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....

Computing with Objects: What Does Industry Hope to Gain from it
Although the need for an integration of engineering tasks has been stressed for a long time, the success that we see in this regard is very limited. We believe that there is justified...

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...

Knowledge and Information Processing with Drawing Objects in Construction Phase
Knowledge processing by CAD systems poses challenging problems for the efficient integration of design and construction processes. While CAD systems have been applied to various phases...

Computer Application in Analyzing Change Order Work
In heavy construction, particularly on large tunnel projects, numerous tasks are often performed and inspected simultaneously. The project specifications and contract documents require...

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...

Advanced Construction Technology System
The Advanced Construction Technology System (ACTS) is a computer database for the classification, documentation, storage and retrieval of information about emerging construction technologies....

Finite Element Analysis and Design of Bridges with Applicatrons of ICAD
This paper describes applications of client-server models, interprocess communications (IPC), and concepts of intelligent CAD (ICAD) to the interactive design and analysis of highway bridge...

Safety of Passengers on Railway Platforms?Using Various Computers
Recently, it has become very important to take measures to improve platform safety in Japan. Many passengers use railway platforms all day long (from the first train to the last train)....

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...

Managing AutoCAD and Intergraph MicroStation Systems
The reality today is that Computer Aided Design information is being transferred from one CAD system to another. More often, sharing CAD information among the design team requires multiple...

Recommendations for the Design of CAD User Interfaces
The user interface of a CAD system appears to the users to be the system itself. Thus its design is very important. For this reason the committee 4.2.1 'Computer Aided Design' of the Gesellschaft...

3D Template of Human Figure for CG Animation in Design
It has become commonplace to use computer graphics (CG) animation in architectural and landscape design. Historically, CG animation has been employed primarily as one of many presentation...

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...
