Effects of Random Errors on Space Station Truss
Results of Monte Carlo simulations of structural responses of a finite element model of a space station truss to random member length imperfections are reported The results reveal that...
Elasto-Plastic Analysis of Frames with Bending Moments and Axial Force Interaction
A menu driven computer program has been developed for Nonlinear analysis of plane framed structures. This program utilizes the stiffness method. Only material nonlinearity has been considered....
Dynamic Behavior of a Non-Linear Cable Truss
The equations of motion of a geometrically non-linear cable truss are presented. The behavior of the truss subject to harmonic excitation is studied....
Time-Delayed Control of Nondispersive Continuous Systems
This paper deals with the noncollocated, time-delayed active point control of continuous systems. It considers systems of finite spatial extent which can be modelled by the undamped wave...
Oceanographic Earth Observations by Space Shuttle Astronauts
Thirty years of manned space flights have produced over 100,000 photographs of the Earth. Many of these photographs describe various coastal processes and oceanographic phenomena at a...
Multiple Use Ocean Management in the U.S.: Toward a New Conceptual Framework
Problems with the sectorally based, largely single-purpose approach to the management of ocean resources and ocean space in the United States have been amply documented in recent years....
CADD for Export
By using sophisticated structural design software and high-speed PCs, engineers in Pittsburgh overcame myriad problems when designing a highrise industrial tower in India. First, they...
Fluidization Pipe Hole Spacing
Two-dimensional fluidization experiments are performed on fine (d50 = 0.15 mm) and medium coarse (d50 = 0.45...
Temporary Lateral Support System for Historic Building Facades in Boston
This paper describes a system of vertically cantilevered structural steel trusses, designed by the author, that provided temporary lateral support for a group of five and six story, 120...
Design and Planning of Structural Steel Roll-In
Innovative construction methods were required to erect structural steel inside a 170 foot long box truss over a railroad. The contractor engineered and executed a unique system to roll...
Animation of Automated Space Construction
This paper presents a discussion of Three-Dimensional Computer Animation as applied to the evaluation of Lunar/Mars construction. A number of applications for this type of tool are introduced....
Ultimate Air Rights
The new 1 million sq ft office tower at 450 Lexington Ave. rises from available space between commuter railroad tracks, through the center of a renovated four-story post office and up...
Floating Fabric Over Georgia Dome
The 400,000 sq ft free-span roof cover the new $210 million Georgia Dome may look as festive as a circus tent. But next fall, when the 70,500-seat arena becomes the home of the Atlanta...
Joint Spacing for Airfield Pavement
This paper looks at various factors affecting portland cement concrete(PCC) pavement cracking, with special emphasis on the effect of joint spacing on crack development. A rational approach...
Examples of System Optimization and Reliability in Bridge Design
The objective of this paper is to present examples of system optimization and reliability in bridge inelastic design. The optimum solution is defined as the bridge of least weight, subject...
A Structural System Reliability Analysis of Jacket Using an Improved Truss Model
An improved truss model for structural system reliability analysis of jacket structures is presented. The efficiency of the model makes it possible to carry out a large amount of ultimate...
Development of a Nonlinear Stochastic FEM and its Application
A basic formulation is developed for the nonlinear stochastic finite element method. It is based on the perturbation method and retains its advantage, namely that a nonlinear finite element...
Stochastic Finite Element Analysis of Metal Plate Connected Wood Trusses
A stochastic finite element approach is developed for use in ananlyzing metal plate connected wood trusses. The procedure uses linear beam-column elements to model the wood members. The...
Dynamic Stability of Cable Domes
The cable domes designed by David Geiger for the gymnastics and fencing arenas for the Olympics at Seoul, Korea, and for the stadium at St. Petersburg, Florida, are geometrically non-linear...
Probability Based Bridge Safety Analysis
Traditional methods of quantifying safety of highway bridges have been associated with deterministic analysis. However, ascertaining the true measure of safety, or reliability, should...
