Bridge Evaluation Using a Hybrid Information System
The objective of this paper is to discuss the developments and implementation of a hybrid system consisting of a rule-based information system and hypermedia technology for use by inspectors...
Civil Engineering and Civic Monuments: The Commissioning, Design and Public Perception of Urban Infrastructure Projects
This paper analyzes the roles that some infrastructure projects play as civic monuments and public places, and how these functions interact with their technical performance and utility....
A Generalized Approach to the Local Stability of Stiffened Plates: Part I?Mathematical Formulation
The paper describes a generalized approach for the determination of the buckling stress of stiffened plates under combination of uniform biaxial compression, in-plane bending and shear...
A Generalized Approach to the Local Stability of Stiffened Plates: Part II?Approximate Solution
The paper presents an approximate solution for the prediction of the buckling stress of stiffened plates under combined loadings. A closed form expression is presented for the buckling...
Non-Linear Solution Methods for Shell and Spatial Structures
Non-linear solution methods are investigated for the analysis of shell and spatial structures based on limited memory quasi-Newton updates. Under the proposed implementation the preconditioned...
Explorations in Geodesic Forms
Geodesic forms constitute an important family of structural systems. The objective of the paper is to show how the concepts of a mathematical tool called formex algebra and its programming...
Fabric Structures for Public Buildings
The design of the enclosure structure of the new Denver Airport derived from twenty years of experience with the design and engineering of fabric structures for permanent buildings. This...
Direct and Modal Analyses for Shape-Finding of Unstable Structures
Shape-finding analysis of unstable structures has been presented by using generalized inverse (Tanaka and Hangai, 1986). The 'Modal Analysis' using rigid body modes is elegant, but the...
The Structuring of a New Architectural Landscape
Structure plays an increasingly important role in the language of architecture design. Examples from the 2nd half of the 20th century, including transportation systems and buildings, sport...
How to Optimize Light-Gage, Cold-Formed Steel Beams
The Illustrative Examples section of the AISI Cold-Formed Steel Design Manual (AISI 1989) demonstrates how to analyze a number of different cold-formed steel sections. This paper applies...
An Automated Environment for Parallel Computing
Research on a prototype concurrent software development environment for large-scale structural engineering computing is currently underway at Purdue University. This environment is being...
Timing Analysis of a Multiprocessor Architecture for Active Control
This paper describes how real-time multiprocessor systems, such as those required for active structural control, can be developed to satisfy timing requirements on hardware and software....
SQP Methods for Inverse Airfoil Design
We consider inverse design problems of systems governed by suitable discretizations of a boundary value problem (BVP). We present and examine a Sequential Quadratic Programming (SQP) method...
EPA's Environmental Monitoring and Assessment Program: Availability of Broad-Scale Environmental Data and Opportunities for Use in Environmental Modeling Applications
The Environmental Monitoring and Assessment and Program (EMAP) has collected a suite of environmental data over a four year period from estuarine systems in the mid-Atlantic and Gulf of...
NDBC Wave Data?Current and Planned
The National Data Buoy Center (NDBC) of the National Weather Service (NWS), operates a large number of buoy and fixed-platform environmental data reporting stations in geographical areas...
Design and Testing of the NDBC Wave Processing Module
The U.S National Data Buoy Center (NDBC) has developed a new wave data acquisition and processing system, called the Wave Processing Module (WPM), using state-of-the-art technologies and...
ASA.WAVES: An Interactive PC-based Wave Forecasting Tool
An interactive PC-based system for wave refraction-diffraction in coastal regions has been developed, based on a Mild-slope equation finite element wave model. The system includes an embedded...
Airport Terminal Design Challenges
In February 1989, the Metropolitan Washington Airports Authority began the process of designing and constructing a new terminal at Washington National Airport to address the needs of its...
Rail-Air: A Multi-Modal Opportunity in a Changing World
The purpose of this Paper is to examine the applicability of rail links to major airports and the benefits they can bring. It will seek to identify the key success factors and the extent...
BPA Realtime Hydrologic Forecasting System for the Columbia River Basin
Bonneville Power Administration (BPA) markets and distributes the hydroelectric power produced at 30 federal projects in the Columbia River Basin. In order to plan the System's coordinated...
