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...

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,...

Development of an Integrated System for Structural Design of Buildings Using OODP Method
This study serves as a starting point for the development of an integrated system in the structural design domain. In this paper we describe the issues that arise in the integration throughout...

A Program Architecture for Interactive Nonlinear Dynamic Analysis of Structures
This paper discusses a general object-oriented architecture for use in nonlinear dynamic structural finite element analyses. In light of the special issues surrounding such analyses, the...

Object-Oriented Finite Element Modeling
The present paper studies the suitability of object-oriented modeling strategies for problems of structural mechanics. After a general discussion of the topic, special emphasis is put...

Dynamic Analysis of Beams on a Pasternak Foundation
Since many years pavement engineers apply very simple statical models to analyze their specific problems. The development of numerical tools and easily available computer power make much...

A Generalized Three Invariants Cap Model and its Numerical Implementation to Study Soil-Foundation Interaction
This paper presents a modified cap model that is capable of characterizing cyclic stress-strain behavior of soils and describing variation of shear strength along various stress paths...

Properties in Sensitivity Coefficients of Framed Structures
This paper presents a special relationship among sensitivity coefficients of static response, natural frequency and mode. The relationship is that the sum of sensitivity coefficients in...

Research of the Limit Function About Imperfection and the Approximately Calculating Method of the Internal Forces of Hyperbolic Cooling Tower
The authors use the finite elemental program, which made by themselves and makes use of finite element method with rotational shell, to calculate the deformation in hyperbolic cooling...

Computer Methods Used on Seismic Retrofit Projects
Over a relatively short period of about twenty years, personal computers (PC's) have replaced slide rules in most engineering calculations. PC's are now staple equipment in every engineering...

Modeling and Analysis of Shafts and Tunnels for the SSC
A brief overview of the Superconducting Super Collider Project (SSC) is presented followed by a discussion of the 3D modeling and finite element analysis of tunnels and shafts. The sequential...

Using Finite Element Analysis to Derive the Coefficient of Subgrade Reaction
The coefficient subgrade reaction is a concept used to generate spring constants which are commonly used to model the foundation subgrade in the analysis of mat foundations. This paper...

Developing an Integrated Database Structure for the Lifecycle of Precast Concrete Projects
This paper presents an integrated database structure for the storage and retrieval of information during the planning, design, manufacturing and construction of a structural precast concrete...

An Entity Relationship Model of Construction Project Data
The purpose of this paper is to demonstrate the results of applying techniques of information systems development to an application area that is diverse and complex but which is exploring...

Qualitative Formulation of Load Paths Through a Functional Description of Structures
The past few decades have seen major advances in computer tools to analyze complex structures and loadings. For the most part, these programs have focused on two areas - A, programs for...

A Constraint-Based Composites Design Advisor
Most engineering problems, because they involve mathematical relations (constraints) on real valued quantities (objects), can be reduced to constraint networks. The authors speculate that...

A Knowledge-Based System for the Damage Assessment of Timber Trusses
A knowledge-based system for the maintenance of over two hundred timber Warren truss buildings is being developed at the Royal Military College of Canada by the Knowledge-Based Expert...
