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...

Design and Analysis of the 712 Fifth Avenue Structure
New York City's 712 Fifth Avenue is an extremely-slender concrete tube tower. This text addresses the structure's lateral structural system, wind analysis, computer model, thermal analysis...

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...

Blast Demolition of Reinforced Concrete Industrial Chimneys
On some of recently demolished chimneys, transient measurements were taken, in the vicinity of the tilting hinge, during the process of falling down. Thus, corresponding dynamic computational...

Analysis and Design of a Double Layer Barrel Vault with a Large Span
The roof of coal storage in JiaXin Power Station is a double-layer barrel vault. This roof covers span of 103.5 M and a longitudinal span of 88.0 M. The height of this space truss is 3.5...

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...

This paper will provide a case study of the construction of the Hypar-Tensegrity Cable Roof for the Georgia Dome. The paper will emphasize innovative computer analysis of the construction...

Effects of Spatial Triangulation on the Behavior of Tensegrity Domes
A number of long span 'tensegrity' dome type structures have recently been realized pursuant to the inventions of R. Buckminster Fuller and David H. Geiger. These structures have demonstrated...

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...

Multimedia Implications to Structural Engineering
The usage of computer technologies have revolutionized the practice of structural engineering during the past thirty years. The advent of multimedia technologies within computer hardware...

General Structure Representation for Neural Networks
Current applications of neural networks for structural analysis are limited to specific structures. In order to expand the use of neural networks to general structural types, the input...

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...

Large-Scale Computations in Analysis of Structures
Computer hardware and numerical analysis algorithms have progressed to a point where many engineering organizations and universities can perform nonlinear analyses on a routine basis....

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....

Computer-Aided Structural Engineering Software: The Status of Concurrent Engineering
Concurrent engineering encompasses computer-aided engineering (CAE), multidisciplinary CAE (MCAE), computer-aided design and drafting (CADD), computer-aided manufacturing (CAM), computer...

Application of Computer-Aided Structural Engineering
From as early as 1988, the Civil/Structural Group of Bechtel Corp.'s Houston Regional Office has viewed its automated production tools as components of a production system. Intergraph's...

Checking of CAD Drawings for Fabrication Issues
