Modeling Beam Torsion in Prestressed Concrete Box Beam Bridges
This paper briefly summarizes the development of a specialized finite element model capable of predicting the elastic and inelastic behavior of beam-slab type prestressed concrete spread...

NOISE?A Comprehensive Software Library for Highway Noise Analysis
The Noise Software Library is a collection of highway noise analysis software tools that are arranged together under a powerful file management system which provides a transparent method...

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...

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,...

Grillage Analogy for Multigirder Bridges
Grillage analogy is a method frequently used to simulate the structural response of highway bridges with reinforced concrete deck and steel girders. This approach saves substantial efforts...

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...

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...

A Rezoning Procedure for Finite Element Analysis of Rubber-like Materials
In this paper, we propose a rezoning procedure for finite element analysis of rubber-like materials. Rezoning procedures connect the distorted mesh and the newly created and undistorted...

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...

Computerized Approach for Forecasting the Rate of Cost Escalation
This paper reviews the treatment of escalation in construction costs. The causes of escalation are outlined and the effect of escalation on the contractor and the owner is discussed. Various...

Conceptual Cost Estimating: A Hybrid Neural-Expert System Approach
This paper presents a hybrid neural-expert system approach for developing conceptual cost estimates based on historical data of construction projects. The proposed hybrid neural-expert...

An Integrated Computer-Based Total Design Environment for Civil Engineering Education
The nature of design within the professional practice of civil engineering today, combined with the curricular and content requirements for design of the Accreditation Board for Engineering...

GT BEAM ? An Interactive Graphic Beam Analysis Program for Education
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...

Public Utilities GIS: Promises and Pitfalls
Geographical Information Systems (GIS) and public utilities are natural partners. Municipal public utilities departments and other public works agencies rely on geographical information...

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...
