. The result of such techniques is typically lengthy text reports...

CAD Applications for Material Handling in the Construction Environment
Research at Va. Tech in the area of dynamic behavior modeling and crane damping have been undertaken. The dynamic behavior modeling capability has been designed to us 3-D CAD models and...

Comprehensive Site Monitoring Through Model Based Reasoning
The authors of this paper have developed a computer object oriented intelligent construction site modeler which is dynamically linked to a 3D CAD system. Model Based Reasoning is used...

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...

A Work Packaging Process Model for Petrochemical Plant Piping Construction
This paper presents a model for the current work packaging process for petrochemical plant piping construction. The basic foundation of the model is formed by identifying major decision...

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....

ICPS: Integrated Construction Planning System by Object-Oriented Planning Models
Knowledge processing for integrated building system planning and construction system planning poses challenging problems to integrate design and construction process efficiently. While...

Floodplain Delineation Using TINS
Triangulated Irregular Networks (TINs) are becoming an increasingly common tool for modeling terrain surfaces on the computer. They are formed by the triangulation of scattered xyz data...

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....

Interdisciplinary Communication of Design Critique in the Conceptual Design Stage
Computer tools provide little support for the communication of design concepts and problems across disciplines. Our objective is to help bridge the communication gap between architects...

Agent-Based Technology for Facility Design Software Integration
The application of a novel technology called Agent-Based Software Engineering to facility design software integration is presented. The technology is founded on the notion of design agents...
